Chevy / GMC Truck: Crank No Start No Communication With FPCM
HTML-код
- Опубликовано: 2 окт 2024
- Come along with Eric O. at the SMA shop as he has a look at this 2009 Chevrolet 1500 5.3 that was towed in as a crank no start. It has a code stored in it U0109 for "loss of communication with fuel pump control module." You can follow along with Eric O. as he brings you along and diagnosis the FPCM. We also get to use our J2534 Interface device and do some programming.

I have to say that if I lived in New York state, and I needed a good mechanic you would be the first person I'd come to. That's how much you impressed me with your videos.
You are a perfect combination between Eric The Car Guy and Scanner Danner. Very informative and fun to watch! Thank you for your excellent videos, they are very informative!
You gotta have rainman ray in there too, these guys are all solid technicians
I love it. Scanner Danner is the bomb and Eric the car guy also
He's the best..He worked on race cars, for 18 years!
7:06 That’s the perfect location for any electrical module. Salt, moisture..
my mechanic days are over and am so glad i can't even make a smart house switch work to turn on a light but glad some people have patience for this
Wow I just had the same prob in my 2014 Silverado. Found the green crusty at the connector. Truck still started and drove but limited me to 10 mph. The cleaned the connection and put die electric grease and worked fine since.
A thanks for the live diagnosis ,recently dealing with No Comm on few items with my Duramax and have probably read all 7 manuals ,watching you helps confirm The Hands on items as well as GM's format ,it's slowly getting smaller and feeling more confident with putting methods of diagnosing into practice vs looking for the quick and easy spotting a open wire LOL.
The comm lines were a handful ,yet benefits are meant to streamline, ..... I think
Thanks Again
Roman
Eric, you're a virtual mechanic-ing Dynamo! Thanks for all the videos, really enjoy them.
engineers should be a mechanic for a minimum of two years before designing vehicles !!!!
Yes
I agree 100%
ABSOLUTELY!!!! I’ve always said that too!!
@Robert Slackware Ha you're damn right Datsun/Nissan are engineering quality control i had three prior cars in my family from Nissan 1982 Datsun Sentra/1992 Nissan Sentra/2002 Infiniti I35 all with at least 250,000 to 500,000 Miles on the odometers' and now respectively 2016 Nissan Rogue and 2016 Nissan Murano the level of engineering and design their products is bar none. As a independent mechanic they are sometimes a pain in but to work on. It's rare that something major to go wrong (Knock on wood) well at least to me. He'll I'm trying to get a hold of a 1970-73 Zed as a project for. my self.
that will cost gm alot of money.
Good video, your community is lucky to have you to do this kind of work.
Great video.
I am not defending the poor construction (poor seal) or unprotected location of the FPCM but I do believe that the FPCM must be located very close (ie short wire lengths) to the FP and FPS to accurately monitor/meter FP supply voltage. That is why it is not mounted in the cab/cabin or part of the PCM.
I think this is one of those jobs that 'he can do but we cant' - unless you have a $2K programming tool.
Paul
I was absolutely glued to your video. You'd make a great Sherlock Holmes. Well done and thank you.
Just a note to thank you for taking the time to share your knowledge. I have found your videos extremely helpful.
Thanks for this Mr. O, every video you put up of burned up modules and electronicals makes me want to forget buying anything newer than 25 years old. Control modules, reprogramming, how about relays and fuse boxes? Sounds like just more reasons for the manufacturer to make more money with proprietary stuff by locking us into dealership repairs.
With great technology comes great responsibility
Amen on those circuit breakers! I have an f150 kept blowing brake light fuses instantly, plugged in that exact same tool and it worked all the sudden. As you stated I followed the scent which ended up being a melted wire above the headliner for the third brake light. In hindsight I would've used a lower circuit breaker, but I found the short real quick!
Why doesn't GM just mount the module in a bucket of salt water?
more $ from the vehicles up keep
Lol or at least in place of the rear mud flap?
Time for a fresh JEEP hat yet?
Fords does the same thing, right on the frame behind rear left wheel well, nice place for modules. However, does make it easier to change. Would rather change these then dropping the tank and replacing the fuel pump, cheaper too.
There should be a service where all this asshatery gets reengineered or removed, right after you buy a vehicle. Like this moving a computer "indoors", seems like common sense. Just drive straight from the dealer to shop. Call it de-obsolate or unplanned failhood service.
U moved up to my top videos to watch. Your diag skills are beyond anything i ever learned at lincoln tech or in the field.
No disrespect to Eric the car guy, but I enjoy your stuff way more. I'm a new subscriber I haven't watch a lot of your videos but I really like the way you pay close attention to detail. Wrench on buddy👍up.
ETCG seems to have gotten away from the day to day grind of being a mechanic. No disrespect, but payola product review, product placement and Fairmont build vids aren't all that interesting anymore to me.
Ima fan I concur and I've pointed this out before ETCG is way to commercialized now it's all about that Fairmont and the sponsors
toddster772008 I wish Eric made more " fixing it forward" vids
I personally don't think ETCG is half the mechanic Dr. O is. He's trying to make a living off of youtube and all the power to him for that. Eric spins wrenches for his money and we are all lucky that he has decided to take us along for the ride. Thanks Dr.O.
ETCG is a mechanic, but Dr. O is a tech.
I love work, I can sit and watch people work all day long. Great info videos.
lol
the fuse is "still" blown.......I hate it when they don't unblow
I've got a good used GM FPCM that I use for quick easy testing. It's very common here in northern MI for the fuel pump driver to fail.
When your wife said she had it good cause she married you, you should have said I have it better cause I married you. It was your time to shine on camera and you blew it. lol.
Where were ya when I needed ya Jim!?
I guess you missed the video where he told her ..
I made many mistakes in life,but the one mistake I didn't make was marrying you....No words in her part,just blushhhhh....
This one here was her comeback.lol
OMG I feel like i'm watching a soap opera sticking up for Eric here..Hahahaha
Hey Eric it's never to late to say you love her!!!
I was a auto elect. For 17 years. I used a auto reset breaker. Then a current meter induction to find a short. Works well.
D
Let's all pitch in together and get south main auto a 4K camera and their own internet fiber connection.
Not just for weekly videos...
But also as a live streaming shop-cam
Hi Eric I love the way you eliminate fuel pump as potential problem by measuring current on fuel pump circuit. Good work. Cheers.
Love how sealed the module was conseidering its location ... glad they dont make aircrafts
👍
Man when it comes to electrical and finess mechanics your are a beast... You are a real mechanic... Some of the people out here are hammer and chisel mechanics and not very good at their job
"I do have it good, 'cos I married you". Now that's nice!
Greg Monaghan She just said that cause she was on camera😂😂
Smart too. 😉
She's a keeper, aint she?
Nice use of the process of elimination method, you have a nice rapport in communication easement & profiguration routing technique in covering details.
Hey Eric you got it going on dude!! If my wife ever looked at me and said "I do have it good, cuz I married you" - - my mind would explode!! 😂 You got it good Mr. O!
Throwing a CAN Bus and a controller on the fuel pump is over-engineering at its finest. Very thorough troubleshooting!
Wow, watching you diagnose things is just awesome. It's not just the diagnosis, but the fact that you do it quickly, and confirm it 100%. Amazing. Thanks for educating and informing us. Most of all though, thanks for sharing this!
If I ran a shop, the "waiting room" would have a television streaming South Main Auto nonstop; first off, it'd help give the customer some impartial insight regarding the extent of a given repair. That, and when I was under the car watching the same video, they'd be less likely to notice🤫
you probably dont give a damn but does someone know a trick to get back into an instagram account..?
I was stupid lost the account password. I appreciate any help you can give me!
@Mauricio Alfonso Instablaster :)
@Chris Bronson thanks for your reply. I found the site through google and im waiting for the hacking stuff atm.
Takes a while so I will reply here later when my account password hopefully is recovered.
@Chris Bronson it did the trick and I now got access to my account again. Im so happy:D
Thank you so much you saved my account !
For PWM control of a high current load like the fuel pump, you want to minimize the high current wire loop area, meaning you would like the power switching electronics as close as possible to the motor or you will not pass vehicle EMC. For a return-less fuel system you must vary the current through the pump motor to regulate rail pressure. A relay will not regulate current.
The thing I like best about these videos is the comment made by Mrs O. at 39:50 "I do have it good, 'cos I married you". Those of us in happy marriages, really enjoy seeing other couples who also love each other. I notice the negative comments from those who have never experienced a marriage like this one. People actually do feel this way about each other.
I know this is from 5 years ago and you may never see it. but an old guy once taught me you can stick an extension and a swivel thru the holes in the spare and drop the bolt for the entire spare holder and the whole thing will drop on the ground. just watch your head🤣
through the lug holes. and your gonna have to figure out what size i forget but got money on a 15
Another informative video. As the owner of an 05 Silverado, I appreciate this one personally. Thanks for all the detail in troubleshooting that you provide for us all, as well as the needed reprogramming of the new control module.
You just learned something. Your new check on this item should be to use a vacuum hose (small hose) for a "Smell test".
I don’t know if you are still following these comments or whether this was already explained somewhere in the 564 comments, but circuit breakers are not ideal substitutes for fuses, as you discovered, because thermal circuit breakers typically take much longer to trip than a fuse, especially in more marginal overloads (for example, drawing 30-50A on a 20A circuit) - even longer still in dead shorts if they do not also include a magnetic trip element. It takes time to heat the bimetallic spring in a thermal circuit breaker, much longer than it takes to melt the thin wire or metal strip in a sacrificial fuse. This extra time to clear the circuit means that wiring and circuit board traces, etc., can get very hot before the breaker trips even though their operating load ratings are identical...and sometimes they will wind up failing before the breaker can finally do its job. That is part of the reason, costs aside, why fuses are used extensively in vehicles since the wiring harnesses are usually of rather light gauge and not really suited to handling extended overloads without overheating. Ideally, instead of using resettable thermal circuit breakers your kit manufacturer ought to redesign to use resettable *electronic* circuit breakers that better mimic the time versus load characteristics of the fuse you are substituting it for as it would then afford the same degree of protection.
Thank you for the video, this helped me to diagnose and repair a 2011 sierra that had no communication from the fscm
When I retired I has 2 ASE Master certificates and every certifications Ford offered, and more and I'm saying this man is GOOD, or as a friend says "good at it!" Anybody in his area needs to take their problems to him. As to prices, people need to understand that it takes a lot to operate a business like his. The money for tools alone is high and a good scanner alone can cost 10k, or more plus there' are more and more tools needed including special tools that may be needed to work on a certain brand of vehicle. On top of that the overhead in NY is astronomical. A good tech like this man is worth top dollar.
You better believe he is good. Even car companies send their non-functs to him. He is so good I wish he lived near me. Why? Because he is honest. I am sure he has failures but not sure I have seen that come up. His car probably runs like crap that is the way it works
The shop rental alone will keep you up at night not to mention heat electricity etc.
Especially knowing he is honest and up front about it. It’s sad to say that that is getting more rare.
Knewa dude that has 6 of those same "doublecerts"! Tip of the cap sir.
My suggestion would've been to measure resistance of the fuel pump from the circuits in the FPCM connector rather than checking amp draw, we know there's excessive amps, but unless the pump showed no resistance, it's not shorted and the module is to blame. Just my 2 cents
Wonder how many GM truck owners will try to get their spare tire down this weekend?
Haha good luck :)
Thomas Niner I have been soaking my spare tire safety latch with Fluid Film. Maybe it will operate when I need it, maybe not.
It is a 2008
Me... Mine really is just a decoration. Doesn't even have air in it haha.
Mine is a 2002 and it actually comes down i don't think it has the safety latch or it is broken.
Awesome video - love the detailed troubleshooting. Totally Solid. Just had a buddy drop a 2009 Tahoe in my yard that won't start. Battery is low, but hooked up a scanner while charging the battery and got this code - wouldn't go away. I suspect I'll find something similar to what you found when I crack into it in the morning. Thanks man - you just gained a subscriber.
I think it is obvious the vehicle industry is dead set on eliminating the independent shops and the DIYer. But thank God for unselfish people like you and the many others that dedicate their time to teach people like me. They are over complicating everything according to their agenda, it is a plan. GREED. Thanks a million for your time and effort.
There's your problem lady water got Into the fuel pump Control Module and It got the toasted good video Eric O @39:04 @SouthMainAutoRepairLLC
Great diagnostic --- lousy GM design
If you see smoke coming from a load circuit, it doesn’t necessarily mean it is pulling enough current to blow the fuse/circuit breaker.
Hey Eric! Dont mean to armchair quarterback on you bro but this is from an electronic tech to auto mechanic. Just trying to help save you some time. In this case I would have ohmed out the terminals of the FPCM at the module to ground terminal at FCPM (Not on the wiring harness) then ohmed out at the wiring harness (disconnected from FPCM) ground pin to feed to fuel pump. One of them would have been very near zero ohms and the one that did would be the offending part.
The resistance on the fuel pump motor wires can be very near 0 ohms and still be good- any where from 0.2-5 ohms measured depending on the design of and how big the motor is in the fuel pump. Resting resistance and running resistance are going to be totally different.
This /\ /\ /\ . Found out trying this on my Grand Am. Thank god there was no "controller module" for the stupid thing, just a motor and integrated float.
Hey Mrs O like watching you doing your projects ,good job
Astonishing that they put that module where they did considering people use these trucks to tow and launch boats in salt water!
The same thing came to my mind boat ramps.
Seeing you work on a lot of General products, you have the Bosch interface, aka Gm mdi. With the software, you could be running the Gm scan tool via your laptop.
The MDI works best with Global A vehicles. With the trucks, that did not happen until 2014. He could use TECH2 WIN with the MDI, which sucked. When I worked at GM TAC, we found many glitches with the TECH2 WIN. His best bet is to use the TECH2 with a CANdi module.
Proof that conformal coating a circuit board does not make it impervious to failure.
Conformal coating causes more failures than protection, the module and its components expand and shrink with changes in temperature of the board and its components, while the coating resistance to this heat and cooling causes the components soldered leads to break loose from the board. Fuel pumps failures are usually caused by gasoline with alcohol, which attacks the conformal coating on the module and the varnish/coating on the motor windings and armature.
Hello EricO..this is Bob from East Auroa,NY...and just stumbled onto your videos about a week and half ago. So instead of watching the news or stuff like that when I get home from work I been watching SMA because I find it so educational and hilarious. I too remember Grover ...NEAR!!......FAR!!! So I was wondering if you could do a video of Chevy Cruze 2011 PO171 fuel system too lean bank 1 and PO2270 B1S2 lean/rich switch signal malfunction ..both codes (system 00) ...thank you for time for making theses videos.
wow, talking about same thing, Ivan did the same thing. he put silicone on the back of the module to seal it from moisture and road film etc. he applied sealant on the connections to further seal the connections to the module.
@ Eric O. and Josh Benny Hello, Im needing to do something like this for the blind zone alert modules on vehicle. How did this work out? Did he put silicone directly on the board? I've seen some apply nail polish to seal would this maybe work sir this type of application? What kind of sealant would be used on the connections to seal? Just a novice trying to keep vehicle on the road. I appreciate any and all help...Thank you.
I had an awwwww moment eric.when Mrs O said she had it good cuz she married you.keep up the good work with the informative videos with much needed humor cuz some of those jobs are frustrating but you stay calm and cool or is that just good editing lol.
Very good video Eric, Thank You. I would give you 12 thumbs up, to make up for the haters if i could!
Omg! I can’t believe you just said “wet in the box” to your wife on video!😳
The look on her face, she definitely got the joke!!!
I’m still laughing my ass off!!!
youre not lying about that spare not coming out. i needed mine and it would not drop, i even hung on the damn thing and jerked around. after all that it just fell out..
Great video Eric.I learned a lot.One thing I would of done different .not necessarly better would be to power the gray wire with my power probe to see and hear the pump turn on.could also use my low amp clamp 0n the probe tip to check draw.looking forward to more of your videos.question I tried to find your video on ford f150 vacuum hubs to rewatch but i cant find it.?
Also changed mine an didnt have to reprogram it. Plugged it back in an cleared the check engine light an hit the key an it fired right up an ran like champ
Gotta love saltwater + electronics + metal. Nothing like upstate NY. Good job on GM for putting over-complicated electronics in a heavy abuse location on a vehicle meant for abuse situations. There's gotta be one GM engineer who's somewhere in the corporate world going, "I told you fools that location was a terrible idea! Remember that meeting we had in conference room 302 back in 2008?? I told you fools. I told you."
Our world needs more people to take a step back and think simply and logically occasionally.
...and after listening to that engineer bitch and moan, he walked to the accounting office and said..."man we're selling fuel pump modules like hot Cakes! I told you! dumbass engineers..."
You might be misunderstanding the situation though. It's the newer better GM retirement benefits package. Instead of boos, that guy has been promoted and they'll be putting all the brains in as many boxes as they can dream up and all of them will be just an inch or two short on enough sealant to actually work. The plan is clearly working well.
You know just thinking what about on the boat ramp wow that would kill it fast.
Greg Paine the TCM in a pt cruiser is put in the wheel well behind the front bumper. It may be silicone potted. But that didn't stop it from rotting out.
GM is a parts company at this point lol
Thats electronics gone mad! I remember the days the fuel pump ran off a straight 12v. If it didn't work, hit it or change the fuse and that was it!!
Typical shoddy GM engineering. All of these modules should be on the interior of the car or in a sealed box if outside. But, then GM and the aftermarket wouldn't be able to sell as many replacements if they engineered it correctly. JUNK!!
over engineered . just use a relay style
Pessimistic Pizza Volvo's the same . ScannerDanner has a video about Volvo's screw the people and the aftermarket Tech's
Not just GM they all do it.
Where is it looked all over Paul site cant find it?
Its probably only on his premium channel.
I'm working on a 2011 silverado with a 4.8 vortec eng- it came to me with a loud tapping/ knocking noise heard these engines had problems with the VVT units on the front of the cam I cked it & was making a little noise, so the owner opted to go with a VVT delegate kit due to it being a lot cheaper& don't have to work about it going bad again, the kit included a new timing cover & CMP sensor, it didn't fix the problem,icam to the conclusion that that one of the roller lifters had gone bad, so pulled the head on the driver's side & sure enough a lifters had come apart, the owner (a freind) didn't have much money so he wanted to just replace the one bad lifter, the remaining lifters & camshaft looked fine. So, I replaced the bad lifter & flushed the engine clean as best as I could & put it all back together ( oh & I also put a new oil pump on too.) So I primed the oil pump before I started it. The engine fired up instantly & ran beautifully I let it run for about a half hour making sure everything was good, oil pres, water temp etc.. the owner said it sounded better then when he first got it, So went on a test drive & she ran fantastic for about 3 miles & then it died & won't start now. I checked & it's getting spark, I sprayed starter fluid in the throttle body & nothing, it's set a couple codes: P0010, P0340 & P0445. I know it's going to set a code because after the VVT delete kit I need to take it & get the PCM flashed so it won't trigger a the MIL I don't know what code should or shouldn't be set, & was running great, I'm thinking maybe the new CMP sensor might have failed. I could use your help with any sugestions or input you might have.-
P.S. I only have a not too expensive scan tool that can pull some live data, but not everything.
Thanks Robert
Great job. I like your diagnosis procedures.
As another auto professional, I would be interested in the time you charged for the entire job.
U may not be an engineer but you are becoming a certified SPARKY!!
Watching a video from your channel whilst you are watching a video from your channel. WOAH!! *Insert Bill and Ted Gif*
Besides you and I do people know who Bill and Ted are??
Excellent!!!
EXCELLENT !
If you really know who Bill and Ted are, what number am I thinking of? :)
jix177 69 dude!!!!
Ivan just did the exact same module. he sealed the edges of his new one with silicone.. :-)
Manufactured to fail. The funny thing is that the small IC that blew probably costs like .20 cents on fleabay. Take it home tonight and solder another IC on it for the next time you need a FPCM..LOL
Yes but aren't they failing because the seal fails? I mean, if you're going to mount electronics under a care in a plastic box, it had better be hermetically sealed for life. Then again, imagine the heat under there on a hot summer day after a nice long drive, then parked on super heated blacktop.
Chances are it popped due to salt water contamination. Even if you repaired it how long would it go before other gremlins appeared? I tried it with a Rover 200 ECU a few months ago. I fixed 2 bad solder joints and a popped capacitor but there was already green crustys in it and it failed again a few weeks later.
Well it isn't a perfect solution. The best one would be to get that thing inside away from the salt gremlins.
The Plow Guys yes, because gm knows how to think. don't make me laugh, they were almost bankrupt once or twice.
zoidberg444 exactly, the module needs to be fixed then sold back to fleBay ASAP, only problem being not having a vehicle around to verify its operation.
Yadda,yadda,yadda.have learned a lot watching your videos....and sainfeld.
great! Now I'm going to go out and try to crank down the spare on my Xterra. I don't think it's been cranked down the 12 years I've owned it
I know it's late to say anything, but I'd have powered up the pump from the constant power feed and checked if it ran without popping.the breaker . You could've eliminated it very simply upfront. THEN if you suspected any of the other lines, test them.
One of the best shows on RUclips
Wroom Wroom HANDS DOWN!!!
I Find myself wanting to move back to wisconsin more as I get older. Then I watch your videos and i'm all, nah i'm good. I hate rust.
So sweet of your wife to tell that she has a good life with you Eric O. It warmed my heart :-)
She is very good to you and I am sure when you are off camera you are a teddy bear.
I can say that it's a smell you'll never forget. I have gotten quite a few electronic items, that "Quit working" once I take a whiff of it, and smell that.. the diagnosis is pretty easy.
YO ERIC O!!! if you found corrosion in the fuse block... you should of addressed that as well... cuz all the time and effort you put into the FPCM if the fuse block shorts it can cause multiple drive ability // no start / no crank etc concerns....
i get it you wanted it running back on the road ... but chances are you are gonna have it come back with similar issue ( or so the customer will think its the same issue ) and then the fuse block is shorted ...
just a thought from a drive ability tech for GMC down here in texas
and dear god if i had to deal with all that rust and corrosion for everything i did i would hate life lol
The first 21 mins of this U0109 crank no start diagnostics is on point, After that Eric overworked himself. I believe the easier way to check if the fuel pump is the issue would have been to jump the pins for the fuel pump to power and ground on the same harness, Without plugging the harness back into the FPCM. If the fuse pops the problem is either the fuel pump or a short in the wires going to the pump, If the fuse does not pop then the problem is a internal short in the FPCM.
Great job with the videos keep them coming.
Watching now love your videos Mr.O
Too bad GM doesn't encase those electronics in resin. I guess the extra $1.50 would break them.
BMW does it and then when they fail they burn to the ground with all the potted resin as a petroleum fire. The answer is that people don't get what they pay for with domestics because if big three legacy costs and investor demands. They all dissect the reliable makers and then see how cheaply they can copy the newest tech or features everyone now wants. Ask any GM engineer how many Lexus parts he has examined before sitting down to design for the company.
Funny I was just thinking same think. Encase in something to prevent from happening again.
Overheating can become an issue when you encapsulate a circuit board in coatings. Whether or not this board would have that problem, I don’t know. If the engineers were worth a damn, they would do something different though. Finding someone to repair a bad module in a timely manner is next to impossible these days, so the module housing should have just been completely sealed and deemed non-serviceable. Ultrasonically weld the case halves together, bed the connector pins in epoxy, and never worry about it again until the capacitors go bad. Of course, mounting the module in a location that isn’t absolutely asinine, would help too...
gm filed for bankruptcy when the financial colasped hit. gm took bail out money
Resin overheats components. Those electronics are supposed to be in an interior cabin behind panels, seats, or rear seat panels. But No!!!! Auto engineers deliberately play dumb, and poorly design things, in an effort to force you to take your vehicle to the stealership. The stealer then gives a cut of their profits to auto engineers.
Bad as GM fuel pumps are why dont they put removeable inspection covers for the fuel pumps on all of them.
She's wet on the inside ! haaaaa. Chrome can be used BTW sir. Wet in the box , her face was priceless
Power probe first. Then load it for integrity test, if you want. Why not just throw an amp clamp with your Pico around the fuel pump wire and scope it as it resets the breaker? That would answer the question immediately. Also, pick up some circuit breakers for your fuses. Save money and time. I'd also be careful about dead-heading a PWM fuel pump. Good way to blow some weak fuel lines. haha. Oh, I'll watch the video first next time. haha
Lmao. It's wet in the box!
very good Eric......all the best from Northern Ireland .
I was working at the plant that used to make all the GM computers now it's a shell of itself . the maintenance guy told me GM does not make sensors and modules any more. it's farmed out to whoever . explains the high failure rates
Steven Tenney reorganization
That spare should be part of the rotational schedule and dropping it every 6,000 miles would keep the mechanism from locking up.
I really appreciate you bro, i'm just a shade tree mechanic at best but i really like the way you make your videos, some of the best!
Great job Eric.
Eric please do a video explaining pcm up dates and software programming of newer vehicles. I have no idea what is involved with all that. What happens if you do not do software updates? Do you have to do them for the car to run right...??? Please please do a video. You are a very good mechanic and I know you know your stuff with this new technology, and old! You are the best of both worlds. So please help an old school guy like myself to understand these things. I am a mechanic myself but have never gotten involved with these high tech things and I find myself more and more falling behind!
Good video, as usual!
It looks like your customer will need a right tail light, when their state inspection is due.
Just saw a video where a 2018 F150 had a bad tail light from water leaking in, would not run and it cost the guy $6500.00 to repair , guess it had some modules inside it.
Do you have the ability to flash a new body control module in a 2005 chevy 1500?
Yes sir
I live in Georgia and i knew these people around here was full of it. I was told only a Chevy dealer had the program to flash it..Thanx.
Anyone with a j2534 interface device can do it easy
@@SouthMainAuto wonder how much that J2534 interface and software and the scanner ran you...
A shame Chevrolet has such a poor spare tire design and placement for a critical component. Great job troubleshooting!
These car companies have lost their minds with all the modules they put in cars these days. Windows, door locks, air bags, brakes, mirrors, HVAC, engine, transmission, lighting, fuel pumps, etc... all have their own modules! And they're just overcomplicated and failing all over the place. They make the cars harder to diagnose and more expensive to fix since the modules are marked way up!
Some Euro cars have OVEr 60 computers to make the car function
It is all sweeping us toward self-driving cars, why is no major country in the world making a stand against this.
That's the plan they want us all out of the repair work so they can get all the work.
Prediction cars will have a mandatory life span 10 years then the crusher.
That's the price we pay for fancy everywhere, all these neat electronics, the perfect balance between power/torque/fuel economy, and then throw in a little tightly intertwined ecosystem and planned obsolescence in for good measure. Oh yeah and you cant work on the car anymore
Ivan just changed one of these things on a GMC Acadia.
That comm is in a really bad place.
Thanks for the video. Having same issue in my 2010 sierra
Next up for engineers, a spare tire powered hoist to raise and lower the tire and also maintain proper air pressure for readiness at all times, complete with it's own control module of course. These should come on line soon after they unvail the blinker fluid control modules.
