Cadillac "Runs" on 2 CYLINDERS!?! (2010 SRX V6)
HTML-код
- Опубликовано: 12 июн 2024
- This poor Cadillac BARELY runs...apparently the entire front bank of cylinders has NO SPARK.
For some reason there's a new catalytic converter installed on the front bank too...as well as cam solenoids, sensors, and other parts...hmmmmm
ECM is setting some very specific circuit codes, so we have a good direction to start.
Can we get this Cadillac to run on all 6 cylinders without throwing any more parts at it?

How is it Ivan only has 205K subscribers??? This guy is amazing at what he does, let's spread the word and get him out there to more viewers.
Boggles my mind as well.
I agree
A lot of people don’t like Russians. Thanks to watching Rambo when they were kids.
@@chekelley6861I love Rambo, especially First Blood :)
@@PineHollowAutoDiagnostics haha! I was being a Smartass
Hold the start button for ten seconds with out brake on for ignition on !!!!
lol
hey we all learned 1 days
Not sure why GM wants you to hold it for 10 seconds for ign to come on. Learned it under smart key description and operations.
@@waqasazmat81 I just bought a car that needs key to start. LOL
A motorcycle I can see a push button being used. But that means an electronic lock for steering wheel. Unless you use a key to unlock it, then put key in pocket and start engine.
@@robertsmith2956 I never have to worry about locking my smart key in the car, I just keep it clipped to my belt or in my pocket. Of course I own a Toyota so I don't worry about the associated parts failing, I mean they can but it's rare, the console shifter already requires an electric interlock that rarely ever fails on any brand. And the Toyota system (I don't know how GM operates because I won't own a modern GM) reduces wear and tear on the key fob, I only have to touch the door handle to lock or unlock the car. As far as run position goes it's just a tap of the button without a foot on the brake.
Paused at 3:20 I'm not sure if your aware of this Ivan. But ALL GM's with push button start, you have to hold the start button for 5 seconds to get the switch into run position.
Nice work finding that broken wire. They are not always so easy to find. But it never ceases to amaze me when a customer just want's one thing addressed, when the car has a laundry list of problems still.
The first time I ran into this with a push button start, I was like a monkey working on a math problem... RUclips for the win LOL.
@@HouseCallAutoRepair I actually stumbled onto this a long time ago. I was just pushing the button repeatedly like a circus monkey, when my latex glove got pinched in the button hole. lol
Here is a quick tip i picked up from South Main Auto, wrap the tape around a small socket and you now have a small roll of tape
Free-tip Friday on a Thursday.
Yes as a Truck technician that's the best small roll of Tape 🇺🇸👍
the plastic spool from scotch tape roll works for me. I don't loose the strip at the end like the cardboard it comes on does.
One of the hardest things to find when I was an aircraft electrician was a wire that had just enough strands to show continuity but could not carry a load. In those situations a simple test light setup was often more helpful than the fancy test equipment. The only thing more frustrating was when there was intermittent contact. Often a problem would occur under certain g-loads and work fine when the wing flexed and contact was restored. I've seen several of your videos where you've had to deal with similar situations with the cars you work on. Your patience and ability to follow some complex and often erroneous wiring diagrams is commendable. Thoroughly enjoy your channel.
I didn't realize that Cadillac shipped a 2-STROKE version of the 3.0L V6 🤣
The oil mix is 50:1 not 5:1!!
I wanted to see if it smoke as much using all 6 cylinders.
Ivan was doing burnouts with the Caddy and he doesn't know it yet LOL
One thing about a good mechanic is we may not know everything but we are willing to learn!
Someone told the owner to put a cat in there to keep the rodents away....
Great upload & investigative diagnosis Ivan, thanks.
Hold the ignition button down without touching the brake for ten seconds. That'll put it in service mode
Yes why in Jesus name did he not look that up!
@Evolvedmindz1 I had a Chevy bolt ev last week that when I ran the front view camera calibration on the autel it said it wasn't supported, I then hooked up gds2 and it did the same thing. There's no engine of course and I tried to run it koeo and in service mode and any other mode in between lol. Turns out it's just a software glitch coz it was actually in calibration mode I just needed to drive it lol. I got frustrated and passed it on to another tech coz I was in the middle of a 22 crv main harness swap. I was pulled off that job to do a "quick" calibration. Ya right it's never quick lol. It's just gm ain't caught up with the released versions of the program to make it work like it should so if ya'll run across that just drive the dang thing😅 I've worked on cars with 53 miles on em and they have me strip them down to the unibody so the structural techs can go at it, two months later I gotta come back and reassemble the whole car and I'm a mobile tech so it can get interesting to say the least
@@autotek7930Same for 2016 Cadillac ATS so you get into Accessory mode to be able to move shifter without engine running.
@85rx7se any push button gm is this way. It's just the ev stuff hasn't caught up software or service info wise
I learn a ton from you and I'm an experienced tech of 20 years. Thank you for teaching us.
Thank you for trying to improve yourself! My mate has a farm and has had problems with various equipment that Oem service techs can’t fix … he pays good money for no reason… then begs me to come out to fix the the problem… I am an accountant. I ask him the problem and look up the interweb for 10 minutes and isolate the problem in 10 minutes. Mainly Polaris problems… why can’t techs do this?
If I could play devil's advocate here for a minute: I bet the customer drove around for a long time with a misfire and killed that cat! I try not to jump to conclusions when I see new parts because you don't know the whole back story. People ignore things for a long time and then end up having to get all sorts of repairs done all at once and then you look at it and think that somebody ripped them off which they might have but there's also the possibility that somebody was ignoring problems until the car literally wouldn't drive anymore......
Good info. !!! He had problem a long time. Could have been lots of raw gas.
Doubtful, most owners aren't going to replace a very expensive catalytic converter to fix a misfire if the shop tells them there is ZERO chance that it is the problem. AND what shop with any moral character would replace a cat on a vehicle that is still running on 3 of 6 cylinders, even if the cat was known bad? Any shop with morals and dignity would advise the customer that doing so could ruin the very expensive new converter. The smoke show is oil that will coke in the converter reducing its lifespan. A shop that imagined that a 'plugged' cat could stop the whole bank from running is my only conceivable guess.
@@truracer20 thanks
@@truracer20 does the gas ruin the rings or cylinder walls?
@@peetky8645 That would be my guess, that the unburnt gas has rinsed away the oil film on the rings and walls leading to excessive blow-by, along with a huge amount of raw gas being dumped into the cat because it's spewed out the exhaust valves.
Great Diag, Thanks for Sharing! Sometimes I feel like charging by the amount of AllData tabs I have open😂
GM used to have the slogan "GM: Mark of Excellence".
Makes me want to hurry out and buy a Caddy !
🤣
Another informative diag ❤
Excellent job testing Ivan. Love your home made test lights.
I’m wondering if the car was ever in an accident and the harness was not put in the retainer at the fans properly? Great diagnostic and repair!! It’s a junkillac!!!Thanks Ivan!!!
IVAN, I can not get enough joy and pleasure of watching and learning from you thanku for ur time by showing ur approach and thought process how to fix such aproblem and love the test light method that u used brilliant indeed cheeeeeers from Canada .
Great job again Ivan! I really appreciate your thoroughness with these problem vehicles! 😃👍!
Usually you just press the start button twice without pressing the brake. That will turn the ignition on without starting the engine on pretty much every car with a push to start button. Some cars you would just press once, and pressing and holding would get you accessory. It's pretty much going to be one of those combinations.
I got to 10:07 and you explained in addition to the entire bank #5 was also not running. Now if it were a 966 and it was running on one bank it WOULD be 2 cylinders. GREAT VIDEO!
Very cool diagnosis process instead of power probe power you sent supplied power through 5 amp light then a test light on the other end to see a dim light and a wiggle test to nail the failure point. Hopefully the guy doesn’t have two dead cats now! Fun stuff and a cool car! Well done Ivan.
Hey I have a power probe and a similar issue with bank 2 not working. How could a power probe be used to diagnose this? Thanks!
Power Probe is wayyy overrated 😂
I will never complain about no room under my hood after seeing that caddy. LOL
You always do great work. Thank you
This is why you can't just throw parts at a problem, it may have worked back in the old days when parts were cheap, not anymore. There was probably gas in the oil burning off and he more than likely drove more than ten miles, the cat is no doubt compromised and who knows what happened to the cam sensor. Drive it to the junkyard. But I always enjoy watching Ivan methodically peel back the onion, 90% detective work and 10% nuts&bolts.
Man how can I find mechanic that do diagnostic properly just like he does!! I love your work man even though I don’t know a lot of stuff that you show us
The wizard does it again folks. Great diag as usual and fantastic approach to systematically eliminating variables. That car had the James Bond smoke screen built in. I owned one of these and glad I tossed it when I did.
First in😊. I spray my tires and wheel wells every evening with peppermint oil and no more mice getting into vehicles since I started this a couple years ago.
I wonder if that would work on squirrels also.
Wow spraying the wheels every night is true dedication! 😅
I feed the feral cats outside, and they bring proof they keep my wires safe. Although one had her kittens on my engine. Didn't get my car back for 3 weeks. Pop the hood, and the cute little buggers scamper back into the harness and hoses. Thought there were two, but then spotted a 3rd one.
There are five feral cats in my back yard that I feed. Never had a problem with mice. I have 4 cars and 6 vintage motorcycles. A mouse could cause significant damage.
You are a GREAT MECHANIC!!! No doubt about it!
Thank you very much Ivan
It’s wonderful to see honesty and integrity in your work! Your greatest asset is your persistence to find the solution to a problem. You understand that there always is a solution and you’re willing to find without screwing your customers. If you become a public corporation, I’ll be happy to invest! Congratulations for your success!
Thanks for the video Ivan.
Here in the UK I have a little Vauxhall Corsa, a GM product that recently developed a misfire on number two cylinder at low rpm, when you rev the engine the misfire goes away, if you let it idle and misfire for more than about 20 sec it will shutdown the injector on that cylinder to protect the engine and cat, sounds to me like the Cadillac could do with something similar! Thanks Ivan for all your videos I have learned a lot, mostly to take stock of the problem and not jumping to conclusions and start tearing things apart before proper investigation.
Fine job as always ivan
Better than your average technician.
That's an insult. Ivan is an engineer. A talent.
you are amazing you are getting better as i continue to watch your series and i did thank that was possible that smoke show was impressive the police would have a problem pulling you over because they could not find you
The shop was so close to figuring this out when they jumped power and got it running. Just couldn't find where the wiring failure was.
There was no doubt in my mind they were going to say you can fix the wire,. 😙
Nice work well diagnosed thanks 😊
Thanks Ivan!
You are SO RIGHT about the drawings! It was the same way in my line of work - and most guys had some sort of aversion to using the drawings - which really limited their success. Yes, a drawing can be wrong some times - but I would always mark up a hard copy and get to the right person for updating. It really helped me the next time I worked on that equipment. Funny that the ECM monitors the hot wire that way - I incorrectly figured the coil primary was fed by a fuse, and the ECM monitored the other coil wire for voltage when it was not being pulled low. I always make the wrong assumption!
I deleted my comments about the 2 cylinder Caddy.
Maybe at 81 years old I was in an "instant gratification mode"!
Good job on the 2006 Accord 6 cylinder valve adjustment video.
I have a 2007 Accord V6 with about 110K miles. Runs great & extremely reliable.
Please never delete your comments, just respond. Deleting comments wastes time of people who took time to respond 😊
Unreal the owner was dooooooped from shops throwing parts at the cati, even the dealer. Great catch finding the broken wire just by understanding how the ECM and coils are receiving power.
Wow! A V6 with access to all 6 coils without having to take off the intake plenum.
Something you could have taken for granted 20 years ago that such simple parts would never require pulling a manifold...
an intern snuck the plans through on a weekend
Good job hunting down the short in the wire. What a pain after all that work and still having issues. Every time someone I know buys a project that only needs a sensor, or a module it ends this way. Spending days to find out the pistons are bad, or trans ☺.
That's crazy. Well, wiring problems can be like that. Good fix Ivan! Hope no one calls the Fire Dept when this vehicle drives by!
Hey Ivan! I also have a Thinktool Pros, bought one a few months back since it seems to work so well for you, love it. I don't believe I've ever seen the CAN designations on the Smart Scan. Is this only on newer cars? Mine is an '06 and I've worked on an '07.
great job
Good job 👍
Great diagnosis as always, Ivan! The owner fuel-washed the rings on the front bank. 😂
GM's push button start vehicles are different from all others, you hold the start button for 10 seconds to get into run mode. Triple horn honk is to remind that keys were left in the vehicle.
Wow good job amigo
Great video with morning coffee
Besides the short roll of tape, something to add to the fix box is some inner tube rubber and a razor knife. The inner tube cut to a patch strip, put a pair of slits about 1/2" apart near one end, thread in a zip tie(s), wrap the rubbing harness with the non-zipped end, rolling, and fasten the zip ties, to make a rubber buffer between harness and sharp edges. Also, keep some hockey tape on hand, it is the black cloth tape from the sporting goods supplier. Works great on harness looming.
Ivan, this is why you are busy... LOGICAL REPAIRS! Good Job! Gotta love GM Trash.
007 would of been jealous of that smoke screen🤣🤣
Great diag again Ivan👍 you’ve probably seen how Eric from south main handles tight spaces and electrical tape he simply wraps some around a 10mm socket and bobs your uncle😂 great tip but I’m assuming you’ve already seen this trick
Hey Ivan good video, after watching it something dawned on me. You mentioned in the video you have to start the engine to get the accessories to turn on? Did you try to press the start button twice only and not put your foot on the brake pedal? I assumed that is the way to get the accessories to turn on only and not the engine. I just went outside and tried it on my neighbors 2023 Chevy Trax and that car was able to do that. I am sure this is past tense now but I would recommend trying this on your next GM vehicle. Good luck and thanks for the videos:) Udachi!
Great job, Ivan, I do think the actuator should have been fixed.
All data to the win.. 70% of Research time or.. Don't your vehicle for diagnosis!.. good stuff!
I drove an LF1 powered CTS when it was new. Those engines are a riot. 270 hp @ 7,000 rpm out of a 3L. Of course they didn't stand the test of time but when they were new, pretty fun.
I'm going to let you in on a big secret. In 2010, GM cars were key on engine off by pressing the push button, then waiting a second and pushing it again. Then after about half a year towards 2011, they changed the style to holding the button for 5 seconds
good video -- you = good soldier
Nice job!
Winner winner
Asian dinner 😁
Diag master🎓👍
Masterclass in troubleshooting.
Agreed, Service data subscriptions are mandatory. Being mobile and working on a little of everything, I wouldn't survive a day without my prodemand subscription.
Your a master tech you no how to repair via cars computer. Most shops can't do it.
well done
What someone else commented you have to press and hold the start button until the ignition comes on. Otherwise you are not in accessory mode.
Take a look at the TS101 iron, bet you’ll be a fan. Hit a tool company up & I bet they send you one. Great videos THANK YOU & good job GM 🙄 once again
The best thing since sliced bread,,had me giggle out loud 😂😂😂
those remote soldering irons are great for outside work
For tight places, use a 10mm socket and roll some tape around it and use as a dispenser. Thanks to SMA for that tip.
Awesome
Your the man I van
Excellent Eric Excellent
I actually didn't have to call Eric for help on this one 😂
Piece of mind knowing you have excellent backup to turn to
The rat wasn't OEM, the wire routing was. That is why they missed it. 😜
I'm definitely going to get a 1month subscription. My buick heat just stopped working.
Making my lights so I can see if wire can handle current. Already ordered some Y plugs. Got a dodge, and ford that will give the test lights a workout.
Great fix my friend. I have one question. How do you like your catalytic convertor cooked. Rare or well done.?
Cherry red
Ivan: There's no way you can get a crimp tool down there.
Me: Hold my beer.
Also me: Run a new wire.
Mechanics will never see another mechanic's milspec butt connector crimped properly because it won't fail. But they will see the garbage butt connectors from Walmart crimped with a $5 non-ratcheting crimper because they're failing and bringing the car back into the shop. It's called survivorship bias. And it leads to wrong conclusions about efficacy and the right thing to do. Go read the Wikipedia article on this. You'll get a laugh about what happened in WWII. The reason you never see Ivan's solder joints failing is because he usually gets these cars when they're closer to the crusher than new. But take another vehicle that people usually keep longer like a boat or airplane or a vehicle that gets abused and it's a different story. If you don't believe me, ask yourself why OEMs always crimp terminals on never solder. It's not because they can't invent a machine to do it at scale. I will solder some wires, but it's mostly smaller wire like signal wire because it's easy to provide strain relief across the solder joint.
Ive never seen a proper butt splice repair fail, i have fixed many failed solder splice repairs due to fracture in a high vibration, high temp change location. I used quality butt splices to install relays and circuits into my headlamp harness to keep low beams on with high beams about 13 years ago, never have any problems with them.
I love to read the comments and how everybody knows everything so often about these vehicles. But when you are out in the field and doing it and freezing your nuts off and it's raining and all of the above it's easy to say , right
eric O, has his trick w/tape for tight spots, you probably have seen. he uses an 10mm socket and wraps tape around it for those difficult to reach areas. it's a bit more comfortable and effective than the almost empty tape roll. just an FYi
But my 10MM sockets keep running away!
Hey Ivan, did you figure out KOEO yet? From ignition off, hold the start button down until the dash lights up, maybe 5 seconds or so.
Blame the car for harness routing, but you can also blame the car for having the BCM function setup to monitor that +12 volt power line to the ignition coils and provide a fail code. That's what narrowed the diagnosis down to the open wire.
To turn on the ignition, press and hold the start button for 10 seconds. I think you found that out on a Cruze you worked on.
Good work Ivan, by the way, Where is your safety belt in this car when you are making test drive,Ivan? 🤔 😮😮
I remember on the older trucks you couldn’t clear active codes
The triple beep is the "Hey dummy, you left your keys in the car". It doesn't have any sensor to know that you *didn't* step out of the car.
I thought he just pushed a button. I guess you mean the fob.
@@lvsqcsl Chevy has a feature where when the car is shutdown, and the driver's door opens and closes, the car will check for the fob inside the car. If it finds it, it will triple beep and unlock the car. The car is assuming the driver has stepped out, leaving the fob behind.
A lot of clueless drivers out there 😅
@@PineHollowAutoDiagnostics Truth!
Great diagnostic sequence, Ivan! Cylinder 5 coil disconnected is a rookie mistake :-) Thank God you didn't have to dive further into that can of worms!
PS: A couple of representatives of the sex industry are trying to get your viewers attention.
Did you guys check the engine oil level? Did fuel makesl its way into the crankcase? Perhaps an oil change is needed before customer drives it home?
Of course. Oil was actually remarkably clean and fresh... Shop must have just changed it lol
Hold push button for 10 sec for the ignition to remain on. On some vehicles if held for 5 sec ignition will eventually time out.
Wauw all that work for nothing , good diagnose Ivan 💪🏻
All that good work truly didn't seem appreciated by the customer. That's like being on the 1 yard line, first and goal, then just walking off the field with a loss. How dumb. What a cheapo. Great job on your part Ivan
I would imagine that as this wire wore through it would give an increasing rate of misfires. If the owner just ignored it and kept powering through that would feed unburnt fuel through the cat, until it failed. Thus the cat may have been throwing codes and needed replacement as a secondary failure to the ignition problem. It is one of those reasons why problems should be fixed and not ignored.
Would changing the diluted engine oil stop the smoke?
An oil change with FHS Smokeless Motor Oil will cure that smoking. Pretty expensive though.
Hey, that's the corner used car lot trick...
I saw one of your videos lately of you wearing the seat belt, now not so much, thought you noticed all the blinking lights on the dash, like the seat belt one, COME ON IVAN
Not sure about the Caddy but my 21 Honda press the start button twice for ignition but don't press the brake
What's the customer's beef? Lots of cars, motorcycles and even trikes run on three cylinders!😂 GM sure stuffed that harness between a rock and a hard place. I have one of those soldering pencils too. I power mine with a motorcycle battery and special adapter. Lastly, from running on only three cylinders and dumping fuel into the dead ones, I'm thinking there may be gasoline in the crankcase along with the oil, so the oil level is too high. Do an oil change. That might fix the smoke problem.
Those GM vvt solenoids and catalytic converters have high failure rates , I doubt they were changed to remedy ignition coli circuit codes
The smoking problem may be indicative of gasoline dilution of the engine oil. An oil change might have improved this condition, perhaps substantially.
I see I’m not the only one yelling hold the button down as long as a Volvo
😂
Nice video and diagnosis. I guess the Mosquito population around State College will be decimated if the customer keeps driving the car like that. 🤣🤣
