How To Troubleshoot And Program A Cat ECM
HTML-код
- Опубликовано: 19 июн 2016
- Have a Cat Diesel Engine and suspect that the ECM is going out or may be causing problems? The Electronic Control Module is the brain of the engine and is a common failure of these engines. Watch this video to gain the information to go over basic troubleshooting and programming of the ECM. Did this video help you save time or money? @AdeptApe on Venmo or AdeptApe@yahoo.com on PayPal for donations, thank you so much for supporting the channel!
Just installed one on a school buss, man that was a different animal, the school decided to sell it without the old ecm, or the bolts or spacers, or grommets, so pretty much manufacturing all the components to mount it. You have just enough room to get one arm in the compartment underneath the bus. My hats off to the people who work on them.
Thank you for great info. Your explanations of how this work are great! THANK YOU!
Am an Auto Electrician been in the industry for 3 years now and really you are good boss thumbs up..
Hello there. Very informative video!
I purchased a caterpillar 525B that took a lot of damage and is being scrapped. Although it’s a lost cause…Most of the electronics are still intact and undamaged. I have a bit of experience with dealing with ECM‘s, I’ve repaired dozens of car and truck ECM’s at the component level… However I’ve never dealt with anything from an huge industrial motor. I buy and repair pallet loads of industrial equipment… mostly as a hobby and supplemental income. But usually stuff like CNC machines, servo drives, motor controls, stuff like that. Never dealt with these massive engines and all of their electronics goodies.
I have a humble troubleshooting lab, and will check everything to the best of my ability. And then pass it on to someone who needs it. Maybe I’ll be able to trade it for something interesting… Who knows.
The machine I Purchased is going to be scrapped this week or next… it was in like new condition with low hours on it when it took a tumble off of a large embankment and did more damage than it was worth repairing. It belonged to a large construction company and I bought it directly from the owner after his insurance was settled.
all of the electronics and wiring were completely undamaged in the fall. Some of the electronics had been disconnected and a few potential buyers had poked around loosening some connections and possibly removed a few sensors or modules. I’m not sure how much is missing, but the main ECM is still there. So I would assume they would’ve taken that if they were going to take anything.
My ecm isnt on the side of the engine like shown in your video. It’s directly under the driver seat fastened to the bottom of the cab on the outside. I was curious if it’s common for them to have different locations like this? And how the heck to find all of the other hidden electronics, modules, or sensors. I want to remove anything useful or valuable before it is scrapped.
Some of the stuff is really hidden deep and hard to find. I’ll fallow the path of the wires I can see, but I’m worried some have possibly been removed… or I’ll miss some valuable module or parts. Considering a few potential buyers loosened some of the connections and possibly moved or removed things… I just want to make sure I find everything.
I Tried to find a schematic or diagram online showing the location of all the modules and sensors that I’ll be removing but no luck so far. The model number of mine is 172-9389-01
Thanks for the video and thanks for your time.
Appreciate your videos. I am a Ex CAT/Cummins mechanic retired from a pete dealer. The strangest ecm failure I encounterd was a 550 Acert in a 379 pete. brand new off the piggy back tk.This engine sounded like it had a High lift gasser cam in it was hilarious belching smoke and loping like mad.. ! .Had et plugged into it and it was throwing every code you could think of from cam/crank timing codes to inj pulse width.basically freaking out.Tapped on the ECM case with a rubber mallet ran perfect.flashed new ecm all is well.Did download on bad one for warranty. Cat called service manager week later.Turned out to be a bad solder joint on the hard board. Was a MXS motor and they had over 50 of them that got out into production giving everyone fits on diagnostic side
Great videos. Thanks for posting.
GREAT CHANNEL BECAUSE IT IS REAL SCHOOL FOR CATERPILLAR
Great video very informative as usual
Hey - thanks for all the time you take to posts the videos - they are very helpful. I have a question.... I have a 3126 from a 99 Kenworth that has all 6 injector codes... 1-11, 2-11 etc... It looks like the ECM is bad. My question is - do I need to look for something in the injectors or the injector harness before I plug a new computer into this thing? Like a ground fault to power or something like that? I dont want to smoke a new ECM if I have a harness or injector issue. Do they just fail or is there an underlying cause? Thanks in advance.
Jon
very help full video many thanks for you chief
I'm 48, and so far in top physical condition. I had a cabinet shop, have done mostly kitchens, and lots of rehabs. As an entrepreneur I'm looking at starting a road service and truck towing business. thanks
I think a mobile service truck is a pretty lucrative way to make money, if you can specialize even better. RVs for instance are always breaking down and word of mouth spreads quickly. Could make some good money doing that.
Also fixing old Mercedes Benz with over 100,000 miles is also a ludicrous way to make money, if you can specialize in low end communities and slums you can make a killing fixing high mileage Benz, Bmw, Cadillac Escalades.
Please show us how to download the software and program engine control of generators like:caterpillar,cuminse and etc.
Thank you
can you teach how to use the eletronic comunicator adpter for diagnósting?
Hi Adeot Ape, I'm having some trouble with a C9 generator. It has a number of strange intermittant faults, the first being it wouldn't take full load. I've tried running the cylinder cutout test in ET multiple times (amongst other tests}, it passed once but stops the test consistantly while testing unit #3 (the one time it passed, all injectors were "questionable"). The reason ET gives is "a change in engine load or speed, which is not allowed". This is not actually happening as each time I tested it the generator was not connected to any load whatsoever. The ECM also frequently throws an intermittant "Inlet air heater relay current high" code as well. Have you seen anything like this before, and do you suspect this may be the ECM on its way out? I've also had it lose connection to ET randomly a couple of times, with no bumps or change of any kind to the wiring/adapter leading up to the ECM.
As a side note I disconnected one speed sensor at a time to check them before starting it back up (it ran fine with no difference to the tests), but to my surprise the ECM didn't seem to care at all that it was missing a speed sensor, let alone throw a code or any sort of warning.
Hello Adept Ape, where do I buy the ECM software to flash a bulldozer Caterpillar 320D?
I was messing behind the ignition area. I shorted something out and now the truck starts to turn over but it won’t fire..
I can’t find any ecm fuses around the batteries anywhere. And the ones in the kick panel are all good.... any idea where I could find the battery to ecm fuse?
Not under the dash/ not on the fire wall / and not on the battery box... suggestions?
Big YES common cat issue
helo man. could you assist us? may you help us? we dont have software that analyzer the offroad truck power train tool , transmission analyzer 3. have you any idea where we can download it?
Great Job
Is there a way to jump a new (reman) ECM to a truck C7 engine to bypass the installed ECM to see if the ECM is the problem?
This is one of the worse jobs on ANY vehicle : Troubleshooting ECM, harness and connectors...and most of the times the problems are intermittent and hard to reproduce when u want it to.
I had an ECM die on me once at 140k on a crappy 1996 Eclipse. Darn thing made of kinds of noise and clicking sounds...good thing it did, it just made the whole ordeal a whole lot easier for me. Do HD trucks come with a bunch of body modules(smaller ecm's) like new cars too ? Keep the videos coming...i don't work on HD trucks but i like them a lot. 👍
Forgot to add: Yup, heat KILLS A LOT of electric/electronic. components...the Eclipse ECU gets pretty hot and it gets no air flow(confined to a TIGHT space next to the radiator and getting cozy with the battery, acid bath and fumes, anyone ?lol).
The newer the truck the more modules it has. The engine has one as well as the ABS, sometimes a dash or cab module, body control, and transmission of it has an automatic, are the more common truck ones.
What are the types of ECM used in the Heavy Equipment Machineries such as Caterpillar
Thank you man greet video .do you have the schematic for the wire between et and Ecm I want to make contact with et and Ecm at home I have c18 set on pm200 cold planer
Hi, is it possible to reprogram the ECM in order to reduce the engine power?
I have a C7 in a 2007 Motorhome. It keeps giving me a check engine light. I took it to the local diesel repair shop and he said he thinks it's the ECM. How can I have the ECM checked? Is there a good place to take it in Salt Lake City that could check it?
Thanks for the info
Do you happen to know what typically fails at a component level inside the ECM? I have a 3126b ECM open on the bench and don't see anything obvious with my multimeter.. what is a good resource for the 70 pin connectors to build a bench harness?
can you explaine what is interlock code sir ??
which cat communications adapter do i need to communicate with a 2000 Pete with a 3406e sn2ws38662 i have cat et but i see that there are several adapters out there and the 2 is cheaper than the 3 but which do i need.
I have a 2001 Thomas saf-t liner with a cat 3126. It turns over but won’t start. We weren’t getting any power on the harness spot on pin #70. Is pin 70 ignition with key in on position on all cat ecm? And if so what should I try next?
Is it possible , losing power and boost after disconnecting batteries for truck repair. They were disconnected 6 hours on 13 years old NXS acert
Hi buddy can you recomende a good scanner for diagnositics , thank you ...
Im facing a big issue of trouble shooting a c32 cat generator.
It is deluting diesel in engine oil. With in 1 to 2hrs while loaded it mix 10 to15 liters of diesel in oil sump. Checked fuel trans pump for leak trace nothing after replacing all injector O-rings but still facing the same issues. Exhaust manifold glowing red in the part of cylinder five and six while at fullload.
Hi, Ape first I like to thank you for your excellent video you provided to us and even now with special effect I love it lol. Question there's any way to reset or erase the old code that it's on the ECM? After putting the ET to trouble shoot the miss according to the mechanic cylinder #3 was bad I replace it my self thanks to one of your video by the way I have a Cat 3126, well 3weeks after its star miss again this time I retrieved the code just like you said on the video with the cruise control and it give me the same code again 73, what should I do now?
Sorry I missed this comment, somehow it didn't get sent to my account for notification. Well if you are having the same code for the same cylinder you most likely have a problem with the wiring or the electrical connector going to the injector itself. I hope you got it fixed by now.
Have a 98 GMC topkick 3126.
Runs fine but once it warms up while driving it stahls shutters and shakes has no power can only do 40mph. Or it will just cut off and die out. Its getting plenty of clean fuel. Don't have a scanner, tried that check engine flashing light trick saw from jcook007fix channel. And got 72 , 73, 74,. Could this possibly be the ECM?
How hard is it to take the moter out of a 2000 Sterling C12 and put it in a 2000 379 Peterbuilt is it compatible?? Please let me know
Thanks
Tnx man. you saved me a lot
You are welcome. I know it can be daunting if your truck isn't running right.
the miles on ecm stays the same after swap? what if u have an fresh overhaul, do miles on ecm need to be changed to 0 ?
Great video!
pls can u tell me who i can connect the tools cat et with cat C7engine but cannot reaading what the prb, pls
No data or CE light at the six pin connector on my sterling 3126b- cat
I have a cat 6NZ and recently job I have done was manifold and the guy did a lot of welding trying to pull out broken studs and since that day I have faulty sensors and replaced it but still showing up and truck shut down while driving or idle no matter what circumstance do you think this is a ECM problem? And I already change and check all wiring. I don’t know what else to check
Where is your shop located at?
Why don't they have an outer iron plate with a jacket bolted down on top of the ECM? You tube in chilled anti-freeze from the center of the plate into the jacket, and cycle out the heated anti-freeze from the edges. What would be wrong with a mini-radiator system bolted down and around the ECM?
love your videos anything i can learn is great, i have a c 12 and its cutting out here and there first on a pull then even at an idle, its like the power cuts to the ecm or something , but the guages dont move and thers never a check engine light, checked all wires and found no bad spots or fub throughs, did find one rub through at the plug going in the the rocker for the injecters , but could"t get it to cut out to se if it was the cure , guess will find out with work monday, iseems to be when engine is over normal op temp
Suppose in a fleet where the trucks have sequential S/N's and one truck's ECM is possibly bad and no CAT ET in sight - for troubleshooting, it should be OK to remove a known good ECM from one of the properly functioning trucks, install it in place of the bad one, and test - right? Even with different injector trim codes, the truck with the bad ECM would now operate satisfactorily with the known good ECM - right?
+Chad Jessup Yeah that would work to see if it's the ECM. The truck would run fine like that.
Adept Ape hello.could you inbox me please. i have questions about my c15 engine
Ermink@ymail.com
I had some wiring issues due to those zip ties on the ecm connector. Some would be so tight that wires shorted together or the plastic would cut the wires. Ive also replaced several ecms on the c15s. All were the same fault. The sensor wire for the intake actuator sensor (jake brake pressure?) was battery voltage instead of 5v sense. Wiring was fine. Replaced ecms and sensor and were good to go. But had one come back with same fault 3 years later. What gives? Same fault trouble shoot and ecm is outputing battery instead of 5v sense wire.
+Alex Alanis The IVA oil pressure sensor, the one on the valve cover base by the turbo does go out all the time on ACERT engines, but I've never seen it read battery voltage. Sounds like you have some gremlins on that truck.
Hi Ape I was thinking if you have any advice for a middle aged guy who is looking for a career switch. I have automotive training but I've worked mainly as General Contractor for the past 20 years. I planned on starting a diesel program in that fall. PS. I'm very grateful for your videos and hope your answers will help others in the same predicament.
Hmmmmm, it's a hard field to start when your older. I'm not super old but if I was changing careers and was middle aged I would probably look into something that would be slightly less physical. What did you do as a GC? I guess it depends on how old you are? I've thought about in another life I might have been in HVAC or maybe Alternative Energy. They seem like interesting subjects to get into, but I'm doing well where I'm at. With your GC background, have you thought about being a handyman working for a property owner or something, my neighbor does that, he is in his 70's and makes good money doing it.
I have 2007 motorhome with a C7. The light bar was replaced and it corrected the guage problem that I was having but the odometer was incorrect. Can this problem be corrected?
So what about a truck with the injector current faults but still runs just misses intermitenly?
Hey there, hoping maybe you could help me out. Ive replaced all my injectors with reman units on my nxs acert. Trying to install the trim files, files go in fine but as soon as key is turned off the trim files go back to old files. Have 12v on 70 with key on, and 12 volts constant on 2 other pins (according to diagram). Have you ever heard of this?
+Big Bore Well that is a new one on me. I've seen ECMs lose trim files and, but usually they go to unprogrammed. Do you notice a difference in the engine running with them incorrectly programmed? If not I wouldn't worry about it. I wouldn't think a battery problem would cause it though, as some trucks have battery disconnect switches and that doesn't seem to affect them.
How about an07 c13 burner eng. LEE ser. # in an Oshkosh. Eng cranks no start no codes ! Guages sweep speedo says lost eng communication! Changed eng harness have pwr n grounds at P1 conn still crank no start installed test ecm same thing !! ???
Excellent vedio very nice job it's my best job
Do you need to replace an ecm on a C15 Acert when you change it over to a single turbo with 16:1 compression pistons? My motor is a bxs ecm part number 10r4994? Can this ecm be flash and reprogrammed?
Part number 10r4094
I have a question my truck will drive great but at times just looses engine power I be going down interestate at 70 mph the truck just shut off I make it to side of road turn key off wait a bit I will here a click inside my truck. My truck is a 2000 GMC c6500 with 3126 I replaced iap valve by heiu pump really could use some help
I have another puzzle for you. I have a 3406e 5ek I have replaced injectors , injector harness and ecm. The engine runs very strong then it will start popping and blowing white smoke. This comes and goes quite frequently. I'm going to try the engine harness next unless you have another suggestion. Oh I took the exhaust manifold off and it's all 6 cylinders.
+Alice Stoneking Hmmmmm, are you getting a check engine light? What is your fuel pressure when it is acting up?
May sound silly just check fuel primer (they can pull air through
Hi! i like your video very informative, do you also do insite cummins engine, just need to know more about it. thanks!
Hey I was wondering how I would be able to run a 2001 cat 3126 on an engine stand.. how would I go about powering up the ecm to get the engine running? I have a 70 pin connector with wires attached but they are all cut since it was pulled out of a truck
+crimson22s You would just need a wiring diagram. Then just run the powers and grounds to the P1 connector. You'll also need to wire in a throttle pedal for rpm control. Should be all you need.
amazing videos Ape !.. a quick question... how do you diagnose an old 3406E without expensive equipment or software??... what ET version and data link would you recommend for the job?..
Diagnose what exactly? Do you have a check engine or just have low power?
I'll be doing a video in the next couple days about troubleshooting check engine lights and codes, so make sure you subscribe.
I would like to do the cylinders cut to check the injectors... I dont have the check engine light and did the code test with the cruse control method which gave me the 5 5 code.... engine lacks power ...is a 2WS rated at 475 HP... I am subscribed already.. ;)
+HENRY VILLATE Well unfortunately I don't know of a cheap way to do a cylinder cutout test. If you are really dedicated you could make a toggle switch setup running to injector harness and switch them off, but I think it would be cheaper to just have a Dealer do a cutout test for you.

Muito bom meu amigo...
Just got done replacing two ECMs on 2 different trucks both trucks are 2004 KW T800 with C15 acert BXS one truck having 13826 hrs the other truck having 13914 hrs with in 2 weeks. Trucks just 1 S/N apart. Same code all injectors current high plus a couple of AIV. Thought it was strange
Hey any rough idea of how much the software cost?
sir,
I have 1300 ED series (ECM ) Module wiring digram need.
Thanks.
greetings from Venezuela, exactly that happens to a 325d excavator, initially it starts at high rpm lasts about a minute on and starts throwing all the injectors as a fault code and does not turn on anymore, the case was that we looked for another ECM and just connected it All the injectors are already out and it does not make the injector recognition sound. My question is, could it be that a used computer also has to be programmed? We don't know what to do anymore.
How can we know the ECM fits for engine truck or generator engines ???
Can u tell me if i can take out a C15 and install a 3406e ,do i have to have a adapter for the ecm?
Hi all. i have a Cat C4.4 Diesel engine on a wood chipper, The unit has an LCD display. It runs ok for about 20 minutes then suddenly the LCD display goes blank and the engine looses power completely, it shakes while powering down. After that i can press reset on the Control panel near the LCD, the LCD comes back on as normal and i can start the engine normally. It does the same thing after approx. 20 minutes. Any suggestions? Possibly ECM heating up? Bad relay? Ive checked all the wiring harnesses. We did have a problem with the Ignition cylinder harness, but that was fixed. Please Help!!!!
Make sure you have decent Earth from block chassis and possibly start back to the battery
very helpful
Thank you for the very kind words.
I live in Nicaragua, Central America, I want u guys help, can I use a Cat 317-7485 Communication Adapter 3 on a D6M 1996
Cat et how to change 5 volt to 7 volt lift valve power et setting please sir
I have a question, can a injector driver go out or work intermittently in an ecm without throwing a code?
Usually it will throw a controller code or whatever for ALL injectors. If its a wiring issue it'll it'll only 2 sets of injector codes. Sometimes it'll be interminet and then eventually all together the driver will go out. VERY common on a rv and buss due to poor air flow management
No check e. And no certain rpm but mostly from about 5% to 75% throttle. The filters are staying full but it does act like it's getting air but it comes and goes and doesn't die. Psi?
+Alice Stoneking For a 5EK, I'd have to look up the spec on the PSI, but I think they should be around 60 psi, I can check on Monday.
I'm going from working as a fleet mechanic to a dealership. At a dealer if you own your own laptop will they put oem software on your laptop or do only the company owned laptops get used? I know it will vary from company to company.
+asavage1576 My company provides the laptops and will NOT allow you to get their software to use on your own laptop as a mechanic.
+Adept Ape hha damn. I figured that was the case. Thanks man.
Sir problem starting Caterpillar 320
We are having a hard starting with our CAt 315C L excavator. The injector pump is not sending the fuel to the nuzzles. Need advice
I found your channel and subscribed. my 6nz has hat a check engine problem since I bought it. after watching this video it makes me think my ecm could have a problem. I believe it was a code 42 ( it's been a while since I used the cruise control to flash the code). I changed the crank sensor and cam sensor and the wiring looks good. the ecm won't store the code but it comes on and stays on after a little driving, then resets after the key is off a while. any thoughts?
+DANIEL BAIRD Is that code for cam position calibration? If it is you most likely have to check the cam idler backlash, it should be about .014+/- .010. Every time I've seen it, that has been the cause.
thank you for the reply. I have paperwork for a long block that was installed before I bought it, I guess they didn't set it correctly?
That is a very common code on rebuilds. The longblock might not have had a Camshaft and when it was installed it wasn't timed or the backlash wasn't set correctly.
Josh... I have had you help me before. I have a c7 and it randomly dies. It is in a school bus. I have sent it to Holt cat in Dallas. They couldn't get it to repeat the problem 😑 . I Then decided to drive it around for several hours and nothing happened . Drove it back to the day care. 2 day later it was doing the same thing. Even with the driver in the seat going down the road it would die and she could restart it rolling down the road. Then maybe do it again or maybe not for 3 days. Checked wiring/ battery connections haven't checked ECM or related conditions . The engine is in a Freightliner school bus. Your thoughts ?
I have a 04 century with a C15 my truck cut off in the middle of the road was working fine then all of the sudden my speedometer, rpm, oil and temp went out the truck was still on for a couple of seconds but with no response. I check the ign fuse it’s good then check pin 70, 53 and 52 they have power with 12volts while the truck if off. Pin 65 and 67 have 5 volts. I have no codes that I can pull off. When I turn the key on the gages kick in but then they die. Then all of the sudden my temp gage come on and it cranks and everything goes back to normal but then I drive 5 miles and it does it all over again. Do you think that’s a sign for a bad ECM.
I would install a bypass of power and grounds to the J1 connector. If problem goes away it's in the truck side. If problem remains, in the Cat side.
Nice
hey man i need to ask when replacing an 212-9450: CONTROL GP-ENGINE ELECTRONIC Caterpillar with another it need to be program or not ?
+jaafar Kh Yes, all Cat ECMs are unprogrammed and need to be programmed, but it can be done after or before installation.
ok thank you
This was a great video man I learned a whole lot I really want to thank you the dealer was going to beat me across my head $6,000 thank you man
Thanks for the awesome info. I have a 2003 Thomas pusher with a 3126. It stalled while driving and found 20 amp fuse blown that feeds the ECM. When changing and connecting batteries fuse blows. I disconnect the wire harnesses going to ECM and fuse doesnt blow. Am I safe in assuming that the ECM is bad?
I have the. Same issue
@@ttauriinvestments5756 My problem ended up being a bad ECM. I ordered a Remanufactured one from Peterbuilt and had them program it for me. The location in Flagstaff didnt seem to have the knowledge or time to do the work properly, so I would not recommend. I did find GoECM, after the fact, that was a 1/4 of the price.
Having issues with the ECM in a CAT XQ60. Had the generator running, then I shut it down to top off the fuel. When trying to start up again the motor try’s to turn over then it throws a ECM code.
What is a problem of cat 320 over heat,
I prefer mechanical motors, like a 3406b
Which of pin is the nozzle disable in 70pin ecm for c18 cat
Hi..you're right my my oil level is increased..but can this cause a smoke
If your oil level is getting higher you probably have fuel dilution. Which is usually caused by injectors. It is possible that the oil has been thinned out by the fuel and some is getting burned in the combustion cycle. Check out my fuel dilution video to see more about it.
Have you ever worked on Perkins engine 5.9 it in Caterpillar IT28G forklift. It throwing a code PID:1648 FMI:2 . IT crank no start. Any help would help
great video like always got a question buddy My ecm gave me all the injector codes wich it was a bad ecm so I bought one from a guy that rebuilds them 45 days later same thing happened to the new ecm replaced it from same guy cause warranty no problems yet so my question is.? is there something that could cause the ecm to do that or was just my luck with the first ecm thank you in advance c15 acert 2004 475-550 hp
+Luis Gonzalez Cat ECMs are usually pretty good about outside sources affecting them, but have you had any battery issues or other voltages problems? It is possible that something is sending voltage spikes to the ECM and causing a problem, but usually when you get the injector codes fault it's usually a bad ECM internally and not an outside source causing it. I have seen other modules like the ABS module and etc.... cause the ECM to not communicate though because the other model is corrupting the data link, but haven't seen it cause the injector codes. Hope that helps.
+Adept Ape ok thanks Im thinking it was just a bad ecm you have a great channel keep up the good work bud
Hello Guy, I have been troubling shooting 3512B cat engine, cylinder 5 and 8 is not firing have even interchanged injector, check valve, pressurized cylinder, I decided to check cylinder input since the ECM communicate with solenoid in pwm , I have on nos 5&8 is... 1.340hz while the least on firing cylinders are 98.5hz and highest is 245.4hz while engine running at 600rpm idle
thanks
Any experience with cat 3176 mine leaks fuel out top! Can I bypass the ecm by connecting the fuel lines together?
Please please advise
+Josh Cage The fuel is supposed to help cool the ECM, but if your ECM is leaking you can try to loop the hoses and see how long it lasts. It might last awhile or not, but it would be an ECM either way.
Adept Ape hook hoses together with union or wrap fuel line around ecm to help cool?
+Josh Cage I would just connect them with a union, I don't think wrapping the lines around it would give it much cooling benefit.
Adept Ape we connected lines together with a jic 6 union and leak stopped. Truck has ran 600 miles or 24 hrs continuously no issue yet but it in January in Indiana and the high outside temperature is 15 today.
I have a generator problem with engine C15 speed hunting.... an indication of oil pressure and coolant temperature error... is that indication the cause of engine speed hunting..? thank you
Not getting any power to injectors. I have tested positive and negative on the right side of the ECM, all tested fine. How do I test other side of the ECM? Please tell me how to donate to your fund, I would be grateful to do if you can help me.
Check the oil pressure sensor at the front of the front of the head. Until it sees sufficient pressure it won't actuate the coils I believe from memory
If I have ECM in a machine . How can I copy the files from it in case to use them in a new one in the future? Thanks in advance
Hi Guy .Ive a 2002 3126 .When my ecm went it acted just like it was a fuel problem for the first day then it began to run rough,then it ran but really really rough.I have 2 of the same year 3126s so i took the other ecm off and put it on and it runs fine.Think i just lucked out.Wonder if other cat motors being same year ect could swap ecm.
A lot of failures is the injector driver fails causing a misfire. Most of which all six can fail and you will have a no start.
A ECM is blank (correct part number required) and first you flash it to the software. Once flashed you can put it in test mode (70 pin ECM's) and for 24 hours the ECM can be changed. After 24 hours of key on time the ECM locks in. Or you can bypass the test mode and program engine serial number directly in. Some engines require injector trim file (ACERT) or four digit code. Your engine may or may not have this. Then you have the FTS/FLS for each engine. That is how much fuel is putting on the piston. So with a used ECM you don't know what HP you have unless you hook up to ET. Then the fuel numbers and the injector codes could be off some. After all of that you have the programming of the truck, PPM for the speedo, any PTO functions if used, automatic or manual trans., engine fan and the list goes on. I always tell people get a jump drive and get a ECM replacement file out of your ECM before it fails and you have a copy of the programming. If you go to Cat they will be charged a used ECM replacement fee from the factory, plus any other labor.
If you do go and have work done on the engine for example and it has the wrong serial number of the engine in it. You could be asking for trouble, as wrong parts could be installed.
How can i get this pin discription in sheet
right now I'm working on a C7 acert. truck will run fine with no codes then suddenly die throwing all 6 injector curcuit fault codes and truck will not restart. I've done the solenoid test then they read short on all of them, I wiggle wiring to no change, unplug connection to valve cover and all read open, only randomly they will read OK after the test has been going on for about 5 mins. ECM?
Most likely an ECM when you get multiple injector current faults.
