What is this code?

wiring...wiring...wiring... do a search on j1939 datalink issues here. A faulty module on the backbone is always the least probable cause.

 

That's exactly what I was told at the shop. Then I got a call saying they were going to bring in a test ECM. Then they said my old ECM was definitely dead and I needed a new one.

They did an extensive test of the wiring and found that my mechanic had ####ed it up in several places. Their conclusion was get an ECM and that will fix it.

Fingers crossed but I'm still skeptical. I'm also wondering if my oil change brake change guy purposely ####ed my truck up so he'd have a parts truck.

The new shop kind of hinted at that. They said there were some substantial cuts in the wiring harness.

Please be careful who you entrust your truck to. I'm on my 3rd week down and am looking at $4000 out of pocket. Wish me luck.

 

So am I seeing this wrong but you're throwing a high $$$$ module at the problem because the wiring was damaged???????

I fail to follow the logic here. If you know the wiring is no good, fix it first and go on from there.

 

The wiring was fixed but the module would not read. A test module was put in and it read. Mechanic said old module was no good.

Im just following the advice of my mechanic.

 

Ok I didn't see you post anything indicating the wiring was repaired.

 

Yeah, they told me before I towed it to them that it's rarely the ECM. They stressed that it's almost always the wiring.

Then the wiring specialist went through everything and eliminated wiring problems. A sister shop lent them an ecm that actually read. And that's when they called and gave me the news.

My oil change/ brake mechanic was working on my AC compressor and couldn't get power to it. It seems that in the process of taking the switch out of the dash and messing with the wiring harness, he fried the ECM.

My gut told me not to trust him with the AC. Should've followed my gut.

Wish me luck. 2 weeks at home has me going nuts.

 

New ECM installed and the truck is running again.

Apparently, the AC guy tried to tap into the data link to get power to the AC compressor and it killed my ECM in the process.

Now I've got to deal with an oil leak at the drain plug. I just hope he didn't over torque the plug and crack the pan.

 

Wow. That is a fail right there.

 

See that a lot. I do many network repairs as a network engineer and mechanics tried to tap into places or they added something and a screw went through the wires, causing grounding, then a shock to the ECU that causes it to burn out.

 

And that's what happened. Almost $5000 later and I'm back up and running.

I'm just happy I had the capital to get moving again.

No hard feelings for my oil/ brakes mechanic. #### happens and I am lucky enough to have a box of straws to suck it up and move on.
