• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

What did you do to your Car today?

It goes from the PCM straight to the PCM, Should be Pin 14 on C1 of the PCM and Pin B on the EBTCM connector. The other numbers on the line are wire colors, connectors in between, and wire colors after.

It's under Diagrams, Electrical Diagrams, Antilock Brakes / Traction Control Systems.
 
i just dont want to start poking wires now.

so i can just see if any power is sent back on the return wire to the pcm?

ive had like 4 pcm's in this car so far, they all do this. so its not the pcm. thats for sure.
 
I don't know much about tuning, so this might be a shot in the dark, but it happened on the stock tune?

Other 3 are uploading, 1 is just the wheel sensors though...

After I get these posted I'll start digging around on the code itself and see what Alldata says.
 
oh, yeah this is a 5 year abs issue, stock, stock pcm, new pcm's new battery, old worn battery, same deal.

and ive done wheel bearings cause when they were bad i got the light a lot more often, but that tripped when driving. loose hubs were replaced. random driving abs lights is super rare now.

it will light up the light after i start to drive from a start up and fail the abs test. you hear the crunch sound of the abs test then the light flips on.
 


looking closer at the first one, that pcm signal looks to go to the ebcm inside the car, its showing 3 plugs in and i got that on mine.

its a start, thanks.
 
Ya know, Alldata is saying C1276 is Brake solenoid problem...
EBCM is in the car for you guys? It's on the ABS unit for us. Make sure you aren't confusing BCM with EBCM, just saying, lol.
 


Cleaned the MAF in preparation for the in car tune being done Saturday. Also washed it and treated the leather with some conditioner.
