So now I have replaced the ebcm, the rear abs sensor, and just checked the wiring. Everything is good, yet somehow the problem persists. Question, does the ebcm have any communication with my computer under the hood where it could have something faulty? It seems like everything is good yet there is something wrong...
thanks

Maybe it's a different code this time!? Have you had it scanned lately since you did all that? although, a soft code that clears up and comes back when you start to drive is almost always the sensor circuit. You didn't buy an EBCM without testing someone elses first did you? If it's the same problem, I would put money on it being wiring before I would think the PCM is defective.

Well I went over to a guy from the boards house to use his computer, and after working for a long time in the sweltering heat, i got his computer out to realize he had traction control and I didn't. But I bought one on ebay that was only $20 and the guy said it worked. It seemed to work because I had no troubles until i started driving, like normally. So now I have an extra, I like to have spare parts anyways, and for $20 it didn't really cut into my income. We checked the wiring and nothign was grounded and it was all connected, using a meter to test it, from the sensor end up to the computer end. In my mind, that ruled out being a wiring problem.. but obviously something is awry.

Now it's time to check the wiring from the EBCM to the PCM.

ohhh....I wasn't aware that the two were connected. Well I'll see if I can read up on that and find the wires.
Thanks

This might sound stupid but did you ever check or change your abs relay in the black box under the hood?
