Is my PCM going brain dead?
Is my PCM going brain dead?
I havn't been driving my 97 Camaro in about a year and a half due to a problem I couldn't diagnose. I would be driving and the car would just die, and it would take a little bit to start back up. The car would then Start to cut off at about 3000 RPM. Well, I put the car in the garage ( don't have much money to spend trying to fix it) and I pulled it out about a month ago and the car was running fine now. BUT, the traction control is constantly off and the ABS inop light is on. I went to a friend that does mechanic work on the side and pulled the ABS log with a snap-on scan tool and every code was thrown- I believe more than 50 codes came up. So, I have no idea what is going on with it. If any one can chime in with some info, it would be greatly appreciated! Thank you! Tyler
Sounds like you may have a ground problem for the EBCM control or the ABS motor assembly. Might also be affecting the engine, causing it to cut out. Did you ever scan the PCM to try and determine why the engine was running poorly before you put it in storage?
Yeah, I had scanned it and it came up with a code for the crankshaft position sensor. I replaced it, but by that time the car was running fine, just the ABS and trac control was messed up.
