So my 99 gtp has the abs/tcs light currently on. I took the car to class tonight and the automotive instructor attempted to scan it with a GM TECH 2. It had a code that we cleared for the wheel speed sensor. (fixed broken wire) When he tried to run the test on the abs/tcs the scanner would say "Release Brake Pedal" This is all I was able to find out about my car.. He thinks the EBCM is bad. My only concern is that today, I left for work and the abs primed and the ABS light went out. On my way home from work both lights went out and everything was good. After restarting the car the lights are back on. I'd really like some input.. One instructor thinks it may be a brake switch and the other says EBCM. Im very frustrated right now and would really appreciate some help..
