To make a long story short, a little more than a week ago I installed rear shims on both sides because the toe was off and I aligned it and it straightened out the rear (note: there were shims already installed but were removed and installed with the corrected ones) a week later my ABS, trac off, service wrench and brake light all come on. Its very random timing as well. Usually first the ABS, trac off and brake light will come on, then randomly the ABS and brake light will go out and the service wrench will come on but the trac off just stays on. Then randomly the ABS and brake light will come on. So it basically starts with three lights (ABS, brake, trac off) then randomly switches between two lights(service wrench, trac off) and four lights(ABS, brake, trac off, service wrench). History codes are c1234, c1235, u1000, u1016. Diagnostics has been hard to do because the lights switch randomly so I have not been able to capture current codes but I did do data display with service wrench and trac off lights on and all four sensors were reading and I tested both rear connectors and got 4.74 volts on each side. It seems to be more active when it rains out. My question is could the shims be causing the rear ABS to be wonky or does it sound more like a wiring issue? This car had shims in it before and never had issues. Thanks
have the same problem?
