Check Engine/ABS Active handing light
1999 C5 VERT 95000 miles
Check engine light comes on here and there if I clear the PCM codes it turns of then comes back within 50 miles or so, I have done this 4 or 5 times now. The ABS/Active handling light would come on when i started her up but would turn off after about 10 minutes but now are on all the time, for the last month so. The HVAC will not work while the ABS/ Active handling lights are on.
I have started cleaning the ground connector plugs, the easy ones to get to, under the battery and the side ones inside the engine compartment. Do I need to completely disassemble the connectors?
I live in Ca in the Redding, Chico area, anyone know a good mechanic?
I haven't noticed any performance issues with it?
Basically, should I not drive this until I fix it?
Thanks for your time.
Codes are:
PCM 0135 0155 0161 1571 1689 all current
BCM 0432h 2578h 2583c 2723c
TCS No comm

I recommend checking the following based on your DIC codes and "no comms":
* Check, clean and use dielectric grease on ground connections
* Driver door connector (wiggle driver door rubber accordion)
* Ignition switch - possibly loose or dirty connectors
* Check battery condition (amps) & tighten/clean side terminal
Weak battery or poor side terminal connection can cause strange things to happen.
