Question about 2001 Oldsmobile Silhouette
2001 oldsmobile silhouette traction control light says it is off. Service traction control system display message will display for 10 seconds. The abs light is on. I have checked the brake fluid level. Checked shoes and pads and fuses. Everything I looked at seems ok. When I start the van with my foot on the brake I get no messages and no idiot lights. As soon as I release the brake pedal then the messages appear. The messages also appear if I start the van and my foot is not on the brake pedal. Can you help?
I agree with the post about the tail lights. And the symptom about the brakes on when starting was also helpful. When I took off my rear tail lights and removed the top light bulb (top of the 4 is closest to connector) then repeat starting the car the problem is gone. I have a whole drawer of these bulbs that I removed, not because the filament was burned out, but because the base (similar to circuit card edge connector) had heat damage and melted. I am not sure exactly what the problem is but I think there are multiple conductors in the fixture which are too close or get moisture shorts. Anyway I hypothesize the circuit for daytime running lights is leaking current into the brake light circuit, and it causes that module that controls traction control and ABS to declare a fault. When you start with foot on the brakes the brake lamp is pulled on (I don't know if switches hi or lo) so that module doesn't declare the fault until you release the brakes.
I put in new bulbs and it works fine for now, but I know it may reappear some day then I will repeat, disassembly of the fixtures and inspect bulb bases for heat damage and clean out and replace. That is what did the trick for me.
Thanks Fixya and all contributors
