SOURCE: 2001 oldsmobile silhouette traction corntol is off and ABS light

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

SOURCE: abs light/traction control light

You can check out what the trouble code is by pushing and holding the information button and the up arrow (right side of instrument cluster above the radio) until all the instrument clusters light. Press the information button (last) to enter test mode. I've had an error C1234, meaning Left rear wheel sensor fault. I found the problem to be a corroded connector under the chasis just under the rear left door about 2 feet in. I had to by-pass (replace 1 wire due to corrosion at the connector.

SOURCE: 2003 Cadillac CTS - the car won't shift from park

sounds like you have a bad brkae light switch, which is located on the brake pedal assembly. a bad switch will not let you shift out of park and you will not have any brake lights as the car does not recognize that the pedal is being pushed and brakes engaged. easy to replace switch if you are handy, if not this is a inexpensive repair at any mechanic. hope this was helpful is so please rate 4 thumbs.

Low brake fluid level could cause that. Bad ABS wheel sensor. Brake switch. Go to Autozone and ask them to put the scanner on and see what codes you're getting.

well while putting the car on the lift, traction control does not need to be disabled, and will not cause the abs/traction light to illuminate, these cars are known to have terrible wheel speed sensors that are brittle and tend to brake or malfunction for no apperent reason, and the wheel speed sensors are what control your abs and traction conrol units and they are normally what make the light come on on your dash, the warranty on the sensors was prolonged for that reason, so depending on the mileage of your car they might be covered, hope this helps

What if the traction control and anti lock break system light is on


You most likely have a problem with one of the wheel speed sensors, the related wiring, or the ABS system itself. The traction control and ABS system both work together and rely on the same input information to work. A fault in the ABS system will cause both the ABS and TRAC control lights to illuminate and both systems will be disabled until the fault is gone. I would have a good service facility or dealer look at this one. One quick check you can do is to make certain that the brake fluid master cylinder is properly filled with brake fluid because if it is low enough it can also cause the systems to be disabled.
