I have a 96 cadillac deville and the traction control light stays on.
The traction control light stays on and it feels like i am driving in four wheel drive. Also ive been having problems starting my vehicle sometimes its fine and sometimes i really have to crank it over for a minute i just did a tune up and it didnt help much someone said it could be a check valve in my gas tank is that true?
Re: i have a 96 cadillac deville and the traction control...
The starting problem may be the fuel pressure regulator. Remove the small tube from the back of the fuel pressure regulator with the motor running, and if fuel comes out it's bad. The part is under fifty bucks at autozone. I did mine, and now it starts normally.
As far as the traction control light, it could be anything from a wheel sensor to the EBTCM, or a bad wiring connection anywhere inbetween.

Sounds like a fault with the Antilock Braking System. The vibration in the pedal is the ABS working. With your foot on the brake pedal, it releases and re-applies the brakes to stop a skid from the wheels locking up. You need professional service for brakes.
Seems to be a known issue on all Cadillac and requires the ABS module to be replaced.
The ABS harness from the new wheel bearing is in the correct clock position?
Are you sure one of the pins in the connector isn't bent? Look carefully in the sensor side of the connector. The male pins are very small and easily bend.
Check the harness on the car side of the connector. It is very common for the harness to break or corrode especially near the connector or anywhere along the harness where it routes through the wheel well area.
each wheel has it's own sensor and it's an integral part of the wheel hub. if you have a problem, the computer will tell you which wheel is the problem and you will have to change that hub. not a hard fix, but the fronts take more time bcuz of the drive axle.
Try seeing if any of the codes are set off. On your climate control section with the ignition on hold the off and warmer button and the display will cycle through the codes. Could be a wheel sensor I had a c1225 LF sensor. Could also be a problem with the Wheel speed sensor harness see TSB# 0005-25-003. When I called my dealer about this TSB they didn't know anything about it. If you shut off the car and disengage the traction control, in the glove box, do the codes go away?
Traction Control system adjusts your throttle and braking automatically to help keep your car from slipping on wet/snowy roads. If the light flashes momentarily then that means it is doing the job properly. If the light flashes constantly or stays on then it indicates a problem with the traction control or ABS system and could pose a safety concern.
