I got a 2001 bonneville and the traction control doesnt stay on i just changed the switch on the counsel. When ya first start it it may stay on for a cpl min then it goes off checked the brake fluid but it is full the anti lock brakes work so i assume the sensors are ok dont know what else could be wrong any suggestions?

Very possilby a wheel speed sensor (one at each wheel) has gone bad or has lost connection. This is the most common item. You could pull all the wheels and check each connection however the only way to truly tell is to have a dealer scan the car.

Billboost is right, but you can just turn wheel to left and right and take a look at the connections of the wheel speed sensor.

That the only connector you will see attach to the wheel.
If those connector are still connected, thats may be a Wheel speed sensor.Wich require buying a new wheel bearing, the wheel speed sensor come with the bearing

Does your ABS or parking brake light come "on"?

Good luck

no my abs or parking light does not come on sometime the traction control will work for awhile like maybe 45 min or so others as soon as ya start the car it goes off

Try pulling the C2 connector at the Electronic Brake Control Module (EBCM), examine it closely, then reconnect.

where would that be and what am i looking for?

Which indicator light are you going by to say the TC is not on?
Are you reffering to the led in the TC switch itself or are there any other indicators on the dic (ie service stability system)?
First you should have the car scanned for any dtc'* if there were a problem with the EBCM then a code would have been set.
The book reads the only 3 things can turn off the tc light
dtc set by the ebcm
driver turned off the switch
bulb burnt out

btw: The EBCM is located under the hood on the drivers side, in front of the radiator on the lower cross member. It is a large aluminum block with brake lines and a connector to it. Make sure the ignition is off before removing this connector.

the light on the dash that says trac. off when it goes off it dings then the light on the switch goes out also
