Question about 2002 Oldsmobile Silhouette

1 Answer

I had the ABS light come on along with the service traction control. I had it checked at a GM dealer and was told that the right hub needed to be replaced. I OK'd the work thinking it would take care of both of the service lights. The ABS light is out but the traction control light still comes on when making turns or when backing up at times. The GM service rep said nothing could be done until the light stayed on. What is causing the light to come on when traction control is not even needed?

    I mentioned the possible solutions you posted but was told no scan fault came on with these results. What is my next step? There is now a noise as if the traction is working then it turns off traction and it can not be flipped back on. Turning off the car and restarting will at times have the light go off. The problem is that when they check it no fault is coming up. This is what is confusing me.

    Have an appointment with different dealer next week. I will ask them to check what you recommended.

Hi,the traction control light coming up means there is a fault detected in the system and a scan tool will be required to learn what fault has been detected. Possible steering angle sensor, wheel speed sensor or brake pressure sensor since the light comes up when making turns or when backing up. Faults are to be checked and proper diagnostic procedures carried out before parts replacement remedies.....

Most common issue is wheel speed sensor bad or reading poorly because wheel bearing is worn. GOOD scan tool will read ABS codes and tell you which wheel.

It's usually the sensor inside the wheel hub or the wiring harness to the brake controller. The service traction light will set a trouble code. If your mechanic is stumped, authorize him to call a GM tech support line. The call is $50, but the GM tech support can help him figure out what's wrong.

2002 Buick Rendezvous Service traction system and ABS lights, grinding when turning ans braking


The ABS and Service Traction system may be due to bad sensors or signal reaching the ABS/Traction Control computer. The grinding may be due to uneven or unsmooth rotors, and/or worn out pads or shoes.

I would recommend that the entire braking system be diagnosed at your local dealer or brake service facility.

Have a 2004 Chevy Impala recently purchased used.


sounds like you have a wheel hub out causing the lights to come on. odds are it would be the front left. it's not sensing right causing the traction control to be turned on. or it could be a loose wire for that hub. gm cars has had a problem with these two issues.

Impala - trac off and ABS light along with service traction syst


THE PROBLEM IS WITH A HUB WHEEL SPEED SENSOR OR MORE LIKELY THE HARNESS LEADING TO THE HUB.

CHECK THE RESISTANCE AT THE HUB CONNECTION, IT SHOULD BE BETWEEN 900OHMS AND 1300OHMS. THEN SWITCH TO A-C VOLTAGE, IT SHOULD BE 100MV WHEN TURNING THE WHEEL BY HAND. IF BOTH CHECK OUT THE PROBLEM IS IN THE WIRING TO THE HUB.

THE RIGHT FRONT HUB USUALLY HAS A BEND, DOWNWARD THEN UPWARD NEAR THE CONNECTOR TO THE HUB. THAT IS WHERE THE PROBLEM USUALLY OCCURS.

NEW HARNESS WIRES CAN BE BOUGHT AT THE DEALER.
