ABS light on, TRAC off, Stabilitrac
ABS light on, TRAC off, Stabilitrac off – What does it mean?
If you ain one of the GM vehicles listed below and have any of these warnings: ABS lite on, TRAC off, Service Traction Control Organisation lite on, Service Stabilitrak light and/or have the following trouble codes stored; C0035, C0040, C0045, C0050, on you lot should read this service bulletin #PIC5248E from GM.
C0035 Left Forepart Wheel Speed Sensor Circuit
C0040 Right Front Wheel Speed Sensor Circuit
C0045 Left Rear Wheel Speed Sensor Circuit
C0050 Right Rear Wheel Speed Sensor Circuit Plausibility Failure
Other ABS stabilitrac symptoms
In improver to the warning lights, you may also hear a brief and intermittent noise, click, ratchet, grind, or ABS pump motor noises from the inside of the vehicle at parking lot speeds when braking. Or, if your vehicles is equipped with Electrical Power Steering yous may too detect a Service Steering Message displaying in the Driver Data Center (DIC). Yous will most probable experience heavier steering experience at low speed or static steering maneuvers when this happens. This condition is normal when the vehicle loses indicate from a wheel speed sensor.

The cause of these trouble codes and braking noise is droppings accumulation on the magnetic "tone" wheel built into the cycle bearing. You do NOT have to supersede the bike bearing to right this problem. Here'south why:
Older ABS braking systems used a steel toothed ring and a magnetized wheel speed sensor. As rust accumulated on the tone band it would throw debris onto the magnetic sensor and that debris would interfere with the betoken, causing the ABS to activate prematurely.
GM changed the wheel speed sensor and tone rings in these vehicles. At present, instead of a steel tone ring, it is a rubberized band with magnetic North and South poles molded into the nitrile safe (similar a magnetic business card). The bike speed sensor is within the bike bearing and the tone ring is mounted on the outside of the similar a seal in a sealed begetting. Dandy idea but bad execution on GM'south part. GM figured that the emptying of the steel tone ring would stop the aggregating of metallic debris. That's partially truthful. But at that place'south enough metallic droppings on the road that any accumulation on the magnetized rubber ring can throw off the wheel speed sensor.
Fix the wheel bearing
Inspect the wheel bearing associated with the trouble lawmaking. Wait for debris build up on the magnetized ring. Wipe it off with a dry nylon bristle castor. If that doesn't
Make clean the Nitrile rubber ring
remove all the debris, wash the ring with mild lather detergent. Then clear the trouble codes and exam drive.
In some severe cases, you may accept to remove the cycle bearing to remove all the debris.
If the codes are still present and the band is clean, proceed with normal diagnostic procedures.
