Unwanted Activation - No DTC Set

Part 1 Of 2:




Part 2 Of 2:











CIRCUIT DESCRIPTION
When Stabilitrak or TCS activates for longer than 1.5 seconds, there will be an accompanying DIC message. Short activations of either system may occur without any DIC messages. Stabilitrak activations mostly occur in the turns or bumpy roads without much use of the accelerator pedal. Activations may also occur during aggressive driving. Unwanted Stabilitrak activations may be caused by the following:
^ A loosely mounted yaw rate sensor
^ An intermittent faulty steering wheel position sensor
^ An intermittent wiring harness problem
^ A chassis alignment that is grossly out of specification
^ The wrong EBTCM installed
^ The wrong steering gear rack installed
