Unwanted Activation With RPO JL4











Circuit Description
When the Vehicle Stability Enhancement System (VSES) 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. The VSES activations mostly occur in the turns or bumpy roads without much use of the accelerator pedal. Activations may also occur during aggressive driving. Unwanted VSES 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 EBCM installed
^ The wrong steering gear rack installed
