VSC Warning Light Does Not Come ON

BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM (for BOSCH Made): VSC Warning Light does not Come ON

VSC Warning Light does not Come ON

DESCRIPTION

The skid control ECU communicates with the combination meter assembly via CAN communication. If the ECU stores a DTC, the master caution indicator light will illuminate, and the DTC will be displayed on the multi-information display in the combination meter (models with multi-information display). On models without a multi-information display, the VSC warning light will come on when the skid control ECU stores a DTC.
