VSC does not Operate or VSC does not Operate Correctly [11/2018 - ]: Description

When TRC (TRAC) or VSC is operating, the skid control ECU (brake actuator assembly) blinks the slip indicator light to inform the driver that slippage occurred.

When a communication malfunction with the ECM is detected, TRC (TRAC) and VSC are disabled. Also, TRC (TRAC) and VSC are disabled when a DTC is stored.

When in VSC off mode, or TRC (TRAC) and VSC are disabled, the multi-information display in the combination meter assembly displays "TRC (TRAC) OFF message" and the VSC OFF indicator light illuminates to inform the driver.
