VSC does not Operate or VSC does not Operate Correctly [12/2017 - 09/2018]: Description

When ABS, 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, TRAC and VSC are disabled. Also, TRAC and VSC are disabled when a DTC is stored.
