VSC does not Operate or VSC does not Operate Correctly [11/2020 - ]: Description

When ABS, TRAC, VSC or trailer sway control is operating, the No. 2 skid control ECU (brake actuator assembly) blinks the slip indicator light to inform the driver that slippage occurred.

When a communication malfunction with the EV control ECU is detected, TRAC and VSC are disabled. Also, TRAC and VSC are disabled when a DTC is stored.

When in VSC off mode, or TRAC and VSC are disabled, the multi-information display in the combination meter assembly displays "Traction Control Turned Off" and the VSC OFF indicator light illuminates to inform the driver.
