VSC does not Operate or VSC does not Operate Correctly [12/2019 - 11/2023]: Description

WARNING: This page is about a different variant/trim than selected.

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 hybrid vehicle 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.
