TRAC does not Operate [02/2019 - 12/2021]: Description

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

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.

When a communication malfunction with the hybrid vehicle control ECU assembly is detected, TRC (TRAC) and VSC are disabled. Also when the system is malfunctioning, TRC (TRAC) and VSC are disabled and the indicator lights of related systems illuminate.
