VSC OFF Indicator Light Circuit: Description
The skid control ECU detects malfunctions in the VSC system. When the VSC system's operation is stopped by the skid control ECU, the ECU informs the driver by blinking the VSC OFF indicator light. When the VSC OFF switch is pressed for a short time, TRAC operation is prohibited, and the combination meter's slip indicator light illuminates. When the vehicle is stopped and the VSC OFF switch is pressed for 3 seconds or more, VSC and TRAC system operations are prohibited, and the combination meter's VSC OFF light illuminates. With the system in TRAC OFF mode through the VSC OFF switch, if the vehicle speed becomes high, TRAC operation is automatically changed to an operational state. If the system is in VSC OFF mode, VSC operation is not affected by vehicle speed.
