Electrical Specification
NOTE:
- Terminal numbers in VSC (VDC) CONTROL MODULE & H/U connector (on the control module side) are shown in the figure.
- When the connector is removed from the VSC (VDC) CONTROL MODULE & H/U, the brake warning light (EBD warning light), ABS warning light, VSC (VDC) warning light & VSC (VDC) operation indicator light and VSC (VDC) OFF indicator light illuminate.
