Purpose/Function
The brake system/ABS warning light is built into the instrument cluster. If a malfunction is detected in the system with the parking brake released, the warning light illuminates to notify the driver.

Construction/Operation
When the DSC system and CAN lines are functioning normally, the brake system/ABS warning light illuminates when the ignition is switched to ON to check for a burned-out bulb, and then turns off after approx. 3 s. At this time, while the parking brake is activated, the brake system warning light remains illuminated, however, it turns off after the parking brake is released.
The brake system/ABS warning light illuminates during a system malfunction, and the control is as follows:
ABS control disabled.
ABS and EBD controls disabled.
