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.
When the DSC system and CAN lines are functioning normally, the brake system/ABS warning light illuminates when the ignition is switched 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 warning light illuminated:
ABS control disabled.
ABS warning light and brake system warning light illuminated:
ABS and EBD controls disabled.
Function not equipped.
