id041500108800


Purpose/Function

•  The brake system warning light turns on to alert the driver if the brake system has a malfunction when the parking brake is released.
•  The ABS warning light turns on to alert the driver if the ABS has a malfunction.

Construction

•  The brake system warning light and ABS warning light are built into the instrument cluster.

Operation

Note
•  If the DSC system and CAN lines are normal, the brake system warning light and ABS warning light turn on when the ignition is switched ON, and turns off after approx. 3 s to check for bulb burn-out. At this time, the brake system warning light remains turned on while the parking brake is applied. However, the light turns off when the parking brake is released.
•  The DSC HU/CM disables the following controls if there is a system malfunction and the brake system warning light and ABS warning light turn on.
ABS warning light turned on:
―  ABS control disabled
ABS warning light and brake system warning light turned on:
―  ABS control and EBD control disabled
•  A warning message is indicated on the center display when the ABS warning light is turned on. For the message content and verification method, refer to the CENTER DISPLAY. (See CENTER DISPLAY [WITH CENTER DISPLAY].)
Brake system warning light
•  The instrument cluster receives (1) a system malfunction indication request signal from the DSC HU/CM via CAN communication.
•  The instrument cluster turns the transistor on (2) based on the system malfunction indication request signal.
•  When the transistor turns on, the brake system warning light turns on (3).
