BRAKE Indicator (Red)

The BRAKE indicator may only be ON during RUN. The IPC illuminates the BRAKE indicator under the following conditions:

    • During the bulb check.
    • The park brake is ON.
    • The brake fluid is low. The IPC also displays the CHECK BRAKE FLUID message on the DIC and sends a class 2 serial data message requesting a single chime to sound.
    • The electronic brake control module (EBCM) sends a class 2 serial data message requesting illumination due to a concern in the ABS system.
    • The IPC detects a loss of communications with the EBCM.
