The instrument cluster turns the brake warning indicator ON when the following occurs:
• | The instrument cluster performs the bulb check. The brake warning indicator illuminates for 5 s. |
• | The electronic brake control module (EBCM) detects a faulty pump motor, solenoid valves, an internal hardware failure or a too high or too low battery voltage and sends a serial data message to the instrument cluster requesting illumination. |
• | The body control module (BCM) detects that the parking brake is engaged. The instrument cluster receives a serial data message from the BCM requesting illumination. |
When the EBCM detects a too low brake fluid level it sets DTC C0267 and sends a serial data message to the instrument cluster, which will display the following message:
BRAKE FLUID LOW
