| Callout | Component Name |
|---|---|
| B80 | B80 Park Brake Switch |
| B20 | B20 Brake Fluid Level Switch |
| K9 | K9 Body Control Module |
| K17 | K17 Electronic Brake Control Module |
| P16 | P16 Instrument Cluster |
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.
- When the Electronic Brake Control Module (EBCM) detects low brake fluid level it sets DTC C0267 and sends a serial data message to the instrument cluster, which will illuminate the red brake indicator.
- 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.
