Brake Warning Indicator
The instrument panel cluster (IPC) illuminates the brake warning indicator when one or more of the following occurs.
| • | The body control module (BCM) detects that the park brake is engaged. |
| • | The BCM detects a low brake fluid condition. The IPC receives a serial data message from the BCM requesting illumination. |
| • | The electronic brake control module (EBCM) detects a malfunction and disables the antilock brake system (ABS). The IPC receives a serial data message from the EBCM requesting illumination. |
| • | The IPC performs the bulb check at the start of each ignition cycle. The brake warning indicator illuminates for briefly 3 seconds turning OFF. |
| • | The IPC detects a loss of communications with the EBCM. |
