Brake System Indicator
The instrument panel cluster (IPC) illuminates the brake indicator when the following occurs:
| • | The electronic brake control module (EBCM) detects that the park brake is engaged. The IPC receives a serial data message from the EBCM requesting illumination. If the vehicle is shifted out of park with the park brake engaged, the BCM activates
an audible warning. |
| • | The IPC detects a low brake fluid condition (signal circuit is low). The EBCM receives a serial data message from the IPC requesting illumination. |
| • | The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds. |
