Brake System Indicator
The IPC illuminates the brake indicator when the following occurs:
| • | The body control module (BCM) detects that the park brake is engaged.
The IPC receives a class 2 message from the BCM 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 IPC performs the displays test at the start of each ignition
cycle. The indicator illuminates for approximately 3 seconds. |
