Brake System Indicators
Brake
The instrument panel cluster (IPC) illuminates the BRAKE indicator and sends
a serial data message in order to activate an audible warning when the following occurs:
| • | The IPC detects that the park brake is applied--signal circuit is
low. |
| • | The IPC detects a low brake fluid condition--signal circuit is low. |
| • | The electronic brake control module (EBCM) detects a malfunction with
the antilock brake system (ABS). The IPC receives a serial data message from the EBCM
requesting illumination. |
| • | The IPC detects a loss of communications with the EBCM and the discrete
back-up ABS indicator signal is open. |
| • | The IPC performs the displays test at the start of each ignition cycle.
The indicator illuminates for approximately 5 seconds. |
Check Brake Fluid
The IPC illuminates the CHECK BRAKE FLUID indicator in the driver information
center (DIC) and sends a serial data message in order to activate an audible warning
when the IPC detects that the brake fluid level is below the normal operating
range.
