Brake System Indicators
BRAKE
The 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. 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 DIC and sends a
serial data message in order to activate an audible warning when the
IPC detects a that the brake fluid level is below the normal operating range.
