WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
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.
