ABS

The IPC illuminates the ABS indicator when the following occurs:
- The Electronic Brake Control Module (EBCM) detects a malfunction with the antilock brake system. The IPC receives a class 2 message from the EBCM requesting illumination.
- The EBCM performs the displays test at the beginning of each ignition cycle. The indicator illuminates for approximately 3 seconds.
- The IPC detects a loss of class 2 communications with the EBCM.
