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 IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
^ The IPC detects a loss of class 2 communications with the EBCM.
