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 sends a class 2 message to the Body Control Module (BCM) indicating that the ABS indicator is illuminated. The BCM sends a class 2 message to the radio in order to activate an audible warning.
^ 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.
