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 detects a loss of class 2 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 3 seconds.

When the ABS indicator is commanded on the IPC also illuminates the TRACTION CONTROL indicator and illuminates the SERVICE STABILITY SYS indicator in the DIC.
