ABS

The ABS indicator may only be ON during RUN. The IPC illuminates the ABS indicator under the following conditions:
^ During the bulb check.
^ The Electronic Brake Control Module (EBCM) sends a class 2 serial data message requesting illumination due to a concern in the ABS system.
^ The IPC detects a loss of communications with the EBCM and the back-up discrete ABS indicator signal is open.

When the ABS indicator is ON, the IPC also illuminates the TRACTION CONTROL indicator and displays the SERVICE STABILITY SYS message on the DIC.
