ABS Indicators
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
The IPC illuminates the ABS indicator when the following occurs:
- The electronic brake control module (EBCM) detects a malfunction with the anti-lock 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 5 seconds.
- The IPC detects a loss of class 2 communications with the EBCM and the discrete back-up ABS indicator signal circuit is high.
When the ABS indicator is commanded on, the IPC also illuminates the TRAC OFF indicator and illuminates the SERVICE STABILITY SYSTEM indicator in the DIC.
