ABS Indicator
WARNING: This page is about a different car, the 2003 GMC Safari and 2003 Chevrolet Astro. 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 an ABS-disabling malfunction. The IPC receives a class 2 message from the EBCM requesting illumination.
- The IPC performs the bulb check.
- The IPC detects a loss of class 2 communications with the EBCM.
