WARNING: This page is about a different car, the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, and 2002 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
The ABS indicator illuminates when one or more of the following occurs:
- The electronic brake control module (EBCM) detects an ABS disabling malfunction.
- The EBCM performs the bulb check.
- The pressure differential switch is off-center due to a base brake failure (export only).
- The ground circuit between the electronic brake control lamp relay and the EBCM is open (export only).
- The EBCM does not power up or loses power during the ignition cycle.
