ABS Indicator
WARNING: This page is about a different car, the 2012 GMC Yukon XL and 2012 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster illuminates the ABS indicator when the following occurs:
- The EBCM detects a malfunction with the antilock brake system. The instrument cluster receives a serial data message from the BCM requesting the ABS lamp illumination.
- The instrument cluster performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 5 seconds.
- The instrument cluster detects a loss of serial data communications with the EBCM.
