ABS Indicator
WARNING: This page is about a different car, the 2010 GMC Sierra and 2010 Chevrolet Silverado. 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 electronic brake control module (EBCM) detects an ABS-disabling malfunction and sends a serial data message to the instrument panel cluster requesting illumination.
- The instrument panel cluster performs the bulb check.
- The instrument panel cluster detects a loss of serial data communication with the EBCM.
- A DTC is set during the previous ignition cycle which requires an United Nations Economic Commission for Europe regulation number 13 (ECE 13) response at the beginning of the current ignition cycle. The EBCM sends a serial data message to the instrument panel cluster requesting illumination.
