ABS Indicator

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.
