The instrument panel cluster (IPC) illuminates the Antilock Brake System (ABS) indicator when the following occurs:
- The electronic brake control module (EBCM) detects a malfunction with the antilock brake system. The IPC receives a serial data message from the EBCM requesting illumination.
- The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 5 seconds.
- The IPC detects a loss of serial data communications with the EBCM.
