Indicator Lights: Anti-Lock

LED is controlled by IPC, using information sent by Electronic Brake Control Module (EBCM) on Class 2 serial data line. If light is on, brake system will still operate, but without anti-lock assistance. As a check, LED illuminates for 3 seconds after ignition is turned on. LED illuminates when one or more of the following conditions exists:

Anti-lock brake system related DTC is set.
Instrument cluster cannot communicate with EBCM on Class 2 serial data line.
Instrument cluster receives a Class 2 serial data message from EBCM requesting ANTI-LOCK indicator on.

WARNING: If BRAKE light is on, ensure brake hydraulic system is okay before driving vehicle.
