Anti Lock Brake Indicator

The ANTI-LOCK indicator is controlled by the Electronic Brake Control Module/Electronic Brake Traction Control Module (EBCM/EBTCM) over the class II serial data line. The EBCM/EBTCM will turn the indicator on for approximately 3 seconds during engine start-up for a bulb check. The EBCM/EBTCM will flash the ANTI-LOCK indicator to warn the driver that an Antilock Brake System (ABS) malfunction exists which may have degraded base brake performance. A solid (not flashing) ANTI-LOCK indicator warns the driver that a problem has been detected that affects the operation of the ABS (ABS may be disabled), but normal brake performance will remain. For more information on ABS, refer to Antilock Brake System. Antilock Brakes / Traction Control Systems
