ABS Indicator

The Electronic Brake Control Module/Electronic Brake Traction Control Module(EBCM/EBTCM) over the class II serial data line controls the ANTI-LOCK warning indicator. The EBCM/EBTCM turns the indicator ON for approximately 3 seconds during the engine start up in order to perform a bulb check. The EBCM/EBTCM flashes the ANTI-LOCK warning indicator in order to warn the driver that an ABS malfunction exists, possibly degrading the base brake performance. A solid (not flashing) ANTI-LOCK warning 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. Refer to Antilock Brake System.
