Anti-Lock (Yellow)

The ANTI-LOCK indicator has 3 different methods of illumination:
^ The indicator is illuminated whenever the PC detects a loss of communication with the electronic brake and traction control module (EBTCM) and the state of CKT 852 (WHT) is high (EBTCM disconnected).
^ The indicator is illuminated by the PC whenever the EBTCM sends a class 2 message requesting illumination, via the class 2 serial data line.
^ The indicator is illuminated by the IPC during bulb check.
