ANTILOCK BRAKING SYSTEM
The ABS brake system performs several self-tests every time the ignition switch is turned on and the vehicle is driven. The ABM monitors the systems input and output circuits to verify the system is operating correctly. If the on board diagnostic system senses that a circuit is malfunctioning the system will set a trouble code in its memory.
NOTE: An audible noise may be heard during the self-test. This noise should be considered normal.
NOTE: The scan tool is used to diagnose the ABS system. For additional information refer to the Electrical, Electronic Control Modules section.
