Four Wheel Antilock Brake System

NOTE: Chrysler only provides a procedure to pull ABS Codes with a Chrysler Diagnostic Readout Box (DRB) scan tool. There are no procedures provided by Chrysler to pull ABS codes with a generic scan tool or any other procedure besides using the Chrysler DRB.

The ABS brake system performs several self-tests every time the ignition switch is turned on and the vehicle is driven. The CAB 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.
