Refer to Vehicle Dynamic Systems for schematic and connector information.

Normal Operation
The wheel speed sensor and sensor ring generates a square wave current signal to the ABS module that is proportional to the wheel speed. The ABS module compares the wheel speed inputs from all the wheel speed sensors to determine an impending wheel lockup. Incorrect tire size can set these DTCs as well.





This pinpoint test is intended to diagnose the following:
^ ABS module
^ Wheel speed sensor ring
^ Wheel speed sensor
