Pinpoint Test J: Vehicle Pulls During Braking or ABS False Activation/too Sensitive/Activates On a Normal StopNormal Operation
The wheel speed sensors are "active" sensors and generate a square wave signal that is sent to the ABS module. When the ignition is turned to the RUN position, the ABS module carries out a self-test to determine if the sensors are functional. Voltage and ground are supplied to the front wheel speed sensors from the ABS module along a pair of wires.
Wheel speed sensor DTCs will automatically clear when a successful test drive is carried out. A successful test drive should include speeds above 32 km/h (20 mph) and at least one ABS stop.
This pinpoint test is intended to diagnose the following:
^ Mismatched tire sizes
^ Wheel speed sensor ring
^ Wheel speed sensor
^ ABS module
