Wheel Speed Sensor (WSS) Screen
The Wheel Speed Sensor screen allows the technician to record the sensor output as the wheels rotate.
Additionally, there is a sensor air gap field which indicates the wheel speed when the sensor starts
registering speed. A lower air gap speed value (e.g. 3 to 4) indicates a properly adjusted wheel speed
sensor. An air gap speed value higher than 5 typically indicates that the wheel speed sensor needs to be
adjusted by installing the sensor so that it is close to the tone ring — eliminating the distance between the
sensor and tone ring (See the Service Data sheet for wheel speed sensors for more information).
