4. Wheel Direction Sensor

The wheel direction sensor (S65) detects travel direction information from the top of the drive unit. This sensor works in conjunction with the steer angle proximity sensors (S66) and (S67) located in front of the drive unit and accessed from the battery compartment.

4.1. Adjustment

CAUTION Adjustment of sensor with wheel nuts facing inward will result in shearing of sensor when the drive wheel is rotated.

1.Position drive wheel with wheel nuts facing outward. 2.Turn key switch OFF and disconnect battery at battery connector. 3.Remove dash, motor compartment door, and left hand panel to allow access to drive unit. 4.Loosen jam nut securing the sensor to the frame. 5.Turn wheel direction sensor by hand in a clockwise direction until it contacts the drive unit housing. 6.Back sensor out by turning the sensor counterclockwise 1-1/4 turns. 7.Tighten jam nut securing the sensor to the frame. 8.Connect battery connector to the truck. 9.Test operation of the sensor.
