How to Calibrate a Replacement
Steer Sensor
Note: If a steer angle sensor has been removed or
replaced, the steer angle sensors will need to be
calibrated first.
Note: Perform this procedure with the axles
retracted and the tires straightened.
Note: Two people will be required to perform this
procedure.
Note: Be sure the yoke pivot pin retaining plate is
fully engaged into the pivot pin and that the
fasteners are securely tightened.
1 Start the engine from the platform controls.
2 Select the proper steer mode. If a front
(square-end) steer angle sensor has been
replaced, select rear steer mode. If a rear
(circle-end) steer angle sensor has been
replaced, select front steer mode.
3 Have another person press down the foot
switch.
4 At the new steer angle sensor, loosen the
steer angle sensor cover retaining fasteners.
Do not remove the fasteners or the sensor
cover.

counterclockwise until the tire is straight in
relation with the other tires. Tighten the
sensor cover fasteners.

this procedure.
