Wheel Angle Sensor Installation
A Wheel Angle Sensor is required to provide the GeoSteer system with an indicator of what direction the steering axle is
pointing compared to the vehicle position at all times. This allows the system to more accurately determine how far and how
fast it must command the steering axle to reach the required position for smooth steering. It is critical that the Wheel Angle
Sensor be installed correctly with adequate counts to provide a high resolution of the steering axle’s position.
The Wheel Angle Sensor kit comes with rods that need to be cut to the correct length prior to installing them. The vehicle-
specific installation manual provides guidelines for the lengths these rods need to be cut for a typical installation; however
these values are for reference only. There are many different axle configurations and wheel stop settings that an individual
vehicle can be set that cannot be addressed in a manual. Though the manual provides cut lengths and suggested rod assembly
lengths, it is ultimately the installer’s responsibility to verify the suggested measurements will work on their particular
installation. If necessary, the lengths may need to be modified to prevent damage to the vehicle and/or Wheel Angle Sensor.
Note: Prior to turning the wheels manually or with the GeoSteer system, always verify that the Wheel Angle Sensor linkage
rods will not bind, be damaged, or damage the vehicle or Wheel Angle Sensor when the steering axle is turned from the full
left to full right positions. Always disconnect the linkage rods the first time the wheel is turned to the maximum limit.
Reconnect the linkage rods at the maximum limit and then disconnect them while they are moved to the opposite limit.
Refer to the Wheel Angle Sensor (WAS) Installation chapter in the vehicle-specific AutoSteer
Installation Manual provided with the installation kit for the instructions for installing the
Wheel Angle Sensor Mounting Brackets, installing the Wheel Angle Sensor, cutting the linkage
rods, connecting the linkage rods, and verifying the Wheel Angle Sensor is installed properly.
