"Steering Cylinder" position sensor
When one of the "steering cylinder" position sensors on the machine has been replaced, two setup parameters must be changed in order for the Implement ECM to correctly control the cylinder operation.This procedure is to be performed when a "steering cylinder" position sensor is replaced in a hydraulic steering cylinder that has previously been in operation on the machine. When the complete hydraulic "steering cylinder" group is replaced, refer to the Testing and Adjusting, RENR9013, "New Steering Cylinder Group (Set)" for the setup procedure.For removal and replacement of the position sensor from the hydraulic "steering cylinder", refer to Disassembly and Assembly, RENR9704, "Clevis Style Cylinder Sensor - Remove and Install". Note: This procedure will require the use of the Caterpillar Electronic Technician (ET) service tool.MANUAL INSTALLATION OF STEERING CYLINDER POSITION SENSOR SETUP PARAMETERS

Steering cylinder with new position sensor connected at head end with portable hydraulic pump attached
The disconnect switch and the key start switch are in the OFF position. Cat ET is connected to the machine service connector.
After the new position sensor has been installed in the steering cylinder, fasten the cylinder to the machine at the cylinder head end only. Do not attach the rod end of the cylinder to the machine. Allow enough space for full extension of the cylinder rod.
Connect the correct connector of the machine wiring harness to the connector of the new position sensor for the steering cylinder.
Connect a portable hydraulic pump, a hand hydraulic pump, compressed air or a similar device to the hydraulic connectors of the cylinder that will enable manual retraction and extension of the cylinder.
Fully retract the cylinder rod to the mechanical stop of the cylinder.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.

Implement ECM Status Screen
In the Cat ET Status screen for the Implement ECM, look under the "Joystick Steering 2" group. With the cylinder rod at full retraction, record the duration of the pulse of the "steering cylinder" position sensor that is listed for the position sensor that was replaced. Example: (Left/ Right) Steering Cylinder Position Sensor Pulse Duration.
Use the portable device that is connected to the cylinder to manually move the cylinder rod to full extension to the mechanical stop of the cylinder.
In the Cat ET Status screen for the Implement ECM, look under the "Joystick Steering 2" group. With the cylinder rod at full extension, record the duration of the pulse of the "steering cylinder" position sensor of the "(Left/ Right) Steering Sensor Cylinder Position Sensor Pulse Duration".

Cat ET - Implement Configuration\Steering Parameters screen
The two new values that were recorded for the cylinder rod retraction and extension must now be entered using Cat ET. Follow the steps:
In Cat ET, select the "Implement Configuration Tool", then select "Steering Parameters".
Select the parameter that needs to be changed. Example: If the left hand position sensor has been replaced, one at a time select and change "Left Steering Cylinder Position Sensor Maximum Pulse
