TRACK AS 3448848 - Caterpillar

Do not start the engine when performing this step. If the engine is started, any change in joystick position will result in steering to maximum wheel angle. Steering to maximum wheel angle may result in severe injury or death.
Mark the harness connector for the right steering sensor.
Disconnect the machine harness connector from the position sensor of the right steering cylinder.
Disconnect the machine harness connector from the position sensor of the left steering cylinder.
Connect the marked connector for the right steering sensor to the connector for the left steering sensor.
Connect the unmarked connector for the left steering sensor to the connector for the right steering sensor.
Turn the disconnect switch to the ON position.
Turn the key start switch to the ON position.Note: Do not start the engine.
Observe the status of the active diagnostic code for the right steering sensor.Expected Result:When the harness connectors are switched, the CID 2201 FMI 08 diagnostic code for the right steering sensor is not active. A CID 2200 FMI 08 diagnostic code for the left steering sensor is now active.Results:
OK - The CID 2201 FMI 08 diagnostic code is no longer active. A CID 2200 FMI 08 diagnostic code is now active. The sensor has failed.Repair: The position sensor of the right steering cylinder is the cause of the problem. Replace the position sensor of the right steering cylinder.BEFORE REPLACING THE STEERING POSITION SENSOR, RECONNECT THE HARNESS CONNECTORS TO THE CORRECT CONNECTORS FOR THE STEERING SENSOR.For removal of the position sensor from the steering cylinder, refer to the Disassembly and Assembly, RENR9704, "Clevis Style Cylinder Sensor - Remove and Install" Story.After replacement of the sensor, the parameters of the new position sensor MUST be entered in Cat ET before the machine can be operated. Refer to the Testing and Adjusting, "Position Sensor (Steering Cylinder) - Set" Story in this manual for the correct procedure.STOP
NOT OK - The status of the CID 2201 FMI 08 diagnostic code did not change when the sensor connectors were switched. The CID 2201 FMI 08 diagnostic code is still active. There is a problem in the machine harness.
ENSURE THAT THE MACHINE HARNESS CONNECTORS ARE CONNECTED TO THE CORRECT POSITION SENSOR. THE MARKED HARNESS CONNECTOR IS CONNECTED TO THE RIGHT STEERING SENSOR. THE UNMARKED HARNESS CONNECTOR IS CONNECTED TO THE LEFT STEERING SENSOR. Proceed to Test Step 3.Test Step 3. CHECK FOR AN OPEN IN THE SIGNAL CIRCUITBefore performing this Test Step, verify that the machine harness connectors are properly connected in the original positions.
Turn the disconnect switch to the OFF position.
Turn the key start switch to the OFF position.
Disconnect the machine harness connector from the position sensor of the right steering cylinder.
At the machine harness connector for the right steering sensor, place a jumper wire between return contact 2 (wire P967-PU) and signal contact 3 (wire H765-WH).
Disconnect the machine harness connectors J1 and J2 from the Implement ECM 2 and from the Transmission/Chassis ECM.
At the Implement ECM 2, measure the resistance from return contact J1-45 (wire P967-PU) to signal
