Connections of "Right Steering Cylinder" position sensor
This diagnostic code is associated with the "Right Steering Cylinder" position sensor. The position sensor provides a PWM input signal to the Implement ECM 2 and to the "Transmission/Chassis ECM". The FMI 00 diagnostic code means that the ECM is receiving a valid signal from the sensor that is above the high limit for the expected signal range.The sensor is a PWM sensor that operates at a frequency of approximately 500 Hz. The duty cycle of the PWM signal that is supplied to the ECM is measured in small increments. The changes in the duty cycle of the sensor cannot be measured with a digital multimeter.The possible causes of this diagnostic code are listed below:
Mechanical devices are broken or loose.
The sensor has failed.
The ECM has failed. A failure of the Transmission/Chassis ECM is unlikely.Note: Before performing this procedure, check for an active CID 0041 diagnostic code for the 8 VDC sensor power supply of the Implement ECM 2 (145). Correct any problem with the 8 VDC power supply before performing this procedure.Note: The "Transmission/Chassis ECM" (MID 027) and the Implement ECM 2 (MID 145) receive an input signal from the "Right Steering Cylinder" position sensor. Both ECM modules can activate a CID 2201 FMI 00 diagnostic code when the signal is above the normal range. When one of the ECM modules has an active CID 2201 FMI 00 diagnostic code and the other ECM does not have an active diagnostic code, it is likely that the sensor is operating correctly. When this occurs, a poor connection in the machine harness would be suspected. When both ECM modules have activated the diagnostic code, either the sensor or a harness problem could be the cause. If both ECM modules have activated the diagnostic code, it is unlikely that either ECM is the cause of the problem. For either condition, proceed with this procedure in order to verify the cause of the problem.Note: Before performing this procedure, inspect the harness connectors that are involved in the circuit. Poor connections are often the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, that all connections are secure and that all connections are in good condition. If a problem with a connection is found, correct the problem and verify that this diagnostic code is active before performing this procedure. Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear the diagnostic codes when the original diagnostic code has been corrected. Test Step 1. CHECK THE MECHANICAL CONNECTIONS
Turn the key start switch and the disconnect switch to the OFF position.
Visually inspect the mechanical connections for the "Right Steering Cylinder". Verify that all mechanical connections and adjustments for the steering cylinder are in good condition and verify that none of the mechanical connections are loose. Expected Result:All mechanical connections for the "steering cylinder" are in good condition and no mechanical connections are loose.Results:
OK
