Rimpull Control Position Sensor locationThis diagnostic code is associated with the Rimpull Control Position Sensor. This diagnostic code is recorded when the ECM reads the sensor signal as being below normal.Conditions that could cause this diagnostic code to be activated are listed below:
The supply wire to the sensor is open.
The signal circuit is shorted to ground.
The sensor has failed.
The ECM has failed. This is unlikely. Note: Before performing this procedure, inspect the harness connectors that are involved in the circuit. Poor connections can often be 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. Clear any created diagnostic codes after the original diagnostic code has been corrected.System Response:A Level 1 warning will be generated. The feature is disabled.Test Step 1. CHECK THE SENSOR.
Turn the disconnect switch and the starter keyswitch to the ON position.
Ensure that the diagnostic code is active.
Disconnect the sensor from the machine harness.
Observe the status of the diagnostic code. Expected Result:The diagnostic code will remain active.Results:
OK - The diagnostic code remains active. The sensor has not failed. The machine harness may have failed or the ECM may have failed. Proceed to test step 2.
NOT OK - The diagnostic code is NO longer active. The sensor has failed.Repair: Temporarily connect a new sensor to the harness. Do not install the sensor. Verify that the replacement sensor has cleared the CID 2717 FMI 04 code. If the code is no longer active, permanently install the new sensor.STOPTest Step 2. CHECK THE SIGNAL CIRCUIT FOR A SHORT TO GROUND.
The sensor remains disconnected from the machine harness.
Turn the starter keyswitch and the disconnect switch to the OFF position.
Disconnect the J1 and J2 machine harness connector from the ECM.
At the J2 machine harness connector, measure the resistance from contact J2-35 (wire E989-WH) to all contacts that are used in the machine harness connectors for the ECM.Expected Result:The resistance is greater than 5000 ohms for each measurement.Results:
OK - The resistance is greater than 5000 ohms for each measurement.Repair: Ensure that you have the latest version of software for your specific machine and ECM. Refer to the Testing and
