Connections of the tilt lever position sensor
The diagnostic code is associated with the tilt lever position sensor. The diagnostic code is recorded when the ECM has determined that the voltage of the circuit for the sensor is below normal.The possible causes for this diagnostic code are listed:
The sensor supply circuit to the sensor is shorted to ground.
A sensor has failed.
The ECM has failed. This is unlikely.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. Ensure that the diagnostic code of CID 0353 FMI 04 is active before performing this procedure.Note: Use the digital multimeter for the measurements in this procedure.System Response:The tilt function will be disabled until the diagnostic code is cleared. The tilt lever position sensor must be centered.Test Step 1. CHECK THE SENSOR
Turn the disconnect switch and the key start switch to the ON position.
Ensure that the diagnostic code is active.
Observe the status of the diagnostic code. Disconnect the sensor from the machine harness. Expected Result:The diagnostic code remains active.Results:
OK - The diagnostic code remains active. The sensor is correct. Proceed to Test Step 2.
NOT OK - The diagnostic code is no longer active. The sensor has failed.Repair: Replace the sensor. See Testing and Adjusting, KENR5177, "Calibration" for more information. Verify that the new sensor corrects the problem.STOPTest Step 2. CHECK THE SIGNAL CIRCUIT FOR A SHORT TO GROUND.
The sensor remains disconnected from the machine harness.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the J1 and J2 machine harness connector from the ECM.
At the J1 machine harness connector, measure the resistance from contact J2-33 (wire H711-GN(Green)) 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: If the cause of the problem is not found, contact your dealership for possible consultation with Caterpillar. This consultation may greatly reduce repair time. If the ECM requires replacement, see Troubleshooting, "Electronic Control Module (ECM) - Replace".STOP
NOT OK - The resistance is less than 5000 ohms for one or more of the measurements.Repair: The machine harness has failed. There is a short in the machine harness between the signal circuit and ground. Repair the machine harness or replace the machine harness.STOP
