Schematic for the Tilt Lever Position Sensor This diagnostic code is recorded when the implement electronic control module (ECM) determines that the voltage for the tilt lever position sensor is too high. The signal wire for the tilt lever position sensor connects to connector contact J2-25 (wire H711-GN) of the ECM. The tilt lever position sensor is a 500 Hz PWM sensor.The possible causes for this diagnostic code are listed:
The signal circuit is shorted to the +battery circuit.
The sensor has failed.
The signal circuit is open.
The ground circuit is open.System Response:The machine response is listed:
The tilt function will be disabled until the diagnostic code is cleared. Also, the tilt lever must be recentered.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 is corrected. Note: Ensure that the diagnostic code is active.Test Step 1. CHECK FOR POWER AT THE SENSOR.
Do not disconnect the harness connector from the sensor.
Turn the key start switch and the disconnect switch to the ON position.
At the harness connector for the sensor, measure the voltage from contact 1 to contact 2. Use the 7X-1710 Multimeter Probes .Expected Result:The voltage is the system voltage.Results:
YES - The voltage is system voltage. Proceed to Test Step 2.
NO - The voltage is not system voltage. The + battery circuit in the machine harness has failed.Repair: Replace the machine harness or repair the machine harness. Stop.Test Step 2. CHECK FOR PROPER GROUND AT THE SENSOR.
The machine harness remains connected to the sensor.
Turn the key start switch and the disconnect switch
