Schematic for the Tilt Linkage Position SensorThis diagnostic code is recorded when the Implement ECM determines that the voltage for the Tilt Linkage Position Sensor is below normal. The Tilt Linkage Position Sensor is a PWM sensor. The signal wire for the tilt linkage position sensor connects to connector contact J2-33 (wire 762-YL) of the Implement ECM.The possible causes of this diagnostic code are listed below:
A shorted harness
An open circuit in the power supply wiring for the tilt linkage position sensor
A failed sensor
The ECM may have failed. This is unlikely.System Response:The machine response is listed below:
The tilt features will not work.
The active diagnostic code must be removed before the implement features will work properly.Note: Ensure that the diagnostic code is active and that the diagnostic code indicator is active.Note: The following procedure can create numerous related diagnostic codes. Reconnect all harnesses. Then, the related diagnostic codes will be shown as being NOT active. Complete the following procedure. Then, clear all of the related diagnostic codes.Test Step 1. CHECK THE SIGNAL CIRCUIT FOR A SHORT TO GROUND.
The sensor remains disconnected from the harness.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the harness connector J1 and J2 from the Implement ECM.
Measure the resistance from J2-33 (wire 762-YL) to all possible sources of ground.Expected Result:The resistance should be greater than 5000 ohms.Results:
YES - The resistance is greater than 5000 ohms. The harness is correct. Proceed to Test Step 2.
NO - The resistance is less than 5000 ohms. There is a short in the harness. The short is between the signal wire 762-YL and a ground source.Repair: Repair the harness or replace the harness.STOPTest Step 2. CHECK THE SENSOR.
Turn the disconnect switch and the key start switch to the ON position.
Observe the status of the diagnostic code. Then, disconnect the harness from the sensor.Expected Result:The diagnostic code remains active.Results:
YES
