Schematic for the Tilt Linkage Position Sensor
This 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 H711-GN(Green)) of the ECM.The possible causes of this diagnostic code are listed:
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:
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 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
