Schematic of the right front drive motor speed sensorThis diagnostic code is recorded when there is no signal from either input of the right speed sensors in the manual mode.The following conditions could cause this diagnostic code to be activated:
The power wire (T800-OR) for the sensor is open.
The return wire (J767-GY) for the sensor is open.
The return wire (J767-GY) for the sensor is shorted to the + battery circuit.
The signal wire (J718-OR) is open.
The signal wire (J718-OR) is shorted to the + battery circuit.
The signal wire (J718-OR) is shorted to ground.
The sensor is faulty.
The right drive pump has failed.
The right charge pump has failed.
The charge pressure is low.
The input gears of the pump have failed or the shaft has failed.
Failure of the ECM is unlikely.Test Step 1. VISUALLY VERIFY THAT THE FRONT WHEELS ARE SPINNING
Select forward direction. Select maximum "Creep" speed.
Engage "AWD Creep mode" and lower the blade in order to lift the front wheels off the ground.
Verify that the green AWD indicator is illuminated.
Select reverse direction. Select maximum "Creep" speed.
Engage "AWD Creep mode" and lower the blade in order to lift the front wheels off the ground.
Verify that the green AWD indicator is illuminated.Expected Result:Both front wheels turn in both forward and reverse directions in "Creep mode". The green AWD indicator should illuminate.Results:
Green AWD Indicator does not activate. - Check ET for other active AWD diagnostics or events. Clear the diagnostic codes that are active.
