Schematic Of The Hydraulic Oil Temperature SensorThis diagnostic code is associated with the hydraulic oil temperature sensor. This diagnostic code is recorded when the ECM reads the signal from the hydraulic oil temperature sensor (wire 404-YL) as being shorted to +battery. The signal (wire 404-YL) connects to contact J1-29 of the ECM.Possible causes of the diagnostic code is listed:
The return circuit is open.
The signal circuit is open or the sensor is disconnected.
The signal circuit is shorted to +battery.
The sensor has failed.
The ECM has failed. This is unlikely.Note: Ensure that CID 0600 FMI 03 is active. This procedure can cause new diagnostic codes to be recorded. Ignore these created diagnostic codes. When the procedure is completed, clear the created diagnostic codes.Test Step 1. CHECK FOR AN OPEN IN THE RETURN CIRCUIT.
Disconnect the negative battery cable and turn the key start switch to the OFF position.
The sensor remains disconnected from the machine harness.
Disconnect the machine harness connector J1 from the ECM.
At the machine harness connector for the sensor, measure the resistance from contact 2 (wire 200-BK) to ground.Expected Result:The resistance measurement should measure less than 5 ohms.Results:
OK - The resistance measurement is less than 5 ohms. The harness is correct.Repair: The ECM may have failed. It is unlikely that the ECM is faulty. Recheck the status of the diagnostic code. If the diagnostic code remains present, exit this procedure
