Connections of the 5 Volt Supply
The sensor supply is a power supply that is internal to the ECM. The sensor supply provides 5 VDC in order to operate the oil temperature sensor. The ECM monitors the sensor supply voltage for a high voltage condition. If the voltage rises above 7 VDC for 1 second, a diagnostic code will be generated. The active diagnostic code is cleared when the voltage drops below 6 VDC for 5 seconds.This diagnostic code will be recorded when the ECM reads the voltage for the circuit of the sensor supply as being above normal.The results of this diagnostic code are listed:
All of the associated sensors will also log diagnostic codes.
When this diagnostic code occurs, the action lamp and the action alarm are ON.The possible causes of the diagnostic code are listed:
The supply circuit (wire R977-OR(Orange)) is shorted to the +battery circuit in the machine harness.
The ECM has failed. This is unlikely.Test Step 1. CHECK FOR A SHORT TO THE +BATTERY CIRCUIT.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness from the ECM.
Perform the following measurement at the connectors of the ECM. Measure the resistance between the contacts for the +battery and the contact for the sensor supply voltage. Expected Result:The resistance that is measured should be greater than 5000 ohms.Results:
OK - The resistance measurement is greater than 5000 ohms. The harness circuit is correct. The ECM may have failed.Repair: It is unlikely that the ECM has failed. Perform this diagnostic code again. Replace the ECM if the cause of the diagnostic code is NOT found. See Testing and Adjusting, "Electronic Control Module (ECM) - Replace". STOP
NOT OK - The resistance measurement is less than 5000 ohms. Repair: The machine harness has failed. There is a short between the +battery circuit and the circuit for the sensor power supply in the machine harness. Repair the machine harness or replace the machine harness.STOP
