Schematic of the Solenoid for the Engine/Fuel shutdown SolenoidThis diagnostic code is recorded when the ECM reads the current of the solenoid as being below normal.The possible causes are listed:
There is an open in the circuit.
The solenoid has failed.
The ECM has failed. This is unlikely.Note: The following procedure can create numerous related diagnostic codes. When all harnesses are reconnected, the related diagnostic codes will be shown as being not active. Clear all related diagnostic codes after this procedure is completed.Test Step 1. CHECK THE SOLENOID.
Turn the disconnect switch and the key start switch to the ON position. DO NOT start the engine.
Disconnect the machine harness from the solenoid.
At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire 327-PK) to frame ground.
Observe the status of the diagnostic code.Expected Result:The diagnostic code is active. Then, the diagnostic code is NOT active as the jumper wire is installed and removed. Results:
YES - The circuit is correct. The solenoid has failed.Repair: Repeat this test "CHECK THE SOLENOID" in order to verify that the solenoid has failed. Replace the solenoid.STOP
NO - The diagnostic code remains active. Proceed to test step 2.Test Step 2. CHECK THE SOLENOID CIRCUIT FOR AN OPEN.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the J2 machine harness connector from the ECM.
At the machine harness connector for the solenoid, the jumper wire remains installed.
At J2 machine harness connector, measure the resistance from contact J2-6 (wire 327-PK) to frame ground.. Expected Result:The resistance should be less than 5 ohms.Results:
YES - The resistance is less than 5 ohms. The machine harness is correct. Proceed to test step 3.
NO - The resistance measurement is NOT correct. There is an open circuit in the machine harness.Repair: The open is in the wire for the solenoid signal or in the ground circuit of the solenoid. Repair the machine harness or replace the machine harness. Repair or replace the ground circuit for the solenoid.STOPTest Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Inspect the contacts and clean the contacts of the harness connectors.
Reconnect all harness connectors.
Turn the disconnect switch and the key start switch to the ON position.
Clear all inactive diagnostic codes.
Operate the machine.
Stop the machine and place the parking brake switch in the ON position.
Check if the diagnostic code for the solenoid is active.Expected Result:The diagnostic code is NO longer active. Results:
YES - The diagnostic code is NO longer active. The diagnostic code does not exist at this time. Repair: The initial diagnostic code was probably caused by a poor electrical connection or a short at one of the harness connectors that was disconnected and reconnected. Resume normal machine operation.STOP
NO - The diagnostic code has not been corrected. The ECM may have failed.Repair: It is unlikely that the ECM has failed. Exit this procedure and perform this procedure again. Also, recheck if the diagnostic indicator is illuminated for this diagnostic code. If the cause of the diagnostic code is not found, replace the ECM.
