PAD AS 2136184 - Caterpillar

Conditions Which Generate This Code:The 05 diagnostic code indicates the engine shutdown without a shutdown command from the Status Control Module (SCM).Test Step 1. Check the Operation of the Governor, the Throttle and the Gas Valve
Turn the Engine Control Switch (ECS) to the MANUAL/START position.
Crank the engine.Note: If the engine will not crank, refer to Troubleshooting, "Engine Does Not Crank".
Check the operation of the governor, the throttle and the gas valve.Expected Result:The governor, the throttle and the gas valve are operating correctly.Results:
OK - The governor, the throttle and the gas valve are operating correctly. There may be a problem with the ignition or with the engine fuel system. Refer to the engine troubleshooting guide, if necessary. If this application utilizes a 2301A speed control, proceed to Test Step 4.
Not OK - The gas valve for the Energize to Run (ETR) fuel system is not operating correctly. Proceed to Test Step 2.
Not OK - The gas valve for the Energize to Shutdown (ETS) fuel system is not operating correctly. Proceed to Test Step 3.Test Step 2. Check the ETR
Turn the main disconnect switch to the OFF position.
Connect a jumper wire between terminal S and terminal 23 of the SCM.
Turn the main disconnect switch to the ON position.
Attempt to start the engine.Expected Result:The engine starts and the engine runs.Results:
OK - The engine starts and the engine runs.Repair: The Fuel Control Relay (FCR) was not energizing the Gas Shut Off Valve (GSOV). Refer to Testing and Adjusting, "Relay Module - Test".STOP
Not OK - The engine does not start.Repair: Troubleshoot the GSOV. Refer to the engine Troubleshooting, "Engine Cranks but Will Not Start".Check the voltage at terminal S. If there is no voltage at terminal S, measure the voltage at the battery posts. Check the wiring and/or connectors between the SCM and the battery.Repair the connectors or wiring and/or replace the connectors or wiring. Replace the battery, if necessary.Verify that the repair eliminates the problem.STOPTest Step 3. Check the ETS
Turn the main disconnect switch to the OFF position.
Remove the fuse F6 that is between terminal R and terminal S of the SCM.
Turn the main disconnect switch to the ON position.
Attempt to start the engine.Expected Result:The engine starts and the engine runs.Results:
OK - The engine starts and the engine runs.Repair: The FCR is energizing the GSOV. Check the FCR. Refer to Testing and Adjusting, "Relay Module - Test".STOP
Not OK - The engine does not start.Repair: Troubleshoot the GSOV. Refer to the engine Troubleshooting, "Engine Cranks but Will Not Start".Check the resistance between terminal S and terminal 23 of the SCM. If the resistance is below 5 Ohms, proceed to Testing and Adjusting, "Relay Module - Test".If the resistance is not below 5 Ohms, check the circuit for a short to the +Battery.If necessary, repair the connectors or wiring and/or replace the connectors or wiring. Verify that the repair eliminates the problem.STOPTest Step 4. Check the 2301A Speed Control
Measure the voltage on terminal 2 of the speed control.
Turn the main disconnect switch to the
