Diagnostic Codes Table
J1939 Code and Description Conditions which Generate this Code System Response
632-5 Engine Fuel Shutoff Valve #1 : Current Below Normal The Electronic Control Module (ECM) detects a low current in the circuit for the GSOV for 2 seconds.
The output driver must be off for 5 seconds in order for this code to become active. The code is logged.
The amber warning lamp is illuminated.
The service tool displays "Error Indicator" on the status screen for this parameter.
632-6 Engine Fuel Shutoff Valve #1 : Current Above Normal While the output driver is on for 5 seconds, the ECM detected a high current in the circuit for the GSOV for one second. The code is logged.
The amber warning lamp is illuminated.
The service tool displays "Error Indicator" on the status screen for this parameter.
The output driver automatically resets and the output driver continues to try to activate the circuit component.
632-7 Engine Fuel Shutoff Valve #1 : Not Responding Properly The Engine Control Switch (ECS) is placed in the STOP position. The ECM has shut off the fuel to the engine, but the engine rpm remains above the crank terminate speed. The engine speed exceeded the crank terminate speed for a period that exceeds the "Engine Speed Drop Time". The code is logged.
The red stop lamp is illuminated.
The power to the GSOV remains in the de-energized state and the ECM removes ignition power from the engine. The ECM contains the logic and the outputs for control of starting the engine and stopping the engine. Some of the logic for starting the engine and for stopping the engine is customer programmable. The logic responds to inputs from the following components: engine control, emergency stop switch, remote start switch, data link and other inputs.The ECM outputs a signal in order to control the solenoid for the GSOV. To enable gas flow to the engine, the GSOV must be energized.The most likely cause of a diagnostic code is a poor electrical connection or a problem in a wiring harness. The next likely cause may be a problem with the solenoid. The least likely cause is a problem with the ECM.When the 632-7 Engine Fuel Shutoff Valve #1 : Failure occurs, the ECM assumes that the GSOV did not close. The ECM terminates the ignition. If the GSOV does not respond to the ECM command, unburned gas will remain in the air inlet and exhaust system.Note: Ensure that the unburned gas is purged from the exhaust before restarting the engine. Failure to purge the unburned gas from the engine may result in an explosion in the exhaust piping.The following information describes the systems operation when the GSOV is controlled by the ECM:The ECM sends an output signal to the solenoid for the GSOV that controls the operation of the GSOV. This output is energize-to-run. During the crank cycle, when the engine speed exceeds 50 rpm, the ECM provides a voltage of +Battery to the output for the GSOV. The solenoid becomes energized. As the valve opens, fuel begins to flow to the engine. The ECM removes the voltage from this output in order to stop the engine. The solenoid for the GSOV becomes de-energized. The fuel flow to the engine is stopped.

Schematic of the circuit for the GSOV
Note: Due to certain regulations for this application, the harness for the GSOV contains an unused shield circuit.Test Step 1. Inspect the Electrical Connectors and the Wiring
Remove the electrical power from the engine.

Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit for the GSOV.
Check the hex head bolt for each of the ECM connectors for the proper torque. Refer to Testing and Adjusting, "Electrical Connectors - Inspect" for the correct torque values.
Check the wiring harnesses for abrasion, for corrosion and for pinch points. Expected Result:All connectors, pins, and sockets are coupled and/or inserted. The harness and wiring are free of corrosion, of abrasion and of pinch points.Results:
OK - The harness and wiring appear to be OK. Proceed to Test Step 2.
Not OK - There is a problem in the wiring harness.Repair: Repair the connectors and/or the wiring. Replace parts, if necessary. Ensure that all of the seals are properly in place and ensure that the connectors are coupled. Verify that the problem is resolved.STOPTest Step 2. Check for Active Diagnostic Codes
Ensure that the electrical power has been removed from the engine.
Connect Cat ET to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools".
Restore the electrical power to the engine. Set the engine control to STOP. Note: The 632-5 Engine Fuel Shutoff Valve #1 : Current Below Normal can only be detected when the output for the start command is off. The output is normally off when the engine control is set to STOP and the engine speed is zero rpm.
