Typical fuel control relay (1) Connector for the fuel control relay (2) Relay
Disconnect connector (1) from relay (2) .
Set the engine control to the STOP mode.
Use Cat ET to clear the logged "17-06 Fuel Shutoff Valve short to ground" diagnostic code.
To prevent the engine from starting, shut OFF the main gas supply.Note: To provide the output for the fuel control relay, the sequence for engine start-up must be initiated. Otherwise, a "17-06 Fuel Shutoff Valve short to ground" diagnostic code cannot be generated.
Set the engine control to START for at least six seconds. Then set the engine control to the STOP mode.
Use Cat ET to look for a logged "17-06 Fuel Shutoff Valve short to ground" diagnostic code again.Expected Result:A "17-06 Fuel Shutoff Valve short to ground" was not generated.Results:
OK - When the relay was connected, a "short to ground" diagnostic code was generated. When the relay was disconnected, no "short to ground" diagnostic code was generated. There is a problem with the relay.Repair: Perform the following procedure:
Set the engine control to the OFF/RESET mode. Switch the 16 amp circuit breaker OFF.
Inspect the relay's connectors for damage and/or for corrosion.
Make repairs, as needed.If the problem is not resolved, replace the relay.STOP
Not OK - A "short to ground" diagnostic code was generated when the relay was disconnected. Proceed to Test Step 9.Test Step 9. Create an Open Circuit at the Terminal Box for the Master ECM
Set the engine control to the OFF/RESET mode. Switch the 16 amp circuit breaker OFF.
Disconnect connector P13 from the terminal box.
Switch the 16 amp circuit breaker ON. Set the engine control to the STOP mode.

OK - A "17-06 Fuel Shutoff Valve short to ground" diagnostic code was not generated when the P13 connector was disconnected. There is a problem in the engine harness.Repair: Perform the following procedure:
Set the engine control to the OFF/RESET mode. Switch the 16 amp circuit breaker OFF.
Reconnect the P13 connector.
Repair the engine harness, when possible. Replace the harness, if necessary.STOP
Not OK - A "17-06 Fuel Shutoff Valve short to ground" diagnostic code was generated when the P13 connector was disconnected. There is probably a short circuit to ground in the terminal box.Repair: Reconnect the P13 connector. Proceed to Test Step 10.Test Step 10. Check the Master ECM
Set the engine control to the OFF/RESET mode. Switch the 16 amp circuit breaker OFF.
