Verification

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reconnect the connectors, components, etc.
- Run the starter motor/start the engine.
- Allow the engine to idle if it starts.
- Read the diagnostic status and fault status for the diagnostic trouble code by selecting the diagnostic trouble code in the list.
Check the fault status for the diagnostic trouble code when the scan is "Implemented". When the function is correct the fault status should be "No fault found" when the scan is implemented.





Is the function OK?

Yes - Troubleshooting procedure complete
