1. Turn the ignition off to the lock position.
2. Remove all test equipment.
3. Connect all previously disconnected components and connectors.
4. Verify all accessories are turned off, the battery is fully charged and the charging system has a status of "recharging".
5. Verify that the ignition is on. With the scan tool, record and erase all DTCs from all modules. Start the engine and allow it to run for two minutes and fully operate the system that was indicating the failure.

NOTE: Turn the steering wheel from lock to lock, holding at each lock position for One second.

6. Turn the ignition off and wait five seconds. Turn the ignition on and using the scan tool, read Diagnostic Trouble Codes (DTCs) from all modules.

8. Again, with the scan tool read DTCs. Diagnose and repair the DTC(s).
