How to End a Troubleshooting Session (required after any troubleshooting)

1. Reset the PCM as described.
2. Turn the ignition switch OFF.
3. Disconnect the OBD II scan tool or Honda PGM Tester from the DLC.

NOTE: The PCM is part of the immobilizer system. If you replace the PCM, it will have a different immobilizer code. In order for the engine to start, you must rewrite the immobilizer code with the Honda PGM Tester.
