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

Reset the ECM/PCM with the HDS.
Do the ECM/PCM idle learn procedure (see FUEL LINE/QUICK-CONNECT FITTING PRECAUTIONS ).
Turn the ignition switch to LOCK (0).
Disconnect the HDS from the DLC.
NOTE: The ECM/PCM is part of the immobilizer system. If you replace the ECM/PCM you must use the HDS to instruct the new ECM/PCM and the immobilizer-keyless control unit to recognize each other's unique serial code.
