2. Connect the HDS to the DLC (A) located behind the driver's dashboard lower cover.
3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting. If you did the DLC circuit troubleshooting, skip steps 5 thru 9, then clean the throttle body after substituting the PCM.

12. Install the PCM and the battery in the reverse order of removal.
13. Turn the ignition switch to ON (II).
NOTE: DTC P0630 "VIN not Programmed or Mismatch" will be stored because VIN has not been programmed into the PCM. Ignore it, and continue this procedure.
14. Input the VIN to the PCM with the HDS.
15. Update the PCM if it does not have the latest software.
16. Select the IMMOBILIZER SYSTEM with the HDS.
17. Enter the immobilizer code with the PCM replacement procedure in the HDS; this allows you to start the engine.
