    Special Tools Required 

    • Honda diagnostic system (HDS) tablet tester
    • Honda interface module (HIM) and an IN workstation with HDS and CM update software
    • HDS pocket tester
    • GNA600 and an IN workstation with HDS and CM update software

      Use any one of these update tools.

  2. Turn the ignition switch to ON (II).
  3. Make sure the HDS communicates with the PCM. If it doesn't, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ). If you are returning from the DLC circuit troubleshooting, skip steps 5 to 6, and clean the throttle body after substituting the PCM (see THROTTLE BODY CLEANING ).
  4. Select the INSPECTION MENU with the HDS.
  5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS screen prompts.
    NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure.
  6. Turn the ignition switch to LOCK (0).
  7. Do the battery removal procedure (see REMOVAL
  8. Remove the bracket (D), then free the A/C discharge line from the clip (E). Remove the A/C suction line mounting bracket bolt (F).

  10. Install the PCM and battery cables in the reverse order of removal.
  11. Do the battery installation procedure (see INSTALLATION
  12. Turn the ignition switch to ON (II).
    NOTE: If DTC P0630 "VIN not Programmed or Mismatch" will be stored because the VIN has not been programmed into the PCM; ignore it, and continue this procedure.

  14. Update the PCM if it does not have the latest software.
  15. Select the IMMOBI SYSTEM with the HDS.
  16. Enter the immobilizer code using the PCM replacement procedure in the HDS; this allows you to start the engine.
  17. Reset the PCM with the HDS.
  18. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS screen prompts. If the TP POSITION CHECK failed, clean the throttle body (see THROTTLE BODY CLEANING ).
