  2. Turn the ignition switch ON (II).
  3. Make sure the HDS communicates with the ECM/PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting; '06 model (see DLC CIRCUIT TROUBLESHOOTING  ), '07-08 models (see '07-08 MODELS  ). If you are returning from DLC circuit troubleshooting, skip steps 4 through  7,  17 through  19, and  22 through  23, and do the following procedures after replacing the ECM/PCM;
  4. Select the PGM-FI system with the HDS.
  5. Select the INSPECTION MENU with the HDS.
  6. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the screen prompts.
    NOTE: If the TP POSITION CHECK indicates FAILED, continue with this procedure.
  7. Select the REPLACE ECM/PCM MENU, then READ DATA and follow the screen prompts.
    NOTE:
    • Doing this step copies (READS) the engine oil life data from the original ECM/PCM so you can later download (WRITES) it into the new ECM/PCM.
    • If READ DATA indicates FAILED, continue with this procedure.
  8. Turn the ignition switch OFF.
  9. Jump the SCS line with the HDS.
  10. Remove the center lower covers (A).

  11. Remove the duct (B).
  12. Disconnect ECM/PCM connectors (C).
  13. Remove the bolts (D), then remove the ECM/PCM (E),
  14. Install the parts in the reverse order of removal.
  15. Turn the ignition switch ON (II).
  16. Manually input the VIN to the ECM/PCM with the HDS.
    NOTE: DTC P0630 "VIN Not Programmed or Mismatch" may be stored because the VIN has not been programmed into the ECM/PCM; ignore it, and continue this procedure.
  17. If the READ DATA (engine oil life) failed in step  7, go to step  20. Otherwise, go to step 18.
  18. Select the PGM-FI system with the HDS.
  19. Select the REPLACE ECM/PCM MENU, then WRITE DATA and follow the screen prompts.
    NOTE: If the WRITE DATA indicates FAILED, continue with this procedure.
  20. Select IMMOBI system with the HDS.
  21. Enter the immobilizer code with the ECM/PCM replacement procedure in the HDS; it allows you to start the engine.
  22. If the TP POSITION CHECK failed in step  6 clean the throttle body (see THROTTLE BODY CLEANING ), then go to step 23.
  23. If the READ DATA failed in step  7 or the WRITE DATA failed instep  19, replace the engine oil (see ENGINE OIL REPLACEMENT ) and engine oil filter (see ENGINE OIL FILTER REPLACEMENT ), then go to step 24.
  24. Select PGM-FI system and reset the ECM/PCM with the HDS.
  25. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ).
  26. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).
  27. Do the CKP pattern learn procedure (see CRANK (CKP) PATTERN CLEAR/CRANK (CKP) PATTERN LEARN ).
