PCM Replacement

Special Tools Required

  1. Honda diagnostic system (HDS) tablet tester
  2. Honda interface module (HIM) and an iN workstation with HDS and CM update software
  3. HDS pocket tester
  4. GNA600 and an iN workstation with HDS and CM update software

Use any one of these update tools.

Note. Make sure the HDS has the latest software version. If you are replacing the PCM after substituting a known-good PCM, reinstall the original PCM, then do this procedure. During the procedure, if any READ DATA, WRITE DATA, or other data checks fail, note the failure, then continue.

  1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
  2. Turn the ignition switch to ON (II).
  3. Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting (see «DLC CIRCUIT TROUBLESHOOTING»(ref-348508-S35625078472009112400000) ). If you are returning from DLC circuit troubleshooting, skip step s 4 through 9,17 through 19, 22, and 23, then do this after replacing the PCM: Replace the engine oil (see «ENGINE OIL LEVEL CHECK»(ref-348509-S26677371102009112400000) ) and the engine oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-348509-S20143541072009112400000) ). Clean the throttle body (see «THROTTLE BODY CLEANING»(ref-348519-S42264851032009112400000) ).
  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 PCM MENU, then select READ DATA, and follow the screen prompts. NOTE: Doing this step copies (READS) the engine oil life data from the original PCM so you can later download (WRITE) it into the new PCM. If the READ DATA indicates FAILED, continue with this procedure.
  8. Turn the ignition switch to LOCK (0).
  9. Do the battery terminal disconnection procedure (see «BATTERY TERMINAL DISCONNECTION AND RECONNECTION»(ref-348526-S32567287482009112400000) ).
  10. Remove the front console covers (A) (see «CENTER CONSOLE REMOVAL/INSTALLATION»(ref-348541-S05967894302009112400000) ), and pull back the carpet.
  11. Remove the ducts (B).
  12. Disconnect the PCM connectors (C).
  13. Remove the bolts (D), then remove the PCM (E).
  14. Install the parts in the reverse order of removal.
  15. Do the battery terminal reconnection procedure (see «BATTERY TERMINAL DISCONNECTION AND RECONNECTION»(ref-348526-S32567287482009112400000) ).
  16. Turn the ignition switch to ON (II).
  17. Manually input the VIN to the PCM with the HDS. NOTE: DTC P0630 "VIN Not Programmed or Mismatch" may be stored because the VIN has not been programmed into the PCM, ignore it, and continue this procedure.
  18. If the READ DATA (engine oil life) failed in step 7, go to step 21 . Otherwise, go to step 19.
  19. Select the PGM-FI system with the HDS.
  20. Select the REPLACE PCM MENU, then select WRITE DATA and follow the screen prompts. NOTE: If the WRITE DATA indicates FAILED, continue this procedure.
  21. Select IMMOBI system with the HDS.
  22. Enter the immobilizer code with the PCM replacement procedure in the HDS; it allows you to start the engine.
  23. If the TP POSITION CHECK failed in step 6, clean the throttle body (see «THROTTLE BODY CLEANING»(ref-348519-S42264851032009112400000) ), then go to step 24.
  24. If the READ DATA failed in step 7 or the WRITE DATA failed in step 20, replace the engine oil (see «ENGINE OIL LEVEL CHECK»(ref-348509-S26677371102009112400000) ) and engine oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-348509-S20143541072009112400000) ), then go to step 25.
  25. Select PGM-FI system, and reset the PCM with the HDS.
  26. Update the PCM if it does not have the latest software (see «PCM UPDATE»(ref-348508-S21120732372009112400000) ).
  27. Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-348529-S13364648212009112400000) ).
  28. Do the CKP pattern learn procedure (see «HDS CLEAR COMMAND»(ref-348507-S11151874542009112400000) ).
