  1. Honda diagnostic system (HDS) tablet tester
  2. Honda interface module (HIM) and iN workstation with the latest HDS software version
  3. HDS pocket tester
  4. GNA600 and iN workstation with the latest HDS software version

Any one of the above updating tools can be used.

Note. Make sure the HDS/iN workstation has the latest HDS software version. Before you update the PCM, make sure the battery in the vehicle is fully charged, and connect a jumper battery (not a battery charger) to maintain system voltage. Never turn the ignition switch to LOCK (0) or ACC (I) during the update. If there is a problem during the update, leave the ignition switch ON (II). To prevent PCM damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, moonroof (if equipped), door locks, etc.) during the update. To ensure the latest program is installed, do a PCM update whenever the PCM is substituted or replaced. You cannot update a PCM with a program it already has. It will only accept a new program. High temperature in the engine compartment might cause the PCM to become too hot to run the update. If the engine was running before this procedure, open the hood, and cool the engine compartment. If you need to diagnose the Honda interface module (HIM) because the HIM's red (#3) light came on or was flashing during the update, leave the ignition switch in ON (II) when you disconnect the HIM from the data link connector (DLC). This will prevent PCM damage.

  1. Turn the ignition switch to ON (II), but do not start the engine.
  2. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
  3. Make sure the HDS communicates with the PCM and all other vehicle systems. If it doesn't, go to «DLC CIRCUIT TROUBLESHOOTING»(ref-333558-S02093989162009072100000) . If you are returning from DLC circuit troubleshooting, skip steps 4 and 5 , and clean the throttle body (see «THROTTLE BODY CLEANING»(ref-333563-S07939488122009072100000) ) after updating the PCM.
  4. Select the INSPECTION MENU with HDS.
  5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS HDS prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue this procedure.
  6. Exit the HDS diagnostic system, then select the update mode, and follow the HDS prompts to update the PCM.
  7. If the software in the PCM is the latest, disconnect the HDS/HIM from the DLC, and go back to the procedure that you were doing. If the software in the PCM is not the latest, follow the instructions on the HDS. If prompted to choose the PGM-FI system or the A/T system, make sure you update both. NOTE: If the PCM update system requires you to cool the PCM, follow the instructions on HDS. If you have a problem during the update (programming takes over 15 minutes, status bar goes over 100%, the D or immobilizer indicator flashes, HDS tablet freezes, etc.), follow these steps to minimize the chance of damaging the PCM. Leave the ignition switch in ON (II). Connect a jumper battery (do not connect a battery charger). Shut down the HDS. Disconnect the HDS from the DLC. Reboot the HDS. Reconnect the HDS to the DLC, and do the update again.
  8. If the TP POSITION CHECK failed in step 5, clean the throttle body (see «THROTTLE BODY CLEANING»(ref-333563-S07939488122009072100000) ).
  9. Do «PCM IDLE LEARN PROCEDURE»(ref-333561-S36442749152009072100000) ).
  10. Do the CKP pattern learn procedure (see «CKP PATTERN CLEAR/CKP PATTERN LEARN»(ref-333557-S25100768752009072100000) ).
  1. Honda diagnostic system (HDS) tablet tester
  2. Honda interface module (HIM) and iN workstation with the latest HDS software version
  3. HDS pocket tester
  4. GNA600 and iN workstation with the latest HDS software version

  1. Connect 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 all other vehicle systems. If it doesn't, go to «DLC CIRCUIT TROUBLESHOOTING»(ref-333558-S02093989162009072100000) . If you are returning from the DLC circuit troubleshooting, skip steps 5 through 9 , 18 through 23 , and 26 through 28 , and do these procedures after replacing the PCM: Replace the engine oil (see «ENGINE OIL REPLACEMENT»(ref-333553-S35525073332009072100000) ) and the engine oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-333553-S34491408782009072100000) ). Replace the ATF (see «ATF REPLACEMENT»(ref-333568-S25714344582009072100000) ). Clean the throttle body (see «THROTTLE BODY CLEANING»(ref-333563-S07939488122009072100000) ).
  4. Select the PGM-FI system with the HDS.

  7. Select the REPLACE PCM MENU, then select READ DATA, and follow the HDS prompts. NOTE: Doing this step copies (READS) the engine oil life data from the original PCM so you can later download (WRITES) it into the new PCM. If READ DATA indicates FAILED, continue with this procedure.
  8. Select the A/T system with the HDS.
  9. Select the REPLACE TCM/PCM MENU, then select READ DATA, and follow the HDS prompts. NOTE: Doing this step copies (READS) the ATF life data from the original PCM so you can later download (WRITES) it into the new PCM. If READ DATA indicates FAILED, continue with this procedure.

  15. Install the PCM in the reverse order of removal.
  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 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 HDS prompts. NOTE: If the WRITE DATA indicates FAILED, continue with this procedure.

  22. Select the AT SYSTEM with the HDS.
  23. Select the REPLACE TCM/PCM MENU, then select WRITE DATA, and follow the HDS prompts. NOTE: If the WRITE DATA indicates FAILED, continue with this procedure.
  24. Select IMMOBI SYSTEM with the HDS.
  25. Enter the immobilizer code with the PCM replacement procedure in the HDS; it allows you to start the engine.
  26. If the TP POSITION CHECK failed in step 6, clean the throttle body (see «THROTTLE BODY CLEANING»(ref-333563-S07939488122009072100000) ), then Go to step 27 .
