Use this procedure when you have to update the PCM during troubleshooting procedures.

1. Turn the ignition switch 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 other vehicle systems. 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 4 and 5 and clean the throttle body after updating the
PCM.

4. Select the INSPECTION MENU with the HDS.

5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the screen prompts with

the HDS.

NOTE:



Make sure the HDS/HIM has the latest software version.



Before you update the PCM, make sure the battery in the vehicle is fully
changed.



Never turn the ignition switch OFF during the update. If there is a
problem with the update, leave the ignition switch ON.



To prevent PCM damage, do not operate anything electrical (headlights,
audio system, brakes, A/C, power windows, door locks, etc.) during the
update.



To ensure the latest program is installed, do an 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.



If you need to diagnose the Honda interface module (HIM) because the
HIM's red (#3) lamp came on or was flashed during the update, leave
the ignition switch in the ON (II) position when you disconnect the HIM
from the data link connector (DLC). This will prevent PCM damage.

6. Exit the HDS, then select the update mode, and follow the screen 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 screen. If prompted to choose the PGM-FI system or the A/T system, make sure you update both.

8. If the TP POSITION CHECK failed in step 5, clean the throttle body (see THROTTLE BODY

CLEANING ).

9. Do the PCM idle learn procedure (see PCM IDLE LEARN PROCEDURE ).

10. Do the CKP learn procedure.

SUBSTITUTING THE PCM

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



GNA-600 and an iN workstation with HDS and CM update software

Use this procedure when you have to substitute a known-good PCM during troubleshooting procedures.

1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the

dashboard.

NOTE:

If the TP POSITION CHECK indicates FAILED, continue this procedure.

NOTE:

If the PCM update system requires you to cool the PCM, follow the
screen prompts. If you run into a problem (programming takes over 15
minutes, status bar goes over 100%, D or immobilizer light flashes, HDS
tablet freezes, etc.) during the update procedure, follow these steps to
minimize the chance of damaging the PCM:



Leave the ignition switch in the "ON (II)" position.



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 try the update procedure
again.

2. Turn the ignition switch 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 ). If you are returning
from DLC circuit troubleshooting, skip step 4 to 8, then clean the throttle body after substituting the
PCM (see THROTTLE BODY CLEANING ).

4. USA, CANADA models: Select the INSPECTION MENU with the HDS.

5. USA, CANADA models: Select the ETCS TEST, then select the TP POSITION CHECK, and follow

the screen prompts.

6. Jump the SCS line with the HDS.

7. Remove the panels (A) (see step 5 under CENTER CONSOLE REMOVAL/INSTALLATION ),

and pull back the carpet.

8. Remove the duct (B).

9. Disconnect the PCM connectors (C).

NOTE:

USA, CANADA models: If the TP POSITION CHECK indicates FAILED,
continue this procedure.

10. Remove the bolts (D), then remove the PCM (E).

11. Install the parts in the reverse order of removal.

12. Open the SCS with the HDS.

13. Turn the ignition switch ON (II).

14. Manually input the VIN to the PCM with the HDS.

15. Update the PCM if it does not have the latest software.

16. Select the IMMOBI SYSTEM with the HDS.

17. Enter the immobilizer code with the PCM replacement procedure in the HDS; it allows you to start

the engine.

18. Reset the PCM with the HDS.

19. If the TP POSITION CHECK failed in step 5, clean the throttle body (see THROTTLE BODY

CLEANING ).

20. Do the PCM idle learn procedure (see PCM IDLE LEARN PROCEDURE ).

21. Do the CKP pattern learn procedure.

OBD STATUS

The OBD status shows the current system status of each DTC and all of the parameters. This function is
used to see if the repair was successfully completed. The results of diagnostic tests for the DTC are
displayed as:



PASSED: The on board diagnosis is successfully finished.



FAILED: The on board diagnosis has finished but failed.



EXECUTING: The vehicle is in enable criteria conditions for the DTC and the on board diagnosis is
running.



NOT COMPLETED: The on board diagnosis was running but is out of the enable conditions of the
DTC.



OUT OF CONDITION: The vehicle has stayed out of the enable conditions for the DTC.
