7. If the software in the ECM/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 ECM/PCM is not the latest, follow
the instructions on the screen. If prompted to
choose the PGM-FI system or the A/T system (A/T),
make sure you update both.
NOTE: If the ECM/PCM update system requires you
to cool the ECM/PCM, follow the instructions on the
screen. If you have a problem during the update
(programming takes over 15 minutes, status bar
goes over 100 %, D (A/T) or immobilizer indicator
flashes, HDS tablet freezes, etc.), follow these steps
to minimize the chance of damaging the ECM/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 page 11- 344).
9. Do the ECM/PCM idle learn procedure (see page 11-310).
10. Do the CKP pattern clear/CKP pattern learn procedure (see page 11-4).  Honda diagnostic system (HDS) tablet tester
 Honda interface module (HIM) and an iN workstation
with the latest HDS software version
 HDS pocket tester
 GNA 600 and an iN workstation with the latest HDS software version
Any one of the above updating tools can be used.
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).

18. Turn the ignition switch to ON (II).
19. 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.
20. If the READ DATA (engine oil life) failed in step 7, go to step 23 (A/T) or step 26 (M/T). Otherwise, go
to step 21.
21. Select the PGM-FI system with the HDS.
22. Select the REPLACE ECM/PCM MENU, then select WRITE DATA, and follow the screen prompts.

24. A/T model: Select the A/T SYSTEM with the HDS.
25. A/T model: Select the REPLACE TCM/PCM MENU, then select WRITE DATA, and follow the screen
prompts.
NOTE: If the WRITE DATA indicates FAILED,
continue with this procedure.
26. Select IMMOBI system with the HDS.
27. Enter the immobilizer code that you got from the iN or use the ECM/PCM replacement procedure in the
HDS; it allows you to start the engine.
28. If the TP POSITION CHECK failed in step 7, clean the throttle body (see page 11- 344), then go to step
29. 29. IftheREADDATAfailedinstep8ortheWRITE

(see page 8-10) and engine oil filter (see page 8-11),
then go to step 30 (A/T) or step 31 (M/T).
30. If the READ DATA failed in step 10 or the WRITE DATA failed in step 27, replace the ATF (see page
14-232), then go to step 31.
31. Select PGM-FI system, and reset the ECM/PCM with the HDS.
32. Update the ECM/PCM if it does not have the latest software (see page 11-227).
