Pilot 4WD V6-3.5L (2008)
10. Remove the mounting bolts (E), then remove the PCM (F).
11. Install the PCM in the reverse order of removal.
12. Open the SCS with the HDS.
13. Turn the ignition switch ON (II).
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.
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 using the PCM replacement procedure in the HDS; this 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.
20. Do the PCM idle learn procedure.
21. Do the crank (CKP) pattern learn procedure.
Updating the PCM
Updating 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
^
GNA600 and an iN workstation with HDS and CM update software
NOTE:
^
Use this procedure when you have to update the PCM during troubleshooting procedure.
^
Make sure the HDS/HIM has the latest software version downloaded from the iN (interactive network).
^
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 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, moonroof (if equipped), 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 an 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 has been 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 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.
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. If it do not, go to the DLC circuit troubleshooting. If you are returning from the DLC circuit
troubleshooting, skip steps 4 to 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: If the TP POSITION CHECK indicates FAILED, continue this procedure.
