2007 Honda Accord V6-3.0L HybridSECTION How to Substitute the PCM
Substituting the PCM
Special Tools Required
^ Honda diagnostic system (HDS)
^ Honda interface module (HIM)
^ HDS pocket tester These special tools are available through the Honda tool and Equipment Program.
Use this procedure when you need to substitute a known-good PCM during troubleshooting procedures.
NOTE: To ensure the latest program is installed, do a PCM update whenever the PCM is substituted.
1. Turn the ignition switch ON (II).
2. Connect the HDS to the (DLC) located under the steering column lower cover.
3. Make sure the HDS communicates with the PCM. If it does 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 substituting 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.

9. Remove the duct (B).
10. Disconnect the PCM connectors (C).
11. Remove the bolts (D), then remove the PCM (E).
12. Install a known-good PCM and removed parts in the reverse order of removal.
13. Open the SCS with the HDS.
14. Turn the ignition switch ON (II).
NOTE: If 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.
15. Input the VIN to the PCM with the HDS.
16. Update the PCM if it does not have the latest software.
17. Select the IMMOBILIZER SYSTEM with the HDS.
18. Enter the immobilizer code with the PCM replacement procedure in the HDS; it allows you to start the engine.
19. Reset the PCM with the HDS.
20. If the TP POSITION CHECK failed in step 5, clean the throttle body.
21. Do the PCM idle learn procedure.
22. Do the CKP pattern learn procedure.
