Substituting the PCM

Special Tools Required

Fuel and Emissions Systems

General Troubleshooting Information (cont’d)

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.

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.

8. If the TP POSITION CHECK failed in step 6, clean

the throttle body (see page 11-314).

9. Do the PCM idle learn procedure (see page 11-273).

10. Do the crank (CKP) pattern learn procedure.

• 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

NOTE: 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.

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 page 11-194). If
you are returning from DLC circuit troubleshooting,
skip step 4 to 8, then clean the throttle body after
substituting the PCM (see page 11-314).

4. Select the INSPECTION MENU with the HDS.

5. Select the ETCS TEST, then select the TP POSITION

CHECK, and follow the screen prompts.

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

6. Jump the SCS line with the HDS.

7. Remove the cover (D).

8. Disconnect PCM connectors A, B, and C.

NOTE: PCM connectors A, B, and C have symbols
(A=

, B=

, C=

) embosed on them for

identification.

9. Remove the bolts (E), then remove the PCM (F).

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

11. Open the SCS with the HDS.

12. 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.

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

14. Update the PCM if it does not have the latest

software.

15. Select the IMMOBI SYSTEM with the HDS.

16. Enter the immobilizer code with the PCM

replacement procedure in the HDS; it allows you to
start the engine.

17. Reset the PCM with the HDS.

18. If the TP POSITION CHECK failed in step 6, clean

the throttle body (see page 11-314).

19. Do the PCM idle learn procedure (see page 11-273).

20. Do the crank (CKP) pattern learn procedure.

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.
