PCM Replacement

Special Tools Required

1. Honda diagnostic system (HDS) tablet tester
2. Honda interface module (HIM) and an i N workstation with the latest HDS software version
3. HDS pocket tester
4. GNA600 and an i N workstation with the latest HDS software version

Any one of the above updating tools can be used.

Note. Make sure the HDS is loaded with the latest software version. If you are replacing the PCM after substituting a known-good PCM, reinstall the original PCM, then do this procedure. During the procedure, is any READ DATA, WRITE DATA, or other data checks fail, note the failure, then continue.

Scheme 538

Scheme 539

Scheme 540

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).
3. Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, go to the «DLC CIRCUIT TROUBLESHOOTING»(ref-351658-S38235661612009122700000) . If you are returning from DLC circuit troubleshooting, skip steps 4 through 7 , 20 through 25 , and do this after replacing the PCM: Replace the engine oil (see «ENGINE OIL REPLACEMENT»(ref-295005-S27768564692008081400000) ) and the engine oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-295005-S15978256812008081400000) ). Clean the throttle body (see «AIR CLEANER REMOVAL/INSTALLATION»(ref-295016-S17870361772008081400000) ).
4. Select the PGM-FI system with the HDS.
5. Select the INSPECTION MENU with the HDS.
6. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the screen prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue with this procedure.
7. Select the REPLACE PCM MENU, then select READ DATA and follow the screen prompts. NOTE: Doing this step copies (READS) the engine oil life data from the original PCM so you can later download (WRITES) it into the new PCM. If READ DATA indicates FAILED, continue with this procedure.
8. Turn the ignition switch to LOCK (0).
9. Jump the SCS line with the HDS.
10. Do the battery removal procedure (see «BATTERY REMOVAL AND INSTALLATION»(ref-295021-S34386589982009101400000) ).
11. Remove the cover (A).
12. Remove the bolts (D), then remove the PCM (E).
13. Disconnect PCM connectors A, B, and C. NOTE: PCM connectors A, B, and C have symbols (A=[], B=delta, C=o) embossed on them for identification.
14. Install the parts in the reverse order of removal.
15. Do the battery installation procedure (see «BATTERY REMOVAL AND INSTALLATION»(ref-295021-S34386589982009101400000) ).
16. Turn the ignition switch to ON (II).
17. Manually input the VIN to the PCM with the HDS. 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.
18. If the READ DATA (engine oil life) failed in step 7 , go to step 23 . Otherwise, go to step 19.
19. Select the PGM-FI system with the HDS.
20. Select the REPLACE PCM MENU, then select WRITE DATA and follow the screen prompts. NOTE: If the WRITE DATA indicates FAILED, continue with this procedure.
21. Select IMMOBI system with the HDS.
22. Enter the immobilizer code that you got from the i N, and use the PCM replacement procedure in the HDS; it allows you to start the engine.
23. If the TP POSITION CHECK failed in step 6 clean the throttle body (see «AIR CLEANER REMOVAL/INSTALLATION»(ref-295016-S17870361772008081400000) ), then go to step 24.
24. If the READ DATA failed in step 8 or the WRITE DATA failed in step 20 , replace the engine oil (see «ENGINE OIL REPLACEMENT»(ref-295005-S27768564692008081400000) ) and engine oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-295005-S15978256812008081400000) ), then go to step 25.
25. Select PGM-FI system and reset the PCM with the HDS.
26. Update the PCM if it does not have the latest software (see «PCM UPDATE»(ref-351658-S06327977152009122700000) ).
27. Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-295027-S32794534722008081400000) ).
28. Do the CKP pattern learn procedure (see «CRANK (CKP) PATTERN CLEAR/CRANK (CKP) PATTERN LEARN»(ref-295024-S29291448842008081400000) ).
