Scheme 254

Scheme 255

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 (see «DLC CIRCUIT TROUBLESHOOTING»(ref-336453-S21745645342009072700000) ). If the result of the DLC circuit troubleshooting is to replace the PCM, skip steps 4 through 7, 16 through 21, and 24 through 25, and do the following procedures after replacing the PCM: Replace the engine oil (see «ENGINE OIL LEVEL CHECK»(ref-336454-S06414270182009072700000) ) and the engine oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-336454-S25079735732009072700000) ). Replace the ATF (see «ATF REPLACEMENT»(ref-371294-S19152170302010090700000) ).
4. Select the PGM-FI system with the HDS.
5. Select the REPLACE PCM MENU, then select READ DATA, and follow the HDS 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.
6. Select the A/T system with the HDS.
7. Select the REPLACE TCM/PCM MENU, then select READ DATA, and follow the HDS prompts. NOTE: Doing this step copies (READS) the ATF 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. Remove the cover (D).
11. Disconnect PCM connectors A, B, and C. NOTE: PCM connectors A, B, and C embossed on them for identification.
12. Remove the bolts (E), then remove the PCM assembly (F).
13. Install the PCM in the reverse order of removal.
14. Turn the ignition switch to ON (II).
15. 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.
16. If the READ DATA (engine oil life) failed in step 5 Go to step 19 . Otherwise Go to step 17
17. Select the PGM-FI system with the HDS.
18. Select the REPLACE PCM MENU, then select WRITE DATA, and follow the HDS prompts. NOTE: If the WRITE DATA indicates FAILED, continue with this procedure.
19. If the READ DATA (ATF life) failed in step 7, go to step 22 . Otherwise go to step 20.
20. Select the A/T SYSTEM with the HDS.
21. Select the REPLACE TCM/PCM MENU, then select WRITE DATA, and follow the HDS prompts. NOTE: If the WRITE DATA indicates FAILED, continue with this procedure.
22. Select IMMOBI system with the HDS.
23. Enter the immobilizer PCM code that you got from the iN, and use the PCM replacement procedure in the IMMOBI MENU of the HDS; it allows you to start the engine.
24. If the READ DATA failed in step 5 or the WRITE DATA failed in step 18, replace the engine oil (see «ENGINE OIL LEVEL CHECK»(ref-336454-S06414270182009072700000) ) and the engine oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-336454-S25079735732009072700000) ), then Go to step 25.
25. If the READ DATA failed in step 7 or the WRITE DATA failed in step 21, replace the ATF (see «ATF REPLACEMENT»(ref-371294-S19152170302010090700000) ), then go to step 26.
26. Clean the throttle body (see «THROTTLE BODY CLEANING»(ref-336463-S24328405052009072700000) ).
27. Select the PGM-FI system with the HDS, and reset the PCM with the HDS.
28. Update the PCM if it does not have the latest software (see «PCM UPDATE»(ref-336453-S09500398002009072700000) ).
29. Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-336473-S09468920992009072700000) ).
30. Do the CKP pattern learn procedure (see «CKP PATTERN CLEAR/CKP PATTERN LEARN»(ref-336452-S03293821702009072700000) ).
