have the latest software (see page 11-227), or
substitute a known-good ECM/PCM (see page 11-7),
then recheck. If the symptom/indication goes away
with a known-good ECM/PCM, replace the original
ECM/PCM (see page 11-228). Also replace the

3. Make sure the HDS communicates with the ECM/ PCM and other vehicle systems. If it doesn’t, go to
the DLC circuit troubleshooting (see page 11-204). If
you are returning from DLC circuit troubleshooting,
skip steps 4 through 9, 20 through 25, and 28
through 30, and do these procedures after
replacing the ECM/PCM;
 Replace the engine oil (see page 8-10) and the engine oil filter (see page 8-11).
 Replace the ATF (A/T model) (see page 14-232).
 Clean the throttle body (see page 11- 344).
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 ECM/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 ECM/PCM so you can later
download (WRITES) it into the new ECM/PCM.
 If READ DATA indicates FAILED, continue with this procedure.
8. A/T model: Select the A/T system with the HDS.
9. A/T model: Select the REPLACE TCM/PCM MENU, then select READ DATA and follow the screen
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. 10. Turn the ignition switch to LOCK (0).
11. Jump the SCS line with the HDS.
12. Do the battery removal procedure (see page 22-69).
13. Remove the cover (A).
14. Remove the bolts (D), then remove the ECM/PCM
(E).
15. Disconnect ECM/PCM connectors A, B, and C. NOTE: ECM/PCM connectors A, B, and C have
symbols (A= , B= , C= ) embossed on them for
identification.

16. Install the parts in the reverse order of removal.
17. Do the battery installation procedure (see page
22-69).
18. Turn the ignition switch to ON (II).
19. Manually input the VIN to the ECM/PCM with the HDS.
NOTE: DTC P0630 VIN Not Programmed or
Mismatch may be stored because the VIN has not
been programmed into the ECM/PCM; ignore it,
and continue this procedure.
20. If the READ DATA (engine oil life) failed in step 7, go to step 23 (A/T) or step 26 (M/T). Otherwise, go
to step 21.
21. Select the PGM-FI system with the HDS.
22. Select the REPLACE ECM/PCM MENU, then select WRITE DATA, and follow the screen prompts.
NOTE: If the WRITE DATA indicates FAILED,
continue with this procedure.
23. A/T model: If the READ DATA (ATF life) failed in step 9, go to step 26. Otherwise go to step 24.
24. A/T model: Select the A/T SYSTEM with the HDS.
25. A/T model: Select the REPLACE TCM/PCM MENU, then select WRITE DATA, and follow the screen
prompts.
NOTE: If the WRITE DATA indicates FAILED,
continue with this procedure.
26. Select IMMOBI system with the HDS.
27. Enter the immobilizer code that you got from the iN or use the ECM/PCM replacement procedure in the
HDS; it allows you to start the engine.
28. If the TP POSITION CHECK failed in step 7, clean the throttle body (see page 11- 344), then go to step
29. 29. IftheREADDATAfailedinstep8ortheWRITE
DATA failed in step 22, replace the engine oil
(see page 8-10) and engine oil filter (see page 8-11),
then go to step 30 (A/T) or step 31 (M/T).
30. If the READ DATA failed in step 10 or the WRITE DATA failed in step 27, replace the ATF (see page
14-232), then go to step 31.
31. Select PGM-FI system, and reset the ECM/PCM with the HDS.
32. Update the ECM/PCM if it does not have the latest software (see page 11-227).
