How to Substitute the PCM

How to Substitute the PCM





1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
2. Make sure the HDS communicates with the PCM. If it doesn't, skip steps 3 to 5 and clean the throttle body after this procedure.
3. Turn the ignition switch ON (II).
4. Select the INSPECTION MENU with the HDS.
5. Do the TP POSITION CHECK in the ETCS TEST.
6. Turn the ignition switch OFF.
7. Jump the SCS line with the HDS.





8. Remove the center lower covers (A).
9. Remove the duct (B).
10. Disconnect PCM connectors (C).
11. Remove the bolts (D), then remove the PCM (E).
12. Install the PCM in the reverse order of removal.
13. Open the SCS line with the HDS.
14. Turn the ignition switch ON (II).

NOTE: DTC P0630 "VIN Not Programmed or Mismatch" may be stored because 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. Rewrite 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. Do the PCM idle learn procedure.
19. Do the CKP pattern clear/pattern learn procedure with the HDS.
