ECM/PCM Replacement

NOTE: If the troubleshooting leads to replace the ECM/PCM after substituting a known-good ECM/PCM, reinstall the original ECM/PCM first, then do this procedure.

1.Make sure you have the anti-theft code for the audio.

2.Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.


3.Remove the battery.

4.Remove the cover (A).


5.Remove the bolts (A), then remove the ECM/PCM (B).


6.Disconnect the ECM/PCM connectors A (C), B (D), and C (E).

NOTE: ECM/PCM connectors A, B, and C have symbols (A=¨, B=[utri], C=¡) embossed on them for identification.

7.Install the ECM/PCM and battery in the reverse order of removal.

8.KE, KG, TR models: 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 ECM/PCM; ignore it, and continue this procedure.

9.KE, KG, TR models: Input the VIN to the ECM/PCM with the HDS.

10.Rewrite the immobilizer code with the ECM/PCM replacement procedure in the HDS; it allows you to start the engine.

11.Reset the ECM/PCM with the HDS.

12.Do the ECM/PCM idle learn procedure.

13.Do the crank pattern learn procedure.

14.Enter the anti-theft code for the audio and set the clock.
