How to Remove the ECM for TestingIf the troubleshooting for a code requires voltage or resistance checks at the ECM connectors, remove the ECM and test it:
1. Turn the ignition switch OFF.
2. Wait for 1 minute. If the radiator fan is running, wait for 1 minute after the radiator fan stops.
3. Disconnect the negative cable from the battery.
4. Pull the passenger's side carpet back to expose the ECM (A).
5. Unbolt the ECM cover (B).
6. Lift the lower edge of the ECM cover off of the lower studs. Make sure the ECM is not touching the studs.
7. Lift the upper edge of the ECM cover enough to clear the upper studs, then pull the cover down away from the evaporator drain tube.
8. Unbolt the ECM from the cover.
9. Disconnect the ECM connectors.
10. Install the ECM in the reverse order of removal.
11. Turn the ignition switch ON (II).
NOTE: For 2005 model: DTC P0630 "VIN Not Programmed or Mismatch" will be stored because VIN has not been programmed into the ECM, but ignore it and continue this procedure.
12. For 2005 model: Input: the VIN to the ECM with the HDS.
13. Rewrite the immobilizer code with the ECM replacement procedure in the HDS; it allows you to start the engine.
14. Do the ECM idle learn procedure.
15. Remove the No.15 (40 A) fuse from the under-hood fuse-relay box.
16. If the IMA battery level gauge (BAT) displays no segments, start the engine, and hold it between 3,500 rpm and 4,000 rpm without load (in Park or neutral) until the BAT displays at least three segments.
17. Reinstall the No.15 (40 A) fuse.
