How to Remove the ECM for Testing

If 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. Remove the passenger's dashboard lower cover, the right kick panel, and the glove box.




5. Remove the bolt. Cut the plastic cross brace in the glove box opening with diagonal cutters in the area shown, and discard it.




6. Remove the bolts and the glove box frame (A), then remove the connectors (B) and relay holder (C).




7. Disconnect the connectors from the ECM mounting bracket. Disconnect the ECM connectors (A) from the ECM (B).
8. Remove the nuts, then remove the ECM (B).
