ECM Terminal Inspection

1. Turn the ignition switch to LOCK position.
2. Turn up the passenger side floor mat.
3. Remove the ECM protector.
4. Disconnect the connectors from the ECM.
- After completely loosening the bolt, the 2 parts of connector can be separated.

NOTICE:
- Do not pull the wire harness when disconnecting the connector.
- When disconnecting the connector, the ECM's backup power source is cut off, so the DTCs, etc. recorded in the ECM memory are canceled.
- Never insert a tester probe or male terminal used for inspection purposes into the female terminal of the vehicle wire harness. Otherwise, the female terminal may be widened, which can result in faulty connection.





5. Connect the Check Harness A between ECM and connector of vehicle wire harness. SST 09990-01000

HINT: The arrangement of the DLC1 terminals are the same as those of the ECM.
