Inspection Procedure

INSPECTION

Connectors of the Engine Control Module are water-proof and are the bolt type. For water proof type connectors, in order to measure the voltage of Engine Control Module terminals and the resistance of connected parts, connect the inspection sub wire harness between the Engine Control Module and vehicle wire harness, then perform the inspection. The inspection method of inserting a tester probe from the other side of connector noticeably reduces the water-proof ability. Disconnect the connector by fully loosening the bolt.

Preparation

1. Turn the Ignition Switch to LOCK position.
2. Turn up the passenger side floor mat.
3. Remove the Engine Control Module protector.
4. Disconnect the connector from the Engine Control Module. After completely loosening the bolt, the 2 parts of the connector can be separated.

NOTE: Do not pull the wire harness when disconnecting the connector. When disconnecting the connector, the Engine Control Module back-up power source is cut off, so the malfunction codes, etc. recorded in the Engine Control Module memory are cancelled. 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 Engine Control Module and connector of vehicle wire harness (SST 09990-01000).
6. Perform standard voltage test of each Engine Control Module terminal and verify readings.








NOTE: The arrangement of the check connector terminals are the same as those of the Engine Control Module.

7. After performing test, disconnect the Check Harness A.
8. Reconnect the connector to the Engine Control Module.
- Match the male connector correctly with the female connector, then press them together.





- Tighten the bolt





- Make sure the connector is completely connected, by tightening the bolt until there is a clearance of less than 1 mm (0.04 in) between bottom of the male connector and end of the female connector.

9. Install the Engine Control Module protector and floor mat.
