Main Line Between TCM and Data Link ConnectorNKS004NY
INSPECTION PROCEDURE
1. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Disconnect the connector of ECM and the harness connector M82 and F102.
4. Check the continuity between the harness connector and the data link connector.
