1.CHECK HARNESS BETWEEN ECM AND STARTER RELAY CONNECTOR.
1) Turn the ignition to OFF.
2) Disconnect the connectors from ECM.
3) Remove the starter relay.
4) Measure the resistance of harness between ECM and starter relay connector.
NOTE:
For AT model, place the select lever in “P” range or “N” range.

Repair the harness and connector.
NOTE:
In this case, repair the following item:
• Open circuit of harness between ECM and starter relay connector
• Poor contact of coupling connector
