DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK HARNESS BETWEEN ECM AND STARTER RELAY CONNECTOR . Turn the ignition to OFF. Disconnect the connector from ECM. Remove the starter relay. Measure the resistance of harness between ECM connector and starter relay connector. NOTE: For CVT model, place the select lever in "P" range or "N" range. Connector & terminal (B134) No. 8 - (B225) No. 1:	Is the resistance less than 1 Ω?	Go to step 2 .	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit of harness between ECM connector and starter relay connector Poor contact of coupling connector
2 CHECK HARNESS BETWEEN ECM AND STARTER RELAY CONNECTOR . Disconnect the connector from starter motor. Measure the resistance between the ECM connector and engine ground. Connector & terminal (B134) No. 8 - Engine ground:	Is the resistance 1 MΩ or more?	Repair the poor contact of ECM connector.	Repair the short circuit to ground in harness between ECM connector and starter relay connector.
