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: Place the select lever in "P" range or "N" range. Connector & terminal (B134) No. 58 - (B159) No. 4:	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 ECM connector and chassis ground. Connector & terminal (B134) No. 58 - Chassis 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.
