DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK HARNESS BETWEEN STARTER RELAY (PUSH BUTTON START) CONNECTOR AND STARTER CUT RELAY CONNECTOR. Turn the ignition to OFF. Remove the starter relay (push button start) and starter cut relay. Measure the resistance of harness between starter relay (push button start) connector and starter cut relay connector. Connector & terminal (B225) No. 28 - (B225) No. 42:	Is the resistance less than 1 Ω?	Go to step 2.	Repair the open circuit in harness between starter relay (push button start) connector and starter cut relay connector.
2 CHECK HARNESS BETWEEN ECM AND STARTER CUT RELAY CONNECTOR. Disconnect the connector from ECM. Measure the resistance of harness between ECM connector and starter cut relay connector. Connector & terminal (B135) No. 34 - (B225) No. 40:	Is the resistance less than 1 Ω?	Go to step 3.	Repair the open circuit of harness between ECM connector and starter cut relay connector.
3 CHECK STARTER CUT RELAY. Connect the battery to starter cut relay terminals No. 40 and No. 42. Measure the resistance between starter cut relay terminals. Terminals No. 41 - No. 44:	Is the resistance 1 MΩ or more?	Repair the poor contact of ECM connector.	Replace the starter cut relay. < Ref. to STARTER CUT RELAY . >
