3 CHECK HARNESS BETWEEN ECM AND DELIVERY (TEST) MODE FUSE. Turn the ignition switch to OFF. Install the delivery (test) mode fuse of the main fuse box. Measure the resistance of harness between ECM connectors. Connector & terminal (B136) No. 4 - (B136) No. 34	Is the resistance less than 1 Ω?	Go to step 4 .	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit of harness between ECM and delivery (test) mode fuse Poor contact of joint connector
4 CHECK FOR POOR CONTACT. Check for poor contact of ECM connector.	Is there poor contact of ECM connector?	Repair the poor contact of ECM connector.	Replace the ECM. Refer to ENGINE CONTROL MODULE (ECM) Engine Control Module (ECM).
