Does the malfunction indicator light illuminate?	Repair the ground short circuit of harness between ECM and combination meter connector.	Go to step 3 .
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. Ref. to ENGINE CONTROL MODULE (ECM) .
