Step	Check	Yes	No
1 CHECK STATUS OF MALFUNCTION INDICATOR LIGHT. Turn the ignition switch to OFF. Check the delivery (test) mode fuse is removed. Turn the ignition switch to ON. (engine OFF)	Does the malfunction indicator light illuminate?	Go to step 2 .	Repair the malfunction indicator light circuit. Refer to MALFUNCTION INDICATOR LIGHT DOES NOT COME ON .
2 CHECK VEHICLE SPECIFICATION.	Is the vehicle except for C6 model?	Go to step 4 .	Go to step 3 .
3 CHECK HARNESS BETWEEN ECM AND COMBINATION METER CONNECTOR. Turn the ignition switch to OFF. Disconnect the connector from ECM. Turn the ignition switch to ON.	Does the malfunction indicator light illuminate?	Repair the ground short circuit of harness between ECM and combination meter connector.	Go to step 4 .
4 CHECK HARNESS BETWEEN ECM AND DELIVERY (TEST) MODE FUSE. Turn the ignition switch to OFF. Disconnect the connector from ECM. Install the delivery (test) mode fuse. CAUTION: Do not use any fuses that are installed on the vehicle. Measure the resistance of harness between ECM connectors. Connector & terminal (B136) No. 34 - (B136) No. 4:	Is the resistance less than 1 Ω?	Go to step 5 .	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
5 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) .
