2 CHECK HARNESS BETWEEN ECM AND DELIVERY (TEST) MODE FUSE. Turn the ignition switch to OFF. Disconnect the connector from ECM. Measure the resistance between ECM and chassis ground. Connector & terminal (B136) No. 34 - Chassis ground:	Is the resistance 1 MΩ or more?	Replace the ECM. Refer to ENGINE CONTROL MODULE (ECM) .	Repair the short circuit to ground in harness between ECM and delivery (test) mode fuse.
