DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK HARNESS BETWEEN ECM AND ELECTRONIC THROTTLE CONTROL CONNECTOR. Turn the ignition switch to OFF. Disconnect the connectors from ECM and electronic throttle control. Measure the resistance between ECM connector and chassis ground. Connector & terminal (B134) No. 19 - Chassis ground: (B134) No. 28 - Chassis ground:	Is the resistance 1 MΩ or more?	Go to step 2 .	Repair the ground short circuit of harness between ECM connector and electronic throttle control connector.
2 CHECK SHORT CIRCUIT INSIDE THE ECM. Connect the connector to ECM. Measure the resistance between electronic throttle control connector and engine ground. Connector & terminal (E57) No. 4 - Engine ground:	Is the resistance 1 MΩ or more?	Replace the electronic throttle control. <Ref. to THROTTLE BODY .>	Repair the ground short circuit of harness between ECM connector and electronic throttle control connector. Replace the ECM if defective. <Ref. to ENGINE CONTROL MODULE (ECM) .>
