DIAGNOSIS PROCEDURE

Step	Check	Yes	No
1 CHECK ELECTRONIC THROTTLE CONTROL RELAY. Turn the ignition switch to OFF. Remove the electronic throttle control relay. Measure the resistance between electronic throttle control relay terminals. Terminals No. 8 - No. 7:	Is the resistance more than 1 MΩ?	Go to step 2.	Replace the electronic throttle control relay.
2 CHECK SHORT CIRCUIT OF ELECTRONIC THROTTLE CONTROL RELAY POWER SUPPLY. Turn the ignition switch to ON. Measure the voltage between electronic throttle control relay connector and chassis ground. Connector & terminal (B362) No. 7 (+) - Chassis ground (-):	Is the voltage more than 5 V?	Go to step 3.	Repair the power supply short circuit of harness between ECM and electronic throttle control relay.
3 CHECK HARNESS BETWEEN ECM AND ELECTRONIC THROTTLE CONTROL RELAY. Turn the ignition switch to OFF. Disconnect the connectors from ECM. Measure the resistance between ECM connector and engine ground. Connector & terminal (B136) No. 21 - Engine ground:	Is the resistance more than 1 MΩ?	Repair the poor contact of ECM connector. Replace the ECM if defective. < Ref. to ENGINE CONTROL MODULE (ECM) . >	Repair the ground short circuit of harness between ECM and electronic throttle control relay.
