Step	Check	Yes	No
1 CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ASSEMBLY LH CONNECTOR. Turn the ignition switch to OFF. Disconnect the connector from ECM. Disconnect the connector from tumble generator valve assembly LH. Measure the resistance of harness between ECM connector and tumble generator valve assembly LH connector. Connector & terminal (E158) No. 39 - (E51) No. 5: (E158) No. 26 - (E51) No. 4:	Is the resistance less than 1 Ω?	Go to step 2	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit in harness between ECM connector and tumble generator valve assembly LH connector Poor contact of coupling connector
2 CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ASSEMBLY LH CONNECTOR. Measure the resistance between ECM connector and chassis ground. Connector & terminal (E158) No. 39 - Chassis ground: (E158) No. 26 - Chassis ground:	Is the resistance 1 MΩ or more?	Go to step 3	Repair the short circuit to ground in harness between ECM connector and tumble generator valve assembly LH connector.
3 CHECK FOR POOR CONTACT. Check for poor contact of tumble generator valve assembly LH connector.	Is there poor contact of the tumble generator valve assembly LH connector?	Repair the poor contact of tumble generator valve assembly LH connector.	Replace the tumble generator valve assembly LH. Ref. to TUMBLE GENERATOR VALVE
