DIAGNOSTIC PROCEDURE (DTC P2008)

Step		Check	Yes	No
1 CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR CONNECTOR. Turn the ignition switch to OFF. Disconnect the connector from tumble generator valve and ECM connector. Measure the resistance between tumble generator valve actuator and ECM connector. Connector & terminal (E62) No. 1 - (B134) No. 9: (E62) No. 2 - (B134) No. 8:		Is the resistance less than 1 ?	Go to step 2.	Repair the open circuit between ECM and tumble generator valve connector. NOTE: In this case, repair the following: Open circuit in harness between ECM and tumble generator valve actuator connector. Poor contact in coupling connector.
2 CHECK POOR CONTACT. Check poor contact in tumble generator valve actuator connector.		Is there poor contact in tumble generator valve actuator connector?	Repair the poor contact in tumble generator valve actuator connector.	Replace the tumble generator valve actuator. < Ref. to TUMBLE GENERATOR VALVE ACTUATOR . >
