DIAGNOSIS PROCEDURE

Step	Check	Yes	No
1 CHECK CURRENT DATA. Start the engine. Read the data of tumble generator valve position sensor signal (RH) using Subaru Select Monitor or general scan tool. NOTE: Subaru Select Monitor For detailed operation procedure, refer to SUBARU SELECT MONITOR . General scan tool For detailed operation procedures, refer to the general scan tool operation manual.	Is the voltage 5 V or more?	Go to step 2.	Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, temporary poor contact of connector may be the cause.
2 CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ASSEMBLY RH CONNECTOR. Turn the ignition switch to OFF. Disconnect the connector from tumble generator valve assembly RH. Start the engine. Read the data of tumble generator valve position sensor signal (RH) using Subaru Select Monitor or general scan tool. NOTE: Subaru Select Monitor For detailed operation procedure, refer to SUBARU SELECT MONITOR . General scan tool For detailed operation procedures, refer to the general scan tool operation manual.	Is the voltage 5 V or more?	Repair the short circuit to power in harness between ECM and tumble generator valve assembly RH connector.	Go to step 3.
3 CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ASSEMBLY RH CONNECTOR. Turn the ignition switch to OFF. Measure the resistance of harness between tumble generator valve assembly RH connector and engine ground. Connector & terminal (E55) No. 2 - Engine ground:	Is the resistance less than 5 Ω?	Go to step 4.	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit in harness between ECM and tumble generator valve assembly RH connector Poor contact in ECM connector Poor contact of coupling connector
4 CHECK POOR CONTACT. Check for poor contact of tumble generator valve assembly RH connector.	Is there poor contact in the tumble generator valve assembly RH connector?	Repair the poor contact of tumble generator valve assembly RH connector.	Replace the tumble generator valve assembly RH. Refer to TUMBLE GENERATOR VALVE ASSEMBLY .
