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 procedures, refer to "READ CURRENT DATA FOR ENGINE". Refer to , SUBARU SELECT MONITOR . General scan tool For detailed operation procedures, refer to the general scan tool operation manual.	Is the voltage less than 0.2 V?	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, temporary open or short circuit of harness may be the cause.
2 CHECK POWER SUPPLY OF TUMBLE GENERATOR VALVE ASSEMBLY RH. Turn the ignition switch to OFF. Disconnect the connector from tumble generator valve assembly RH. Turn the ignition switch to ON. Measure the voltage between tumble generator valve assembly RH connector and engine ground. Connector & terminal (E55) No. 3 (+) - Engine ground (-):	Is the voltage 4.5 V or more?	Go to step 3 .	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 of ECM connector Poor contact of coupling connector
3 CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ASSEMBLY RH CONNECTOR. Turn the ignition switch to OFF. Disconnect the connector from ECM. Measure the resistance of harness between ECM and tumble generator valve assembly RH. Connector & terminal (B137) No. 11 - (E55) No. 1:	Is the resistance less than 1 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 of coupling connector
4 CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ASSEMBLY RH CONNECTOR. Measure the resistance between ECM and chassis ground. Connector & terminal (B137) No. 11 - Chassis ground:	Is the resistance 1 MΩ or more?	Go to step 5 .	Repair the short circuit to ground in harness between ECM and tumble generator valve assembly RH connector.
5 CHECK FOR POOR CONTACT. Check for poor contact of tumble generator valve assembly RH connector.	Is there poor contact of ECM or the tumble generator valve assembly RH connector?	Repair the poor contact of ECM or tumble generator valve assembly RH connector.	Replace the tumble generator valve assembly RH. Refer to FU(H4DOTC)-47, Tumble Generator Valve Assembly.
