Measure the voltage between ECM connector and chassis ground. Connector & terminal (E158) No. 13 (+) - Chassis ground (-): (E158) No. 52 (+) - Chassis ground (-):	Is the voltage 5 V or more?	Repair the short circuit to power in harness between ECM connector and tumble generator valve actuator RH connector.
