Connector & terminal (B134) No. 23 (+) - Chassis ground (-): (B134) No. 24 (+) - Chassis ground (-):	Is the voltage 5 V or more?	Repair the short circuit to power in harness between ECM and tumble generator valve actuator LH connector.	Replace the tumble generator valve actuator LH. Refer to TUMBLE GENERATOR VALVE ACTUATOR .
