Suzuki GSX-R 1000 Service Manual: Exhaust control system operation
The excs is operated by the signal supplied from the ecm. The open/close operation of the excv is performed by the excva which is controlled by the ecm by changing the current direction of the actuator motor. The position sensor (incorporated in the excva) detects the excva movement by measuring the voltage and then the ecm determines the excv opening angle based on the engine rpm and gear positions. Every time the ignition switch is turned on, the excva automatically drives the excv and detects full close/open position voltages and sets the excv to middle position.
