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.

Use of sds
Ecm stores the engine and driving conditions (in the form of data as shown in
the figure) at the moment of the
detection of a malfunction in its memory. This data is called “show data when
trouble”.
Therefore, it is possible to know engine and driving conditions (e.G., Whether

Ecm / various sensors
Since each component is a high-precision part, great
care should be taken not to apply any severe impacts
during removal and installation.
Be careful not to touch the electrical terminals of the
electronic parts (ecm, etc.). The static electricity from
your body may damage them. ...
