OPERATION
l
If the operator turns the muffler mode changeover switch to ON or OFF position, this is converted
to high/low voltage to be sent to the engine control module. Receiving this signal, the engine control
module performs the dual mode (TOUR/SPORT mode) muffler control.
l
The output terminal of the muffler mode changeover switch has battery voltage applied to it from
the engine control module through the resistor inside the module. Place the muffler mode changeover
switch to the ON position, and the muffler mode changeover switch circuit will be closed to short
the voltage applied to output terminal to the ground. Accordingly, the output voltage of the muffler
mode changeover switch changes from high to low.
