1 - 15GENINFOFEATURESLean angle cut-off switchThe lean angle cut-off switch stops the supply of fuel to the engine in case the motorcycle overturns.When the motorcycle is in the normal state, the cut-off switch outputs a constant voltage of approxi-mately 1.0 V (low level). When the motorcycle tilts, the float in the switch tilts in proportion to the tiltof the motorcycle. However, the voltage output to the ECU remains unchanged at the low level.When the tilt of the motorcycle exceeds 65 degrees (according to the tilt of the float), the signal fromthe sensor increases to approximately 4.0 V (high level). When the ECU receives the high-level volt-age, it determines that the motorcycle has overturned, and stops the delivery of fuel to the engine byturning OFF the fuel injection system relay that powers the fuel pump and the injectors. Once thecut-off switch is tripped, the ECU maintains this state; therefore, even if the motorcycle has recov-ered its upright position, this state will not be canceled unless the main switch is turned OFF, andthen turned back ON.È Output voltageÉ High levelÊ Low levelË Cut-off switch tilt angleÌ Fuel injection system relay OFF
