Check Engine Light Switch-Off Key - Mivv Compatible With Yamaha Mt-09 - Sp (2025-2026)

Plug-and-play electronic onboard diagnostic (OBD) device for Euro 5+ motorcycles, designed to prevent the Check Engine warning light from illuminating when the original catalytic converter has been replaced with an aftermarket unit that may generate oxygen sensor readings different from those expected by the vehicle's factory calibration. The solution helps avoid unwanted warning indications while maintaining the functionality of the onboard diagnostic (OBD) system. It does not modify the engine control unit (ECU) software, alter engine management maps, or affect any other electronic systems of the vehicle.
