ESU03840 "D.C.S." (Detonation Control System) indicator light This snowmobile is equipped with a system which is able to detect and control engine detonations in order to protect the engine from damage. The "D.C.S." indicator light 1 flashes to inform the rider that the detonation control system has been activated. If a detonation is detected by the knock sensor, the system automatically adjusts the ignition timing for optimal firing, and the "D.C.S." indicator light flashes. The system helps protect the engine from detonation damage while the light is flashing. (See page 5-10 for "D.C.S." indicator light flash pattern numbers 1 and 2.) NOTE: @ G G @ If the detonation level increases, the "D.C.S." indicator light flash pattern changes from pattern number 1 to pattern number 2. If excessive detonation levels continue, maximum engine speed is reduced to protect the engine. Engine performance will decline according to the detonation level. After detonation stops, the engine protection control is deactivated, and the "D.C.S." indicator light goes off. NOTE: @ G G @ If the carburetor settings are not appropriate for the operating conditions, detonations may occur. If the "D.C.S." indicator light flashes continuously, it is recommended to consult a Yamaha dealer.
