  • Page 11: Features

    FEATURES EAS20170 FEATURES ET2C01025 OUTLINE OF THE FI SYSTEM The main function of a fuel supply system is to provide fuel to the combustion chamber at the optimum air-fuel ratio in accordance with the engine operating conditions and the atmospheric temperature. In the conventional carburetor system, the air-fuel ratio of the mixture that is supplied to the combustion chamber is created by the volume of the intake air and the fuel that is metered by the jet used in the respective carburetor.

  • Page 12: Fi System

    FEATURES ET3P61042 FI SYSTEM The fuel pump delivers fuel to the fuel injector via the fuel filter. The pressure regulator maintains the fuel pressure that is applied to the fuel injector at only 324 kPa (3.24 kg/cm², 47.0 psi). Accordingly, when the energizing signal from the ECU energizes the fuel injector, the fuel passage opens, causing the fuel to be injected into the intake manifold only during the time the passage remains open.

  • Page 13: Ycc-T (Yamaha Chip Controlled Throttle)

    Yamaha developed the YCC-T system employing the most advanced electronic control technologies. Electronic control throttle systems have been used on automobiles, but Yamaha has developed a fast- er, more compact system specifically for the needs of a sports motorcycle. The Yamaha-developed system has a high-speed calculating capacity that produces computations of running conditions every 1/1000th of a second.

  • Page 15: Outline Of The Cruise Control System

    FEATURES EAS1MC1087 OUTLINE OF THE CRUISE CONTROL SYSTEM This model is equipped with a cruise control system designed to maintain a set cruising speed. Be- cause the vehicle is equipped with the YCC-T system, the cruise control system can be controlled elec- tronically.
  • Page 16 FEATURES EWA1MC1006 WARNING • Improper use of the cruise control system may result in loss of control, which could lead to an accident. Do not activate the cruise control system in heavy traffic, poor weather conditions, or among winding, slippery, hilly, rough or gravel roads. •...

  • Page 19 Because the automatic deactivation of the cruise control system is stored in the memory of the ECU, the deactivation can be checked using the Yamaha diagnostic tool. In some cases, the cruise control system may not be able to maintain the set cruising speed when the vehicle is traveling uphill or downhill.

  • Page 21 FEATURES • If the cruise control system turned off because a malfunction was detected by the FI self-diagnosis, the cruise control power switch “ ” must be pushed once before the system can return to the normal operating condition. • If a switch for the cruise control system is malfunctioning (fault code No. 90 and 91), the engine trouble warning light will not come on because the normal operation of the vehicle is not affected.

  • Page 22: Outline Of The Unified Brake System

    OUTLINE OF THE UNIFIED BRAKE SYSTEM The Yamaha unified brake system is a system that operates one set of pistons in the front brakes to- gether with the rear brake when the brake pedal is depressed. Compared to conventional brake sys- tems, the ability to slow the vehicle using the simple operation of the brake pedal is improved.
  • Page 23 FEATURES Brake pedal input force and braking force at each wheel a. Brake force e. Proportioning valve operation b. Brake pedal force f. Metering valve operation c. Rear brake force d. Front brake force (unified brake system) Metering valve This valve prevents the brake fluid pressure that is transmitted to the right front brake caliper from in- creasing until the pressure exceeds a set level.

  • Page 24: Outline Of The Abs

    8. Rear wheel sensor The operation of the Yamaha ABS brakes is the same as conventional brakes on other vehicles, with a brake lever for operating the front brake and a brake pedal for operating the rear brake. However, part of the front brake is operated together with rear brake.
  • Page 25 FEATURES When the brakes are applied, wheel speed and chassis speed are reduced. However, the chassis travels forward by its inertia even though the wheel speed is reduced. • Brake force: The force applied by braking to reduce the wheel speed. •...
  • Page 26 FEATURES Wheel slip and hydraulic control The ABS ECU calculates the wheel speed of each wheel according to the rotation signal received from the front and rear wheel sensors. In addition, the ABS ECU calculates the vehicle chassis speed and the rate of speed reduction based on the wheel speed values.
  • Page 27 Slip ratio (%) b. Brake force Electronic ABS features The Yamaha ABS (anti-lock brake system) has been developed with the most advanced electronic technology. The ABS control is processed with good response under various vehicle travel conditions. The ABS also includes a highly developed self-diagnosis function. The ABS detects any problem con- dition and allows normal braking even if the ABS is not operating properly.

When the main switch is turned to “ON”, the ABS warning light comes on during the ABS self-diagnosis to check the electrical circuit of the light.
  • Page 30 FEATURES GEAR A.TEMP ˚C C.TEMP ˚C TIME TRIP 0:06 • Hydraulic unit assembly The hydraulic unit assembly “1” is composed of hydraulic control valves (each with a outlet solenoid valve and inlet solenoid valve), buffer chambers, hydraulic pumps, an ABS motor, and ABS ECU. The hydraulic unit adjusts the front and rear wheel brake fluid pressure to control the wheel speed accord- ing to signals transmitted from the ABS ECU.
  • Page 31 FEATURES 3. When the ABS ECU sends a signal to stop reducing the hydraulic pressure, the outlet solenoid valve “2” closes and the brake fluid is pressurized again. The inlet solenoid valve “1” controls the hydraulic pressure difference between the brake fluid in the upper brake lines (brake master cylin- der side) and the brake fluid in the lower brake lines (brake caliper side).
  • Page 32 FEATURES • ABS ECU The ABS ECU is integrated with the hydraulic unit to achieve a compact and lightweight design. As shown in the block following diagram, the ABS ECU receives wheel sensor signals from the front and rear wheels and also receives signals from other monitor circuits. 20 21 24 25 1.
  • Page 33 FEATURES ABS control operation The ABS control operation performed in the ABS ECU is divided into the following two parts. • Hydraulic control • Self-diagnosis When a malfunction is detected in the ABS, a fault code is stored in the memory of the ABS ECU for easy problem identification and troubleshooting.

  • Page 34: Abs Operation

    FEATURES ET3P61052 ABS OPERATION The ABS hydraulic circuit consists of two systems: the front wheel, and rear wheel. The following de- scribes the system for the front wheel only, excluding the unified brake system. Normal braking (ABS not activated) When the ABS is not activated, the inlet solenoid valve is open and the outlet solenoid valve is closed because a control signal has not been transmitted from the ABS ECU.
  • Page 35 FEATURES Emergency braking (ABS activated) 1. Depressurizing phase When the front wheel is about to lock, the outlet solenoid valve is opened by the “depressurization” signal transmitted from the ABS ECU. When this occurs, the inlet solenoid valve compresses the spring and closes the brake line from the brake master cylinder.
  • Page 36 FEATURES 2. Pressurizing phase The outlet solenoid valve is closed by the “pressurization” signal transmitted from the ABS ECU. At this time, the ABS ECU controls the opening of the inlet solenoid valve. As the inlet solenoid valve opens, the brake line from the brake master cylinder opens, allowing the brake fluid to be sent to the brake caliper.

    FEATURES ET3P61054 ABS WARNING LIGHT AND OPERATION ABS and UBS function EWA1MC1024 WARNING • When hydraulic control is performed by the ABS, the brake system alerts the rider that the wheels have a tendency to lock by generating a reaction-force pulsating action in the brake lever or brake pedal.

  • Page 41: Outline Of The Tcs (Traction Control System)

    FEATURES EAS1MC1082 OUTLINE OF THE TCS (Traction Control System) The traction control system controls excessive spinning (slipping) of the rear wheel when accelerating on slippery surfaces, such as unpaved or wet roads. The ECU monitors the front and rear wheel speeds using the signals from the front and rear wheel sen- sors, and detects rear wheel slipping according to the difference between the wheel speeds.
