FEATURES EAS20170 FEATURES EAS5D01032 OUTLINE OF THE FI SYSTEM The main function of a fuel supply system is to provide fuel to the combustion chamber at the opti- mum air-fuel ratio in accordance with the engine operating conditions and the atmospheric tempera- ture.
FEATURES EAS5D01013 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/cm , 46.1 psi). Accordingly, when the energizing signal from the ECU energizes the fuel injector, the fuel passage opens, caus- ing the fuel to be injected into the intake manifold only during the time the passage remain open.

FEATURES Useful terms • Wheel speed: The rotation speed of the front and rear wheels. • Chassis speed: The speed of the chassis. 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. •...

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 condition and allows normal braking even if the ABS is not operating properly.

FEATURES ABS control operation The ABS control operation performed in the ABS ECU is divided into the following two parts. • Hydraulic control • Self-diagnosis These operations are performed once every 8/1000th of a second. When a failure is detected in the ABS, a malfunction code is stored in the memory of the ABS ECU for easy problem identification and troubleshooting.
Page 26
FEATURES Composition and operation The ABS motor relay is activated by signals transmitted from the ABS ECU and operates simulta- neously when the ABS starts to reduce the hydraulic pressure of the brake fluid. If the solenoid relay is turned off, the ABS motor relay is also deactivated and the motor stops operating if there is a mal- function.

FEATURES Emergency braking (ABS activated) 1. Depressurized state When the front wheel is about to lockup, port D “11” of the solenoid valve is opened by the “depressurization” signal transmitted from the ABS ECU. When this occurs, the spool of the flow control valve compresses the return spring and closes port B “9”.

FEATURES c. Goes off a. ABS warning light d. Preparation b. Comes on 4. The ABS warning light “1” flashes and a malfunction code “2” is indicated on the multi-function display when the test coupler adapter “3” is connected to the ABS test coupler “4” for trouble- shooting the ABS.
Page 33
FEATURES B. FZ1-NA A. FZ1-SA • Diagnosis indication The place where the ABS diagnosis code is displayed is also used for the indication of the FI diag- nosis code, odometer, trip meter and fuel trip. As the priority level of indication, the diagnosis code for FI is the first and the diagnosis code for ABS is the second.
Page 34
FEATURES ABS function • A brake system in which the hydraulic control has been performed by the ABS alerts a rider that the wheels had a tendency to lock by generating a reaction-force pulsating action in the brake lever or brake pedal. When the ABS is activated, the grip between the road surface and tires is close to the limit.
EAS20200 REPLACEMENT PARTS Use only genuine Yamaha parts for all replace- ments. Use oil and grease recommended by Yamaha for all lubrication jobs. Other brands may be similar in function and appearance, but inferior in quality.

IMMOBILIZER SYSTEM e. Standby mode on f. Standby mode off Standard key registration: Standard key registration is required when a standard key is lost and needs to be replaced, or when the code re-registering key is re-registered after the immobilizer unit or ECU are replaced. NOTE: Do not start the engine with a standard key that has not been registered.
Page 453
IMMOBILIZER SYSTEM Voiding the standard key code: If a standard key has been lost, it is possible to disable its use by re-registering the remaining stan- dard key. Standard key registration erases the stored standard key code from the memory, thus dis- abling the lost standard key.
