  • Page 66: Anti-Lock Brake System (Fjr1300A)

    ABS OUTLINE Yamaha ABS features 1. The Yamaha ABS (Anti-Lock Brake System) features a dual electronic control system, which acts on the front and rear brakes independently. 2. The ABS features a compact and lightweight design to help maintain the basic maneuverability of the motorcycle.
  • Page 67 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) EAS00872 The operation of the Yamaha ABS brakes is the same as conventional motorcycles, with a brake lever for operating the front wheel brake and a brake pedal for operating the rear wheel brake. When wheel lockup is detected during emer- gency braking, hydraulic control is performed by the hydraulic system independently.
  • Page 68 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) • Slip ratio: When the brakes are applied, slipping occurs between the tires and the road sur- face. This causes a difference between the wheel speed and the chassis speed. Slip ratio is the value that shows the rate of wheel slippage and is defined by the follow- ing formula.
  • Page 69 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) EAS00875 Wheel slip and hydraulic control The ECU (ABS) calculates the wheel speed of each wheel according to the rotation signal Motorcycle speed received from the front and rear wheel sen- sors. In addition, the ECU (ABS) calculates the motorcycle chassis speed and the rate of speed reduction based on the wheel speed Wheel speed...
  • Page 70 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) The higher the cornering force on a tire, the Brake force less traction there is available for braking. This is true whether the motorcycle is equipped with an ABS or not. Therefore, sudden braking while cornering is not recommended. Exces- Side force sive cornering force, which an ABS cannot pre- vent, could cause the tire to slip sideways.
  • Page 71 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) EAS00877 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 providing various travel conditions for motorcy- cles. The ABS also includes a highly developed self-diagnostic function. The ABS detects any problem conditions and allows normal braking even if the ABS is not operating properly.
  • Page 72 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) EAS00878 ABS component functions • Wheel sensors and sensor rotors Wheel sensors 1 detect the wheel rotation speed and transmit the wheel rotation signal to the ECU (ABS). Each wheel sensor is composed of a perma- nent magnet and a coil.
  • Page 73 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) EAS00879 • Hydraulic unit The hydraulic unit 1 is composed of a hydrau- lic control valve (solenoid valve, flow control valve), a buffer chamber, and a hydraulic pump for each brake and an ABS motor. The hydraulic unit adjusts the front and rear wheel brake fluid pressure to control the wheel rota- tion speed according to signals transmitted...
  • Page 74 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) • Hydraulic control valve The hydraulic control valve is composed of a flow control valve and solenoid valve. When the ABS is activated, the flow control valve regulates the flow of brake fluid to each brake and the solenoid valve decreases and increases the brake fluid pressure.
  • Page 75 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) • Buffer chamber The buffer chamber accumulates the brake fluid that is depressurized while the ABS is operating. 1 Buffer chamber (pressurized) 2 Buffer chamber (depressurized) 3 Raised piston • Electronic control unit (ECU) The ECU (ABS) 1 controls the ABS and is installed under the tray bracket.
  • Page 76 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) As shown in the block diagram below, the ECU (ABS) receives wheel sensor signals from the front and rear wheels and also receives signals from other monitor circuits. Both a main microcomputer and a sub microcomputer are installed in the ECU (ABS) to provide mutual monitoring. 1 Battery A Main switch K Meter assembly...
  • Page 77 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) • ABS control operation The ABS control operation performed in the ECU (ABS) is divided into the following two parts. • Hydraulic control • Self-diagnosis These operations are performed once every 8/1,000 of a second. When a failure is detected in the ABS, a malfunction code is stored in the memory of the ECU (ABS) for easy problem identification and troubleshoot-...
  • Page 78 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) • Fail-safe relay The fail-safe relay controls the power supply of the hydraulic unit and is located beside the hydraulic unit. 1 Fail-safe relay Composition and operation The fail-safe relay is composed of the solenoid relay 1 and ABS motor relay 2. The solenoid relay is activated (continuous) by signals transmitted from the ECU (ABS).
  • Page 79 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) ABS operation The ABS hydraulic circuit consists of two systems: the front wheel and rear wheel. The following describes the front system only. • Normal braking (ABS not activated) When the ABS is not activated port D A of the solenoid valve is closed because a control signal has not been transmitted from the ECU (ABS) and port A 7 and port B 9 of the flow control valve are open.
  • Page 80 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) • Emergency braking (ABS activated) 1) Depressurized state When the front wheel is about to lockup, port D A of the solenoid valve is opened by the “depres- surization” signal transmitted from the ECU (ABS). When this occurs, the spool of the flow control valve compresses the return spring to close port B 9.
  • Page 81 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) 2) Pressurized state Port D A is closed by the “pressurization” signal transmitted from the ECU (ABS). Before this occurs, the spool of the flow control valve has compressed the return spring to close port B 9. Brake fluid that has entered through port A 7 is further restricted by the orifice 0 and the brake fluid is sent to the brake calipers via port A 7 and port C C.
  • Page 82 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) EAS00880 Self-diagnosis function • ABS warning light The ABS warning light 1 comes on when a malfunction is detected by the ABS self-diag- nosis. It is located in the meter assembly. • Instances when the ABS warning light comes on 1) The ABS warning light comes on when the Main switch Main switch...
  • Page 83 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) 4) The ABS warning light 4 flashes and mal- function code 3 is indicated on the multi- function display when a test coupler adaptor 2 is connected to the 4-pin test coupler 1 for troubleshooting the ABS. The 4-pin test coupler can be accessed by removing the right inner panel (front cowl- ing).
  • Page 84 CHAS ANTI-LOCK BRAKE SYSTEM (FJR1300A) Cautions for operation ABS warning light: • When the main switch is set to “ON”, the ABS warning light comes on for 2 seconds, then goes off. • If the ABS warning light comes on while riding, stop the motorcycle, and then set the main switch to “OFF”, then set the main switch to “ON”.
