Traction Control: Anti-Lock: Description

The Anti-Lock Brake System (ABS) is designed to prevent wheel lock-up during heavy braking. This allows operator to maintain steering control while stopping vehicle in shortest distance possible. Major components are wheel speed sensors, ABS Electronic Control Unit/Hydraulic Unit (ABS ECU/HU) and ANTI-LOCK warning light. ABS has a self-diagnostic system to indicate a system malfunction and for use in system trouble shooting.

Electronic Brakeforce Distribution (EBD) control has been added to provide ideal braking force for rear wheels. EBD is a control system which provides a high level of control for both vehicle braking force and vehicle stability. EBD system has following features:

• Fail-safe function which ensures that safety is maintained.
• Self-diagnosis function which provides improved serviceability.
• Because system provides optimum rear wheel braking force regardless of the vehicle laden and road surface condition, the system reduces required pedal depression force, particularly when vehicle is heavily laden or driving on road surfaces with high frictional coefficients.
• Because the duty placed on the front brakes has been reduced, the increases in pad temperature can be controlled during front brake application, improving wear resistance characteristics of brake pads.
• Control valves, such as the proportioning valve, are no longer required.
