This trainer provides students and instructors with the opportunity to demonstrate, investigate and fault-find a simulation of a typical 4-wheel anti-lock braking system.

The trainer is designed to demonstrate ABS hydraulic and electrical system operation, as well as provide the ability to simulate changes in road conditions that impact ABS operation. To facilitate the development of techniques in diagnostics and fault-finding skills, the panel includes a range of fault-insertion options to simulate typical real-world system malfunctions.

This resource is supplied with a curriculum manual CD containing practical tasks and activities.

The trainer can also be used in conjunction with our optional cloud-based software, which offers online practical tasks as well as interactive theory presentations, investigations, and assessments, which link directly to practical activities carried out using this resource.

Typical Practical Tasks Include:

• Principles of braking systems and vehicle acceleration/deceleration
• Identify the phases of ABS operation
• Test the operation of ABS sensors and switches
• Concepts of wheel spin and slip
• Effects of slip on wheel braking and vehicle stability
• Basic concepts of an ABS system
• Static operation of an ABS system, covering pressure isolation, pressure dump, pressure increase and pressure normal
• Dynamic operation of an ABS system in real time
• The ABS hydraulic circuit and solenoid operation
• ABS wheel sensors – evaluate Hall Effect and inductive sensors
• Electronic signals in an ABS system
• Operation of an electronically-controlled hydraulic modulator
• ABS control unit (ECU) operation
• Sensor operation and fault diagnosis
• Diagnosis of system faults
• ABS system fault-code reading using on-board fault-code scanner
• Troubleshooting the hydraulic modulator
