Diagnose and repair faults in dynamic control systems of vehicles. These systems include the functions of a vehicle electronic braking control module (EBCM), such as anti-lock braking, brake assist, descent control, electronic brake force distribution, electronic park brake, hill start assist, stability control, traction control and active roll-over protection. The unit involves preparing for the task, selecting the correct diagnostic procedure, carrying out the diagnosis and the repair, performing post- repair testing, and completing workplace processes and documentation.

Chapter 1 General Health and Safety Appropriate PPE is to be worn at all times Identify and control risks as required If any fire starts, first isolate the source only if safe to do so Evacuate under the instructions of your warden

Electrical Health and Safety If an electrical fire starts, first you must isolate the power source, only if it is safe to do so. Not all fire extinguishers are appropriate to use on an electrical fire as the contents of some extinguishers are conductive and may cause electrocution if used. If the fire is larger than the capability of your extinguisher, sound the alarm, and evacuate under the instructions of your warden.

Chapter 2 Anti-Lock Braking Systems Vehicle Dynamic Control (VDC) is a term used to describe a group of electronic systems that work together in maintaining enhanced control over a vehicle’s dynamic movement. Braking Cornering Acceleration

Chapter 2 Anti-Lock Braking Systems Maximum braking efficiency can usually be found at around 10 -20% slip. Past this point though, braking efficiency drops markedly and increases the chance of complete lock up (100% slip).

Chapter 2 Anti-Lock Braking Systems When the brakes are depressed, the control unit compares the signals from each individual wheel speed sensor. If tyre slip exceeds a certain limit, it modulates braking pressure to the necessary wheel(s) until slip returns to within an acceptable level

Chapter 2 Anti-Lock Braking Systems ABS Control Module The ABS module will use an array of input devices to monitor and measure, then use output devices to control the system

Chapter 2 Anti-Lock Braking Systems Brake Switch As the brake pedal is depressed, the switch will either make or break a connection, signalling the drivers intention to slow the vehicle - only then will the ABS module begin to monitor and trigger VDC protocols

Chapter 2 Anti-Lock Braking Systems Wheel Speed Sensor The most critical input for ABS is that from the wheel speed sensors

Chapter 2 Anti-Lock Braking Systems An inductive type sensor produces an AC voltage, the voltage increases as the speed increases. This is known as a
