This diagram represents a wave form from an inductive ABS sensor, As the wheel speed increases, the:

• voltage remains the same and the frequency increases
  

• voltage increases and the frequency increases

• voltage increases and the frequency remains the same

• voltage remains the same and frequency remains the same

During traction control operation

• the brake is rapidly applied and released on the spinning wheel until traction is regained

• the brake is applied on the non spinning wheel until traction is regained

• the brake is applied on the spinning wheel until traction is regained

• the brake is rapidly applied and released on the non spinning wheel until traction is regained

The definition of the term 'castor angle' is defined as

• inclination of the road wheel relative to the vertical axis, when viewed from the side of the vehicle

• angle of the road wheel steering axis relative to the vertical, as viewed from above the vehicle

• angle of the road wheel steering axis relative to the vertical, as viewed from the side of the vehicle

• inclination of the road wheel relative to the vertical axis, when viewed from the front of the vehicle

The electronic brake force distribution (EBD) system on a light vehicle controls the brake system by........

• controls the braking force at the wheels by measuring the load applied to the front and rear axles

• controls the braking force at the wheels by monitoring the slip ratio of the tyres on the road

• controls the braking force at the wheels by monitoring the condition of the road surface through moisture and temperature sensors

• controls the braking force at the rear wheels by reducing the brake force when the vehicle is unladen

An advanced ride control system, when applied to a light vehicle

• monitors the pitch of the vehicle and is over-ridden by the drivers throttle and brake inputs

• monitors the yaw of the vehicle and is over-ridden by the drivers throttle and brake inputs

• monitors the pitch of the vehicle and over-rides the drivers throttle and brake inputs

• monitors the yaw of the vehicle and over-rides the drivers throttle and brake inputs

When cornering, a vehicle with electronically controlled air suspension will,

• immediately provide more air pressure to the air springs on the outside of the bend

• provide more air pressure to the air springs on the outside of the bend after a short delay

• immediately provide more air pressure to the air springs on the inside of the bend
  

• provide more air pressure to the air springs on the inside of the bend after a short delay

The amount of assistance provided by an electronic power-assisted steering system is changed by

• changing the voltage delivered to the motor in relation to the steering input shaft torque

• changing the gear ratio between the steering column and torque control unit

• changing the current delivered to the motor in relation to steering input shaft torque

• Changing the gear ratio between the steering column and steering rack

One advantage of a vehicle fitted with EPAS over a vehicle fitted with hydraulic power steering is

• less steering effort

• no torque sensing required

• reduced steering rack ratio

• improved fuel economy

The diagram shows the layout of a communication network froma light vehicle. The system operates by

• each control unit sending and receiving varying resistances through the data-bus

• each control unit sending and receiving data packets through the data-bus

• each control unit sending and receiving varying voltages through the data-bus

• each control unit working completely independently from the others

On a vehicle fitted with an EPAS system the component that senses the drivers turning effort is a

• torque sensor

• control pump

• steering speed sensor

• flow control valve
