What type of output signal do most inductive type sensors produced when tested with an oscilloscope?:

• A Sine Wave

• Square wave

• Heelo wave

• Goodbyee wave

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

:

• EPAS is heavier
• EPAS is less responsive
• EPAS is more fuel-efficient
• EPAS requires more maintenance

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

• Voltage and the frequency increase with the wheel speed until it reaches approximately 10kph and than voltage becomes constant(0.25V) and frequency changes with speed.

• amplitude of the wave form increases
• velocity of the wave form increases
• frequency of the wave form increases

A front wheel drive vehicle has a fault which causes the yellow traction control light to be illuminated when driving and the vehicle lacks power. On initial inspection you notice that the rear tyre profiles are larger than the front tyres. The fault is most likely to be

• Faulty engine control unit
• Loose wheel nuts
• Damaged suspension components
• Larger rear tyre profiles causing speed difference between front and rear wheels

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

• temperature sensor
• pressure sensor
• speed sensor
• torque sensor

If the pump should fail in a hydraulic power assisted steering system:

State effect on mechanical system?

• Loss of power assistance in steering
• Decrease power assistance in steering
• No effect on steering
• The mechanical steering system must still be able to operate

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

• Enhances stability, comfort, and handling by adjusting suspension and damping settings.
• Has no impact on handling as it only focuses on aesthetics
• Decreases stability and comfort by limiting suspension adjustments
• Increases fuel consumption by reducing damping settings

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

• Enhances stability, comfort, and handling by adjusting suspension and damping settings based on road conditions and driving dynamics.
• Increases the risk of accidents by not adjusting damping settings based on driving dynamics
• Improves fuel efficiency by reducing handling capabilities
• Decreases stability and comfort by keeping suspension settings constant regardless of road conditions

A four wheel steer vehicle has feathered wear on both outer edges of the rear tyres. The rear rack and pinion is mounted in front of the rear axle.

To correct the fault, the technician will need to:

• Adjust the rear toe alignment Increase the length of the rear track rods

• Replace the front tires
• Adjust the front toe alignment
• Check the engine oil level

An ABS control unit calculates that a wheel is about to lock by:

• Monitoring the wheel speed using sensors and comparing it to the vehicle speed
• Checking the tire pressure
• Sensing a sudden drop in A C Voltage from a wheel sensor.

• Measuring the fuel consumption
