Stability control and hydraulics

Multiple Select

What are the purposes of an ESP system ?

• To increase fuel efficiency
• The purposes of an ESP system are to improve vehicle stability, prevent skidding, and enhance overall safety during driving.
• To enhance engine performance
• To improve audio quality in the vehicle
• to improve tyre wear.

Multiple Choice

What is yaw rate ?

• Yaw rate is the distance traveled by a vehicle over time.
• Yaw rate measures the acceleration of a vehicle.
• Yaw rate is the speed of a vehicle in a straight line.
• Yaw rate is the angular velocity around the vertical axis of a vehicle.

How do you diagnose a steering angle sensor ?

• Check for DTCs.

• Replace the sensor with a new one immediately
• Ignore any error codes and drive the vehicle
• Only check the tire pressure before diagnosing
• Use a multimeter to measure voltage as you turn the wheel.

Multiple Choice

you can use a oscilloscope to test a steering angle sensor.

• True

• False

What makes up an inductive sensor ?

• a resistor

• a permanent magnet

• an iron core

• a coil

• a sensor

Multiple Choice

Why is a lateral acceleration mounted close to the centre of gravity ?

• To increase the response time of the vehicle.
• To measure vertical forces more effectively.
• A lateral acceleration sensor is mounted close to the center of gravity to ensure accurate measurement of lateral forces without interference from rotational movements.
• To reduce the weight of the sensor system.

Multiple Choice

Why might the hydraulic control unit and ESP unit not be mounted together?

• Space constraints and differing operational requirements.
• They require the same power source.
• They are designed to operate in tandem.
• They are both too large to fit anywhere.

Multiple Choice

• pressure increase

• pressure decrease

• pressure hold

• pressure stop

• pressure variable
