Understanding ABS System Components

What is the primary function of an Anti-lock Braking System (ABS) in light vehicles?

• To increase the speed of the vehicle

• To prevent the wheels from locking during braking

• To enhance fuel efficiency

• To improve the vehicle's aerodynamics

Which component of the ABS is responsible for detecting wheel speed?

• Brake pedal

• Wheel speed sensor

• Hydraulic pump

• Control module

What role does the ABS control module play in the system?

• It applies the brakes

• It monitors wheel speed and controls brake pressure

• It inflates the tyres

• It changes the vehicle's direction

Which component of the ABS modulates brake pressure to prevent wheel lock-up?

• Brake caliper

• Hydraulic pump

• Master cylinder

• Brake disc

What is the function of the ABS hydraulic unit?

• To store brake fluid

• To modulate brake pressure

• To increase engine power

• To cool the brakes

How does the ABS improve vehicle safety?

• By reducing fuel consumption

• By maintaining steering control during emergency braking

• By increasing tyre wear

• By enhancing engine performance

Which of the following is NOT a component of the ABS?

• Wheel speed sensor

• Control module

• Air filter

• Hydraulic pump

What happens when the ABS is activated?

• The vehicle accelerates

• The brake pedal becomes softer

• The brake pressure is modulated to prevent wheel lock-up

• The engine shuts down

Which component sends signals to the ABS control module?

• Brake light

• Wheel speed sensor

• Fuel injector

• Exhaust manifold

What is the purpose of the ABS warning light on the dashboard?

• To indicate low fuel

• To show that the ABS is functioning properly

• To alert the driver of a potential ABS malfunction

• To signal a tyre pressure issue
