2. What is the main function of ABS?

1. ABS prevents the wheels skidding when the handbrake is applied to a moving vehicle.

1. ABS monitors the airbag system and seatbelt pre-tensioners in case of an accident.

1. ABS is an air-brake system fitted to some vehicles as a supplementary braking system.

1. ABS (antilock braking system) prevents individual wheels from locking and skidding when the brakes are applied forcibly.

3. What is a body control unit?

1. Also known as the brake electrical module (BEM) or brake control module (BCM), the unit prevents the brakes from locking up under harsh operating conditions.
