ABS systems use a computer to monitor _________?

ABS systems use a computer that sends electrical signals to the ____ that momentarily hold orreleases hydraulic pressure to that wheel until it speeds up and starts rolling again.

The Electronic brake control (EBC) systems have greatly increased the safety of vehicles.

The ABS system was designed to make the wheels squeal loudly when the brakes are applied strongly.

Which component of the ABS system contains electric solenoid valves controlled by the EBCM to modify hydraulic pressure in each hydraulic circuit?

Either separate or combined into a common assembly, the isolation valve and dump valve are controlled by a (n) _______.

A _____ system uses separate speed sensors and hydraulic control circuits for each of the four wheels

If the high-pressure pump fails for any reason, the ________ holds enough brake fluid at high pressure to apply the brakes 10 to 20 times before the boost is used up.

A wheel sensor assembly consists of a toothed tone wheel (or tone ring) that rotates with the wheels and a stationary _____ attached to the hum or axle housing.

The height of the sine wave is called its _____.

What style of speed sensor is sometimes called a passive system since it is self-contained and needs no outside power to function?

Some ABS systems provide _____ throught the ABS warning lamp when a specific terminal is grounded or two specific terminals are shorted together.

An electronic stability control system may integrate a (n) _____ into the basic ABS and TCS systems

A type of wheel speed sensor that uses the principle of magnetic induction to create its signal.

A brake system in which the master cylinder, power booster, and HCU are all combined in a common unit.

A sensor that measures the amount of turning a driver desires. This information is used by the ESC system to know the driver's direction intent.

An Alphanumeric code system used to identify potential problems in a vehicle system

A storage container that holds pressurized brake fluid.

The valve in the HCU that either allows or blocks brake fluid that comes from the master cylinder from entering the HCU hydraulic circuit. Integral ABS system

A Brake system in which the master cylinder, power booster, and HCU are all separate units.

The computer that controls the electrical system in the body of a vehicle, including power windows, door locks, heating and A/C systems, and in some cases the EBC system.

The component that creates an electrical signal based on the speed of the vehicle, which is sent to the EBCM.

A sensor that measures the amount of roll around the vehicle's horizontal axis that a vehicle is experiencing

A device that creates an analog or digital signal according to the speed of the wheel.

A storage container designed to contain high-pressure liquids such as brake fluid.

A sensor that signals to the EBCM both the position and speed of the steering wheel.

A tool used to hold the proportioning valve open on some ABS HCU's.

The number of wheel speed sensor circuits and hydraulic circuits the EBCM monitors and controls.

A condition in which the front wheels are turned further than the direction the vehicle is moving and the front tires are slipping sideways toward the outside of the turne.

A condition in which the rear wheels are slipping sideways toward the outside of the turn.

The part of the wheel speed sensor that has ribs and valleys used to create an electrical signal inside of the pick-up assembly.

When a single cylinder is used for two pistons. A tandem master cylinder would be an example of two pistons in one bore.

A type of wheel speed sensor that uses an effect similar to a Hall effect sensor to create its signal.

Electronic stability control systems take the ABS and TCS systems the the next level by adding sensor information regarding the driver's directional intent.

Understeer occurs when the vehicle is turning more sharply than the front wheels are being steered

Applying the brakes too hard or on a slippery survace can cause the wheels to lock.

Maximum braking traction occurs when the wheels are rotating 20-25% slower than the vehicle speed.

Nonintegral ABS systems use a fairly standard tandem master sylinder and a typical vacuum or hydraulic power booster.

Some hydraulic control units use a single, three-position solenoid valve per circuit , while others use dual, two-position valves per hydraulic circuit.

The pick-up assembly and tone wheel do not touch each other; a small gap, called an air gap, must be maintained at the specified clearance

The magneto-resistive sensor does not function effectively below vehicle speeds of around 5 mph.

The brake switch is a normally open switch, meaning that if the switch is not affected by any outside force, electrical current will flow through it.

Many electronic stability control system-equipped vehicles also monitor signals from the throttle position sensor, vehicle speed sensor, and brake pedal position sensor to help prevent a loss of control of the vehicle.

In the quest for increased safety, manufacturers developed a series of electronic _____________ systems; the first-generation was the anti-lock brake system.

The _________ ________ system applies brake pressure to the slipping tire, which causes more of the engine's torque to be transmitted to the wheel or wheels with the most traction.

The _________ ________ system is designed to prevent wheels locking or skidding, no matter how hard the brakes are applied or how slippery the road surface, and to maintain steering control of the vehicle.

When the ignition switch is turned on, the ABS controller illuminates the yellow ABS warning lamp and performs an automatic _______________________________
