Exam 53: Antilock Brake, Traction Control, and Stability Control Systems

The ____________________ acceleration sensor monitors acceleration, deceleration, and cornering forces (the sideward movement of the vehicle while it is turning a corner).

The ____________________ provides access and/or control of vehicle information, operating conditions, and diagnostic information.

Brake service on an ABS-controlled vehicle is similar to that of a non-ABS-equipped vehicle.

A(n)______ stores hydraulic fluid to maintain pressure and provides residual pressure for power-assisted braking.

Electronic stability control (ESC)systems are being discussed. Technician A says the brake at the inside rear wheel is applied when the system detects an understeer condition. Technician B says ESC can increase traction. Who is correc t?

What is a lateral acceleration sensor?

When activated, the dump valve sends hydraulic pressure to the ______.

The most effective and most common ABS available is a two-channel system, in which sensors monitor the front and rear wheels.

Technician A says when the ignition switch is turned to the start position, both the red and amber brake warning lights should turn on. Technician B says after the engine starts, the amber ABS warning light should turn off after three to five seconds if the system passes its self-test. Who is correct?

Technician A says three-channel ABS systems have individual hydraulic circuits to each of the two front wheels, and a single circuit to the two rear wheels. Technician B says a three-channel ABS system has four sets of solenoids in the hydraulic unit. Who is correct?

Antilock brake systems can modulate the pressure to the brakes as often as _____ times per second.

Describe the common method to depressurize an antilock brake system.

Most of the service done to the brakes of an antilock brake system is identical to that in a conventional brake system.

A(n)____________________ is a numeric identifier for a fault condition identified by the ABS system's internal diagnostic system.

The majority of antilock brake systems use the integrated design.

G-force is a measurement of a vehicle's ____________________.

The yaw rate sensor and lateral accelerometer share the same housing and are located _____.

The signal produced by wheel speed sensors can be affected by radio frequency interference.

Technician A says in one-channel systems, the rear brakes on both sides of the vehicle are modulated at the same time to control skidding. Technician B says most single-channel systems have a wheel speed sensor at each rear wheel. Who is correct?

An accumulator is normally charged with ______.
