Exam 59: Anti-Lock Brakes Traction and Stability Control

A pulsating pedal during a non-ABS stop could be due to a warped brake drum or thickness variations in a disc rotor.

Which of the following is LEAST-Likely to be monitored by computer modules as part of an ESC program?

While having a discussion, Technician A says that having a sensor at each wheel means that the ABS is four channel. Technician B says that having a sensor at each wheel does not necessarily mean that the ABS is four channel. Some three-channel systems have four-channel braking. Who is correct?

All of the following statements are true EXCEPT:

If a wheel locks up, a(n) ____________________ pulsates the pressure to that wheel in much the same manner as a race car driver pumps the brakes during a turn to avoid a skid.

____ is when the ABS operates when it is not supposed to.

Most newer cars are equipped with computerized ____________________ to limit the amount the wheels can lock up.

How can you reduce an engine's power output?

While having a discussion, Technician A says that the majority of ABS problems result from failure of a wheel speed sensor. Technician B says that some wheel speed sensors fail because of exposure to harsh operating conditions, and others fail due to abuse. Who is correct?

AC waveforms are prone to radio frequency interference (RFI) with their signals.

All of the following statements are true EXCEPT:

The sensor that is MOST-Likely used on some antilock systems to measure "yaw" forces encountered while turning is the:

The integral ABS brake system reservoir is usually much smaller than a normal brake system reservoir.

Which of the following statements is LEAST-Likely true?

The tool that will MOST-Likely ask you to check a wheel speed sensor for AC voltage output is the:

Many rear-wheel-drive ABS vehicles have a sensor mounted in the differential.

During a two-wheel ABS stop, the isolation valve closes to prevent further hydraulic pressure from reaching the ____.

____________________ applies the brakes to a wheel that is spinning in mud or on ice, sending the torque to the wheel on the other side of the vehicle.

The ABS is sometimes used to limit the amount the wheels can spin during acceleration. This is called a(n) ____________________ or acceleration slip regulation (ASR).

List five components of hydraulic circuitry.
