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

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

Identify the resource for determining ABS brake bleeding procedures and why it should always be used.

With ABS, the brake pedal feel during hard [panic stop] braking is similar to that of a conventional power brake system.

The rapid application and release of brake pressure used to prevent wheel lock is called ____________________.

Automatic traction control (ATC) is being discussed. Technician A says vehicles with ATC typically do not have an antilock brake system. Technician B says ATC applies extra torque to a drive wheel that is spinning and losing traction. Who is correct?

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

All vehicles have a(n) ____________________colored warning lamp to indicate a problem in the vehicle's conventional brake system.

Explain the difference between oversteer and understeer.

Before removing the master cylinder on an ABS system with a high-pressure accumulator, the accumulator must be discharged by ______.

The modulator unit is sometimes called a(n) ______.

Which of the following is NOT a component of an antilock brake system?

Explain the role of the wheel sensors in an antilock brake system.

When the vehicle is road tested after replacement of an axle shaft, the ABS warning light turns on. Technician A says count the number of teeth on the toner ring of the old axle and compare it to the new axle. Technician B says perform an ABS speed sensor relearn procedure. Who is correct?

Pumping the brake pedal quickly during ABS activation will assist the antilock brake system to function properly.

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

What is the primary difference between automatic traction control systems and stability control systems?

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

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

An accumulator unit is typically found on vehicles with _____.
