Tech A says that the purpose of an anti-lock braking system is to prevent the wheels from locking during braking, especially on low-friction surfaces such as wet, icy, or snowy roads. Tech B says that the anti-lock braking system does not mean a vehicle can stop quickly on all road surfaces. Who is correct?
A. 
B. 
C. 
D.

10.
On a vehicle with an electronic brake control module, if the yellow warning lamp is not illuminated and the brakes are not functioning properly, suspect a problem that is not monitored by the electronic brake control module.
11.

A. 
B. 
Not serviceable in the field
C. 
D. 
14.
Wheel speed sensors send electric signals to the electronic brake control module to determine the speed and rate of deceleration of each wheel.
15.
Wheel sensor assemblies are comprised of a toothed tone wheel and a pick-up assembly, separated by a metal plate.
16.
Tech A says that all traction control systems apply the brakes as a first step and reduce engine power. Tech B says that some traction control systems do not apply the brakes as a first step but reduce engine power. Who is correct?
A. 
B. 
C. 
D. 
17.

A. 
B. 
C. 
D. 
18.
Tech A says that if the yellow warning lamp is illuminated indicating a fault in the electronic brake control system, you should retrieve the diagnostic trouble codes and follow the procedure listed in the service information. Tech B says that if the yellow warning lamp is not illuminated and the brakes are not functioning properly on a vehicle with an electronic brake control system, you should suspect a problem that is not monitored by the electronic brake control module. Who is correct?
A. 
B. 
C. 
D. 
19.
Which of the following is MOST likely to be in an electronic brake control module?
A. 
B. 
C. 
D. 
20.

A. 
B. 
C. 
D. 
21.
Tech A says that bleeding an electronic brake control system is just like bleeding a non–electronic brake control system. Tech B says that if the air is allowed into the electronic brake control system, it can become trapped in the hydraulic control unit, requiring a scan tool to operate the solenoid valves to help bleed the air from the electronic brake control system. Who is correct?
A. 
B. 
C. 
D. 
22.

A. 
B. 
C. 
D. 
23.
Tech A says that some anti-lock braking systems do away with the mechanical proportioning valve. Tech B says that the electronic brake control module performs an automatic self-check and warning lamp bulb check on the anti-lock braking system every time the key is turned to the “run” position. Who is correct?
A. 
B. 
C. 
D. 
24.
