CDX - Brakes Questions With Solutions
The _____ system was designed to prevent wheels from locking up under braking
conditions and shorten most panic stop distances. - ANSWER>>ABS
Electronic brake control (EBC) systems have greatly increased the _____ of
vehicles over the years. - ANSWER>>Safety
The first-generation EBC system was the _____, which was designed to prevent
wheels from locking up under braking condtions. - ANSWER>>ABS
Tech A states that traction control capability can help prevent loss of driving
control and vehicle rollovers. Tech B states that ABS shortens most panic stop
distances. Who is correct? - ANSWER>>Both A and B
Which of the following is MOST likely to be in an electronic brake control module?
- ANSWER>>Electronic circuitry; computer memory; output drivers
In addition to activating the rear brake lights, the brake switch sends an electrical
input signal to the _____, telling it if the driver is applying the brakes or not. -
ANSWER>>EBCM
The TCS sensors are the same in the ABS system, but the ability to apply the
individual drive wheel brakes is needed; thus, two to four extra solenoid valves,
called _____, are added to the HCU. - ANSWER>>Boost valves
Which of the following is/are typically added to an anti-lock braking system to
gain traction control capabilities? - ANSWER>>High-pressure electric pump; boost
valves; programming
, The brake switch is an on/off switch that informs the EBCM of whether or not the
driver is applying the brakes. - ANSWER>>True
Tech A says that bleeding an electronic brake control system is just like bleeding a
non-electric brake control system. Tech B says that if 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? - ANSWER>>Both Techs
A and B
Technician A says that bleeding an electronic brake control system is just like
bleeding non-electronic brake control system if care is taken to never allow air to
enter the hydraulic system. Technician B says that bleeding air manually from an
electronic brake control system is easier than bleeding air from non-electronic
brake control systems. Who is correct? - ANSWER>>Technician A
If care is taken to never allow air to enter the hydraulic system, most EBC systems
can be bled just like a non-EBC system. - ANSWER>>True
Technician A says that to depressurize high-pressure components of the
electronic brake control (EBC) system, research the procedure for depressurizing
the accumulator in the service information. Technician B says to remove the ABS
fuse from the fuse box and apply the brake firmly at least 40 times when
depressurizing the components of the EBC system. Who is correct? -
ANSWER>>Both Technician A and Technician B
When depressurizing the accumulator and verify that the ignition switch is in the
off position, depress the brake pedal _____ times. - ANSWER>>30 to 50
Technician 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. Technician B
says that once the fault has been corrected, clear the diagnostic code and verify
