Electronic Brake Control Final Exam Questions with Correct Answers Latest Version 2025
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? - Answers Both Technician A
and Technician B
Technician A says that to test variable reluctance sensors, you first should disconnect the suspected
sensor, measure the resistance, and compare the readings to specifications. Technician B says that if the
resistance does not meet specifications, overhaul the sensor. Who is correct? - Answers Technician A
Which of the following is LEAST likely to be used to diagnose an anti-lock braking system fault? -
Answers Test light
Technician A says that bleeding an electronic brake control system is just like bleeding a 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? - Answers Technician A
All of the following are typically added to an anti-lock braking system to gain traction control
capabilities, EXCEPT: - Answers additional wheel speed sensors beyond those used for ABS operation
Wheel speed sensors should be checked for which of the following with a DVOM? - Answers All of the
answers listed
Which of the following typically reports the vehicle's speed to the electronic brake control module? -
Answers Vehicle speed sensor
Technician A says that removing and installing electric and hydraulic components of the EBC system is
normally only required when there is a fault within the HCU. Technician B says that many HCUs are
nonserviceable; they will need to be replaced as a unit. Who is correct? - Answers Both Technician A and
Technician B
ABS systems require a scan tool to read ______________ codes from the EBCM. - Answers fault
Technician A says that traction control systems can apply the brakes to reduce wheel slippage.
Technician B says that some traction control systems can increase engine power to reduce wheel
slippage. Who is correct? - Answers Technician A
Which of the following modules executes the commands of the anti-lock braking system control
module? - Answers Hydraulic control module
If there is a fault with the hydraulic control unit, typically the unit: - Answers is not serviceable in the
field
