Answer :
Answer:
Option B.
Technician B Only is correct
Explanation:
Traction Control systems are systems in a vehicle that are deigned to optimize grip and stability of the car on the road during acceleration by measuring wheel rotation.
Traction systems are designed to work during acceleration, not deceleration. this makes Technician A wrong.
Traction control systems are pretty much active up to a manufacturer-specified speed. Above that speed, the traction control is deactivated by the electronic brake control module because further acceleration is unlikely to cause the wheels to lose traction. This makes Technician B correct
The correct option to this question is B, which is Technician B only.
Looking to the statements again,
Technician A - The traction control system was developed to prevent the drive wheels from slipping while the vehicle is being decelerated when coming to a stop.
which is a wrong statement,
Explanation:
A traction control system (TCS), or ASR , is a secondary function of the electronic stability control (ESC). It was designed to prevent loss of traction (wheel spin) of the driven road wheels. TCS activates when throttle input, engine power and torque transfer are mismatched to the road surface conditions. Also, traction control is used as a performance enhancement, allowing maximum traction under acceleration without wheel spin. When accelerating out of a turn, it keeps the tires at optimal slip ratio.
Technician B - Above a manufacturers specified speed, the traction control system deactivates.
which is a correct statement,
Explanation:
Traction control systems activation depends on manufacturer specified speed. If the vehicle crosses that specified speed, the traction control is deactivated by the electronic brake control system because after that acceleration will cause the wheels to lose traction.
Hence, the statement of only technician B is true or valid.
