ATC systems are being discussed. Technician A says in order to use the brakes to control wheel spin, the ABS must have a pump to develop hydraulic pressure and an accumulator to store reserve pressure. Technician B says the pulse rings and wheel-speed sensors for ATC systems are located inside the transmission and are different from ABS wheel speed sensors. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because ATC (Automatic Traction Control) systems indeed use the vehicle's ABS system to control wheel spin, which requires a pump to generate hydraulic pressure and an accumulator to store it. Technician B is incorrect because pulse rings and wheel-speed sensors for ATC systems are typically located at the wheels, not inside the transmission, and are the same or similar to those used in ABS systems.
