Question

Quizplus · Accepted Answer

Automatic Traction Control (ATC) systems are designed to prevent wheel spin during acceleration by automatically adjusting the power output to the wheels. These systems often work in conjunction with Antilock Brake Systems (ABS), contrary to Technician A's statement. Technician B is incorrect because ATC does not apply extra torque to a spinning wheel; instead, it typically reduces engine power or applies the brakes to the spinning wheel to prevent loss of traction.
