Which control module signals the traction motor to convert to a generator during regenerative braking? A) BECM B) PCM C) ASS D) All of the above

The correct answer is B) PCM.<br /><br />The Powertrain Control Module (PCM) is responsible for signaling the traction motor to convert to a generator during regenerative braking. The PCM monitors the vehicle's speed, throttle, and other parameters to determine when regenerative braking is necessary. When the vehicle is decelerating, the PCM sends a signal to the traction motor to switch from a motor to a generator, allowing the vehicle's kinetic energy to be converted back into electrical energy and stored in the battery. This process helps to improve the vehicle's overall efficiency and range.
