The power door lock system does not operate. Technician A says faulty unlock relay contacts could be the cause. Technician B says a faulty motor could cause this. Who is correct?

Question

Quizplus · Accepted Answer

Faulty unlock relay contacts could cause the power door lock system to fail, as the relay controls the lock/unlock function. A faulty motor would only affect the lock and/or unlock function of one specific door, whereas this question is specifically asking about the entire power door lock system. Therefore, Technician A is correct and Technician B is not relevant to the issue described.
