Technician A says an I/M 240 test is four minutes long. Technician B says the test cycle includes acceleration, deceleration, and cruising on an actual road test. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is correct because the I/M 240 test, which stands for Inspection/Maintenance, is indeed a 240-second (or four-minute) test designed to simulate real driving conditions on a dynamometer to measure vehicle emissions. Technician B is incorrect because the test cycle simulates these conditions but does not involve an actual road test; it's conducted on a dynamometer in a controlled environment.
