Question

Quizplus · Accepted Answer

Technician A is correct because OBD-II monitor readiness typically requires a vehicle to be driven through a specific drive cycle that includes various conditions such as idle, low-speed cruise, medium-speed cruise, and deceleration to perform all monitors. Technician B's statement that all monitors can be performed in five minutes of fast idling is incorrect, as this does not meet the conditions required for all monitors to run.
