Which on board requirement accompanies the standards?

  • A.None, since the vehicle is tested periodically and therefore requires no diagnostic capability of its own
  • B.Only a lamp
  • C.A monitoring system detecting any fault that would raise emissions beyond a threshold and warning the driver
  • D.Diagnostics detecting emissions relevant deterioration

Answer: D

On board diagnostics must detect deterioration and warn the driver. The last option states that requirement precisely, which makes it a correct and more detailed version of the same answer. The order in which the effects act is what decides the outcome, so it is worth establishing first. Naming what changes and what stays the same is the reliable route through questions of this shape. Reading the definition literally, rather than recalling a formula, is the reliable route through questions of this shape.
