Which additional monitoring does modern legislation require on board?

  • A.Continuous monitoring of emissions related components
  • B.Periodic testing at a garage, which is the only means by which the emissions performance may be verified in service
  • C.None
  • D.Diagnostics that detect any deterioration causing emissions to exceed a threshold, illuminating a lamp to warn the driver

Answer: A

On board diagnostics must detect deterioration and warn the driver before emissions exceed a defined multiple of the limit. The last option states that requirement precisely, which makes it a correct and more formal version. Checking which component actually carries the load settles most questions of this kind at once. The order in which the effects act is what decides the outcome, so it is worth establishing first.
