Which evidence justifies replacing a control module?

  • A.Proven supply and bus with the module still not responding
  • B.A fault code naming the module, which is sufficient evidence that the module itself has failed in service
  • C.Customer request
  • D.Confirmed power, earth and bus wiring together with an absence of response to a correctly addressed request

Answer: A

Everything external must be proved sound before the module is blamed. The last option states that evidence in full, which makes it a correct and more rigorous version of the same answer. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. Naming what changes and what stays the same is the reliable route through questions of this shape. Most errors here come from carrying across a result from a neighbouring case where it does not hold.
