Which procedure often follows climate control component replacement?

  • A.A self calibration in which each motor is driven to its stops so the controller learns the travel available
  • B.A flap position calibration run
  • C.Nothing, since the motors find their own positions during normal operation and therefore need no calibration
  • D.A road test

Answer: B

Driving each flap to its limits teaches the controller the range. The last option describes exactly that routine, which makes it a correct and more detailed version of the same answer. Checking which component actually carries the load settles most questions of this kind at once. 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 summary, avoids the usual confusion.
