13. If all the input tests prove OK, one of the control units must be faulty. Substitute a known-good control unit for the
one that is most likely at fault, then recheck the system. If the system works properly, the original control unit is
faulty; replace it. If there is still a malfunction, substitute a known-good control unit for the next unit most likely to
be at fault, and recheck. If the system works properly, the original unit is faulty; replace it.
