components that originally did not pass the functional
check--out (now using an identical spare component in
its place).
Change out the HDC system component that did not
pass the functional check--out with an identical, known
good spare, component (solenoid valve or pressure
transducer, as applicable) or temporarily switch
identical type components from another nearby
location in the HDC system.
Did the functional check--out test fail again for the
same component designator as it did for the original
