(8) Start engine (TM 9-2320-366-10-1) and
allow vehicle to build air pressure.
(9) Perform STE/ICE-R Test #50 and note
reading on STE/ICE-R.
(10) If 55-65 PSI (380-440 kPa) is not present,
perform step (18) through (22).
(11) If 55-65 PSI (380-440 kPa) is present,
replace shuttle valve (para 17-30).
