4.11.4 PF Valve Assembly R&R
To determine whether each PF assembly is functioning properly, use the SAM Pump Controller
MIV Diagnostic Screen (password 6060). Select the OUTPUT screen and look for the Pre-Prime 1
thru 4, Prime Body, or AB Drain icons. With the 4-way air valve connected to the SAM harness,
touch the applicable icon. On the diagnostic screen, each time the icon toggles state, listen/feel
for a distinctive click on the corresponding 4-way air valve and visually monitor for movement of
the air cylinder at the PF valve assembly.
Once a PF valve failure has been determined use this procedure to R&R the failed valve.
Refer to Table 72 for a list of tools and/or consumables required for this procedure.
