 Thus the benefit of forking over $80+ for the Bentley service manuals. By
 my recollection over 40 pages are dedicated to this diagnostic sequence -
 far too many for my current schedule to type into the net. BTW the diagnostics
 told me that there was no problem when my AC was anemic due to a need for
 a new freon charge...
