#2
Circuit Info Latch
“Service Messages”
enabled
Diagnostic occurs when accumulated circuit
operating hours since last initialized exceeds
2000 hours. Diagnostic can be manually
cleared but will reoccur every month (720
hours on real time clock) as long as
accumulator is not re-initialized.

Circuit Info Latch
“Service Messages”
enabled
Diagnostic occurs only when “service
messages” are enabled and when Oil Filter Life
remaining falls below 5%. Diagnostic can be
manually cleared but will reoccur every month
real time (720 hours on real time clock) as long
as the oil filter life remaining does not rise
above 20% (through normal calculations or
reinitializing) (Prior to RTUD Release in Fall of
09): Diagnostic occurs only when “service
messages” are enabled and when average oil
pressure drop exceeds 18%. Diagnostic can be
manually cleared but will reoccur every month
(720 hours on real time clock) as long as
average pressure drop does not fall below 16%.
