the average engine voltage demand.
Default = 15
28.5 If the difference between CAVG and EAVG reference numbers is greater than
the HI FROM ENGINE threshold, a diagnostic warning for that cylinder will
occur. This test will identify a cylinder whose voltage demand is too far above
the average engine voltage demand.
Default = 15
28.6 If the COV reference number is greater than the HI VARIATION COV threshold,
a diagnostic warning for that cylinder will occur. This test will identify a cylinder
whose cycle-to-cycle voltage demand has become erratic.
Default = 30
