12.3 If the CAVG reference number of a cylinder is above the HI SPARK VOLTAGE
threshold, a diagnostic warning for that cylinder will occur.
12.4 If the CAVG reference number of a cylinder is above the NO SECONDARY
SPARK threshold, a diagnostic warning for that cylinder will occur. This test
will identify cylinder firings that do not result in a spark — an open circuit
condition at the secondary of the coil resulting from a worn spark plug, or a
disconnected or failed secondary wire. To disable, set to 255.
12.5 If the difference between EAVG and CAVG reference numbers is greater than
the LO FROM ENGINE threshold, a diagnostic warning for that cylinder will
occur. This test will identify a cylinder whose voltage demand is too far below
the average engine voltage demand.
12.6 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.
