Misfire Current Cyl. #1-#8

Range (Current Counts):
The scan tool displays the number of misfires detected during each 200 crankshaft revolution sampling period. Each cylinder has its own register to record misfires that have occurred. If the Misfire Current Cyl is incrementing, it will be reset to zero after 200 crankshaft revolutions. If the misfire DTC has set, the number of misfires in the register will be added to the Misfire History cyl register each time the current cyl. register is reset to zero.

Range (Counts):
The scan tool displays a record of misfires that have occurred since the misfire DTC was set. This parameter will be summed with the current cylinder register each time the 200 crankshaft revolution sample is reset to zero if the current misfire test block exceeds an allowable misfire threshold.
