The ECM illuminates the MIL and sets a DTC when either one of the following conditions, which could cause emission deterioration, is detected (2 trip detection logic)
- Within the first 1000 crankshaft revolutions of the engine starting, an excessive misfire count (approximately 20 to 50 misfires per 1000 crankshaft revolutions) occurs once
- After the first 1000 crankshaft revolutions, an excessive misfire count (approximately 20 to 60 misfires per 1000 crankshaft revolutions) occurs 4 times in sequential crankshaft revolutions
The ECM flashes the MIL and sets a DTC when either one of the following conditions, which could cause the three-way catalytic converter damage, is detected (2 trip detection logic)
- In every 200 crankshaft revolutions at a high engine rpm, the threshold misfire percentage is recorded once.
- In every 200 crankshaft revolutions at a normal engine rpm, the threshold misfire percentage is recorded 3 times.
