(1) DTC requires 2 consecutive drive cycles to set MIL.
(2) If misfire is sufficient enough to cause catalyst damage, Malfunction Indicator Light (MIL) should flash. If misfire is not sufficient enough to cause catalyst damage, DTC requires 2 consecutive drive cycles to set MIL
(3) See appropriate DIAGNOSIS article in AUTOMATIC TRANSMISSIONS.
