Malfunction Indicator Lamp (MIL):

When the vehicle on board computer detects a problem in the emission related systems or components, its diagnostic program will assign a fault code (DTC) and store it in its memory. It also records a “Freeze Frame” of the conditions present when the fault was found and set the malfunction indicator lamp (MIL) alight. Some faults require detection

for two trips in a row before the MIL is turned on.

Three typical examples of MIL are shown below:

Definition of Trip

‘A Trip’ is define as a Key-ON, Key-OFF event in which the powertrain control

module (PCM) detects the following:

o

 

• Engine coolant temperature should exceed 70 C

o

Engine coolant temperature should change more than 20 C after starting the engine.

Engine speed should go over 400 RPM.

st

When the powertain control module (PCM) detects a fault during the 1 trip, the DTC and the corresponding ‘Freeze Frame’ data are stored in the PCM’snd memory. The MIL will not light up until the fault is again detected during the 2 trip. Certain DTCs are

capable of turning the MIL on or blinking during the first trip.
