3.4 MIL Status
The MIL (Malfunction Indicator Lamp) Status function displays the
state of the computer module that commanded the MIL to turn on. A
request is sent to the computer module(s) to state whether they are
commanding the MIL to turn ON. If the MIL Status is ON and the MIL
is not illuminated with the engine running, then a problem exists in the
MIL circuit. Refer to “Diagnostic Circuit Check” in the service repair
manual.
Some manufacturers will turn the MIL Off if a certain number of
drive cycles occur without the same fault being detected. The
DTCs related to a MIL are erased from the computer’s memory
after 40 warm-up cycles if the same fault is not detected.
Select the MIL Status function and
press the ENTER key.
The MIL Status will display on the
top line and a scrolling message on
the bottom indicating if the MIL lamp
should be ON or OFF.
When done, press the BACK key to return to the Main Men

3.5 I/M Monitors
The I/M (Inspection and Maintenance) Monitors function displays the
state of the vehicle’s OBD II Monitors. Monitors test the operation of
emission related systems or components and detect out-of-range
values. The vehicle may have to be operated under certain driving
conditions to initiate a monitor.
