5.1 I/M Monitors (Emissions)
The I/M Monitors (Inspection / Maintenance) function is
used to view a snapshot of the operations for the emis-
sion system on OBDII vehicles. I/M Monitors is a very
useful function. To guarantee no faults exist make sure
all monitors are ok or n/a and no DTCs exist. Refer to the
vehicles service manual for the drive cycle operation.
During normal driving conditions, the vehicle computer
scans the emission system. After a specific amount of
drive time (each monitor has specific driving conditions
and time required), the computer monitors decide if the
vehicles emission system is working correctly or not as
well as detecting out of range values. When the monitor
status is:
• ok - vehicle was driven enough to complete the
monitor.
• inc (Incomplete) - vehicle was not driven enough to
complete the monitor.
• n/a (not applicable)- vehicle does not support that
monitor.
Depending on vehicle, disconnecting or a discharged
battery may erase DTCs and clear monitor status. Moni-
tors may be reset by:
• Erasing codes
• Vehicle control modules losing power
The I/M Monitors function can be run key on engine
running (KOER) or key on engine off (KOEO).
Extreme weather and/or road conditions can prevent a
monitor from running. Also, some monitors may require
a cold start to complete.
From the Global OBDII Functions Menu.
