Diagnostic Menu
The first time the scan tool links to the vehicle, the
communication protocol is automatically detected, and
is used until the scan tool is turned off or another vehi-
cle is diagnosed.
If an error message displays, make sure the DLC cable is
attached and the ignition key is on. Cycle ignition key to OFF
for 10 seconds, then ON. This may be required to reset
computer. If required, select YES to try again. If problem still
exists, refer to “Error Messages” in Troubleshooting.
The scan tool keeps all data received from the last vehi-
cle selected until any of the following occurs:
•
A new vehicle is selected.
•
Scan tool is flash programmed to update software.
On initial link to vehicle, scan tool checks the status of
I/M Monitors no matter which function is selected.

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 DTC’s 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.
