If an Error message is shown on the
Code Reader’s LCD display, it
indicates there is a communication
problem. This means that the Code
Reader is unable to communicate
with the vehicle's computer. Do the
following:
- Turn the ignition key off, wait 5 seconds and turn the key
back on to reset the computer. Press the LINK

determine engine system conditions.
Green LED - Indicates that all

PENDING CODE PRESENT - If the
yellow LED is lit, it may indicate the
existence of a pending code. Check
the Code Reader’s LCD display for

no pending code is shown, the yellow
LED indicates Monitor Status (see the
following).
MONITOR STATUS - If the Code
Reader’s LCD display shows a zero
(indicating there are no DTCs present
in the vehicle's computer), but the
yellow LED is lit, it indicates a
"Monitor Has Not Run" status. This
means that some of the Monitors on
the vehicle have not yet finished their
diagnostic self-testing. This condition
is confirmed by one or more blinking
