CODE RETRIEVAL PROCEDURE
■
If the Tool fails to link to the vehicle’s
computer, a “Vehicle is not respond-
ing” message shows on the Tool’s
LCD display. Do the following:
- Verify the ignition is ON.
- Check the cable connections at
the Tool and at the vehicle’s DLC.
- Turn the ignition OFF, wait 10-12 seconds, then turn back ON
to reset the computer.
- Press the ENTER/FF
button and repeat steps 4 through
6 as necessary.
7. If the Tool was able to link to the vehicle
successfully a "Code retrieval was suc-
cessful..." message shows temporarily
on the Tool’s LCD display followed by
any retrieved DTCs.
■
The Tool will display a code only if
codes are present in the vehicle's
computer memory. If no codes are
present, a "No DTC's are presently
stored in the vehicle's computer"
message is displayed.
8. If more than one code was retrieved
press the DTC SCROLL
button, as
necessary, to display additional codes
one at a time.
In the case of long code definitions, a small arrow is shown
in the upper/lower right-hand corner of the code display area
to indicate the presence of additional information. Use the
and
buttons, as necessary, to view the additional
information.
9. Disconnect the Tool from the vehicle and turn the ignition key OFF.
10. To prolong battery life, the Tool automatically shuts "Off" after
approximately three minutes of no button activity. The DTCs
retrieved will remain in the Tool's memory, and may be viewed at
any time. If the Tool’s batteries are removed, or if the Tool is re-
linked to a vehicle to retrieve codes, any prior codes in its memory
are automatically cleared.
