CODE RETRIEVAL PROCEDURE<br />
� The Tool will display a code only if<br />
codes are present in the vehicle's<br />
computer memory. If no codes are<br />
present, a "No DTC's are presently<br />
stored in the vehicle's computer"<br />
message is displayed.<br />
9. If more than one code was retrieved<br />
press the DTC/FF button, as<br />
necessary, to display additional codes<br />
one at a time.<br />
In the case of long code definitions, a small arrow is shown in<br />
the upper/lower right-hand corner of the code display area to<br />
indicate the presence of additional information. Use the<br />
and buttons, as necessary, to view the additional<br />
information.<br />
10. Disconnect the Tool from the vehicle and turn the ignition key OFF.<br />
11. To prolong battery life, the Tool automatically shuts "Off" after<br />
approximately three minutes of no button activity. The DTCs<br />
retrieved will remain in the Tool's memory, and may be viewed at<br />
any time. If the Tool’s batteries are removed, or if the Tool is relinked<br />
to a vehicle to retrieve codes, any prior codes in its memory<br />
are automatically cleared.<br />
12. Follow the testing and repair procedures outlined in the vehicle's<br />
service repair manual to correct "hard" DTCs. Codes should be<br />
addressed and eliminated in the order they were received, erasing<br />
(see SERVICING DTCs - OBD I on page 97) and retesting after<br />
each repair is made to be sure the fault was eliminated.<br />
The green, yellow and red LEDs are used (with the LCD<br />
display) as visual aids to make it easier to determine engine<br />
system conditions. See SERVICING DTCs - OBD I on page<br />
97 for information on interpreting LEDs and servicing DTCs.<br />
