CODE RETRIEVAL PROCEDURE<br />
7. If the CanOBD2&1 <strong>Scan</strong> <strong>Tool</strong> was able<br />
to link to the vehicle successfully a<br />
"Code retrieval was successful..."<br />
message shows temporarily on the<br />
CanOBD2&1 <strong>Scan</strong> <strong>Tool</strong>’s display<br />
followed by any retrieved DTCs.<br />
� The CanOBD2&1 <strong>Scan</strong> <strong>Tool</strong> will<br />
display a code only if codes are<br />
present in the vehicle's computer<br />
memory. If no codes are present, a<br />
"No DTCs are presently stored in<br />
the vehicle's computer" message is<br />
displayed.<br />
8. If more than one code was retrieved<br />
press the DTC SCROLL , 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 information.<br />
9. Disconnect the CanOBD2&1 <strong>Scan</strong> <strong>Tool</strong> from the vehicle and turn<br />
the ignition key OFF.<br />
10. To prolong battery life, the CanOBD2&1 <strong>Scan</strong> <strong>Tool</strong> automatically<br />
shuts "Off" after approximately three minutes with no button activity.<br />
The DTCs retrieved will remain in the CanOBD2&1 <strong>Scan</strong> <strong>Tool</strong>'s<br />
memory, and may be viewed at any time. If the CanOBD2&1 <strong>Scan</strong><br />
<strong>Tool</strong>’s batteries are removed, or if the CanOBD2&1 <strong>Scan</strong> <strong>Tool</strong> is relinked<br />
to a vehicle to retrieve codes, any prior codes in its memory<br />
are automatically cleared.<br />
� See VIEWING DTCs IN THE CANOBD2&1 SCAN TOOL’S<br />
MEMORY on page 13 to view DTCs stored in the CanOBD2&1<br />
<strong>Scan</strong> <strong>Tool</strong>’s memory.<br />
11. 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 ERASING DTCs (OBD I SYSTEMS) on page 112) and<br />
retesting after each repair is made to be sure the fault was<br />
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 />
110 for information on interpreting LEDs and servicing DTCs.<br />
