CODE RETRIEVAL PROCEDURE
7. If the CanOBD2&1 Scan Tool was able
to link to the vehicle successfully a
"Code retrieval was successful..." mes-
sage shows temporarily on the
CanOBD2&1 Scan Tool’s display fol-
lowed by any retrieved DTCs.
■ The CanOBD2&1 Scan Tool will dis-
play a code only if codes are present
in the vehicle's computer memory. If
no codes are present, a "No DTC' are
presently stored in the vehicle's com-
puter" message is displayed.
8. If more than one code was retrieved
press the DTC SCROLL , as nec-
essary, 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 CanOBD2&1 Scan Tool from the vehicle and turn
the ignition key OFF.
10. To prolong battery life, the CanOBD2&1 Scan Tool automatically
shuts "Off" after approximately three minutes with no button activi-
ty. The DTCs retrieved will remain in the CanOBD2&1 Scan Tool's
memory, and may be viewed at any time. If the CanOBD2&1 Scan
Tool’s batteries are removed, or if the CanOBD2&1 Scan Tool is re-
linked to a vehicle to retrieve codes, any prior codes in its memory
are automatically cleared.
■ See Viewing DTCs in the CanOBD2&1 Scan Tool’s Memory
on page 14 to view DTCs stored in the CanOBD2&1 Scan Tool’s
memory.
11. Follow the testing and repair procedures outlined in the vehicle's
service repair manual to correct "hard" DTCs. Codes should be
addressed and eliminated in the order they were received, erasing
(see Erasing DTC's on page 102) and retesting after each repair is
made to be sure the fault was eliminated.
The green, yellow and red LEDs are used (with the LCD dis-
play) as visual aids to make it easier to determine engine sys-
tem conditions. See Servicing Diagnostic Trouble Codes
on page 100 for information on interpreting LEDs and servic-
ing DTCs.
