Freeze Frame data is always associated with the "Priority
Code" (identified as Code #1 in the Code Reader's display).
If the FREEZE FRAME icon is lit when the "Priority Code"
(Code #1) is displayed on the Code Reader's screen, it
indicates that there is Freeze Frame data associated with
this code, and the vehicle's computer has saved it in its
memory.
8. To prolong battery life, Code Reader automatically turns "Off"
approximately one minute after it is disconnected from the vehicle.
Retrieved codes remain in Code Reader's memory, and may be
viewed at any time by turning the unit "On." If Code Reader's
batteries are removed, or if Code Reader is re-linked to a
vehicle to retrieve codes, any codes currently in its memory
are automatically cleared.
Refer to page 45 for Diagnostic Trouble Code definitions. Match the
retrieved DTC(s) with those listed. Read the associated definition(s),
and see the vehicle's service manual for further evaluation.
ERASING DIAGNOSTIC TROUBLE CODES (DTCs)
When Code Reader's ERASE function is used to erase
the DTCs from the vehicle's on-board computer,
"Freeze Frame" data and manufacturer-specific
enhanced data are also erased.
If you plan to take the vehicle to a Service Center for repair, DO NOT
erase the codes from the vehicle's computer. If the codes are erased,
valuable information that might help the technician troubleshoot the
problem will also be erased.
Erase DTCs from the computer's memory as follows:
When DTCs are erased from the vehicle's computer
memory, the I/M Readiness Monitor Status program resets
status of all the Monitors to a not run "flashing" condition. To
set all of the Monitors to a DONE status, an OBD 2 Drive
Cycle must be performed. Refer to your vehicle's service
manual for information on how to perform an OBD 2 Drive
Cycle for the vehicle under test.
