After selecting View Freeze Data, the OBD II
System Tester establishes a communication
link to the vehicles PCM. All PIDs supported by
the vehicle are displayed. Use the UP and

lected data parameters.
When done, press the BACK key to return to the OBD II Function Menu.
If no data exists, a message will display
prompting the user to press any key to return to
the OBD II Function Menu.
NOTE: If you get an Operating Error message, make sure the DLC adapter cable is
securely attached and the ignition key is ON, then try again. If the problem
remains, refer to Section 4: On-Line Help and Trouble-Shooting Tips.
Record Data
The Record Data function is used to record vehicle Parameter Identification Data (PIDs)
while the vehicle is parked or being driven. This function is mainly used for diagnosing
intermittent driveability problems that cannot be diagnosed by any other method. For
example, if your vehicle sometimes loses power while going up steep hills, then you
should start a recording as soon as your vehicle reaches the base of the hill. The OBD II
System Tester records the supported PIDs in Frames at various time intervals. The first
5 Frames are recorded prior to the start time (0.0 seconds) Once started, Frames will
be recorded for 8 to 35 seconds; the number of Frames depends on the vehicles data
rate and quantity of PIDs. The Record Data function allows you to diagnose an intermit-
tent problem by analyzing data leading up to the problem, during the problem, and
possibly after the problem, depending on problem duration. The PIDs covered by the
OBD II System Tester are defined in Appendix B.
Select Record Data from the OBD II Function Menu and press the ENTER key. The
Pick Trigger Method menu is displayed next. Select either Manual Trigger or Trigger
on Codes then press the ENTER key.
If the memory is full from a previous recording,
it must be erased before recording more data.
To erase memory and continue, select YES
and press the ENTER key and then the Pick
Trigger Method options will display. Otherwise,
select NO and press the ENTER key to return
to the OBD II Function Menu.
NOTE: If you get an Operating Error message, make sure the DLC cable is securely
attached, and the ignition key is ON, then try again. If the problem persists,
refer to Section 4 of this Manual: On-Line Help and Trouble-Shooting Tips.
