After making a selection, press
ENTER
to establish a communication link. Mul-
tiple PIDs may be sent if the vehicle is equipped with more than one computer
module — Powertrain Control Module (PCM), Transmission Control Module
(TCM), etc. The scan tool identifies them by their identification names (ID)
assigned by the manufacturer (i.e. $40 or $1F).
If the Scan Tool receives multiple
responses for a PID, such as MIL STA-
TUS, it displays the PID and with the
computer module ID blinking in paren-
theses.
If one or more control modules stops
responding, the tool displays a mes-
sage that it is not responding.
If you choose to continue, dashes will
replace the data in the right-hand col-
umn. If NO is selected, then the scan
tool attempts to reestablish communi-
cation with that module.

VIEW FREEZE DATA
When an emission-related fault occurs, certain vehicle conditions are recorded
by the on-board computer. This information is referred to as a Freeze Frame
data. The information is a “snapshot” of the operating conditions at the time of
a fault. This data can be overwritten by faults with a higher priority.
✓
If codes were erased, then freeze frame data may not be stored in vehicle
memory.
Select View Freeze Data from the
OBDII Function List and press
ENTER
.
The scan tool links to the vehicle, veri-
fies the PIDs and displays the data. Use
the
UP/DOWN
arrow keys to move
through the list.
If more than one computer module
responds with freeze frame data, then
the frame number and module display
on the first line. Press the
LEFT/RIGHT
key to change modules.
When done, press the
BACK
key to
return to the OBDII Function List.
