Ford arranges the PIDs in six groups:
❒ Standard Info: viewing of analog
sensor signals, such as measured
voltage from O2 sensors, temper-
ature sensors, and air flow sen-
sors.
❒ O2 Sensor Info: viewing oxygen sensor information.
❒ Misfire Info: viewing of cylinder misfire information.
❒ Auto Trans Info: viewing of automatic transmission information.
❒ Man Trans Info: viewing of manual transmission information.
❒ A/C Info: viewing of air conditioning information.
After selecting a group, the scan tool
asks the vehicle to provide the PIDs it
supports for that group.
The scan tool displays a menu with dis-
play options. Use the
to
select an option and press
.
Refer to “Viewing Data” on page 3-9 to
setup the data list.
After making a selection, press
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 modules stops responding, the scan tool displays a message that
the module is not responding and asks to continue without it. If No is selected,
the Scan Tool attempts to reestablish communication with that module.
If one or more control modules stops
responding, the tool will display a mes-
sage that it is not responding. If you
choose to continue, dashes will replace
the module ID.
