The Scan Tool lets you view and/or "capture" (record) "real-time" Live
Data. This information includes values (volts, rpm, temperature, speed
etc.) and system status information (open loop, closed loop, fuel system
status, etc.) generated by the various vehicle sensors, switches and
actuators. These are the same signal values generated by the sensors,
actuators, switches and/or vehicle system status information used by
the vehicle's computer when calculating and conducting system
adjustments and corrections.
The real time (Live Data) vehicle operating information (values/status)
that the computer supplies to the Scan Tool for each sensor, actuator,
switch, etc. is called Parameter Identification (PID) Data.
Each PID (sensor, actuator switch, status, etc.) has a set of operating
characteristics and features (parameters) that serve to identify it. The
Scan Tool displays this information for each sensor, actuator, switch or
status that is supported by the vehicle under test.
WARNING
: If the vehicle must be driven in order to perform a
troubleshooting procedure,
ALWAYS
have a second person
help you. One person should drive the vehicle while the other
person observes the Scan Tool data. Trying to drive and
operate the Scan Tool at the same time is dangerous, and
could cause a serious traffic accident.

1.
While linked to the vehicle, start the engine, then press
LD
.
2.

- Ensure your vehicle is OBD2
compliant.
- Verify the connection at the DLC,
and verify the ignition is ON.
- Turn the ignition OFF, wait 5
seconds, then back ON to reset
the computer.
- Press
ENTER
to continue.
3.
Real-time Live Data (PID) information supported by the vehicle
under test displays.
If Live Data is not supported by the vehicle under test, an
advisory message displays. Press
SYSTEM MENU
to return
to the System Menu. Live Data is not available for your vehicle.
The values for the various PIDS displayed may change as the
vehicle's operating conditions change.
4.
Only a limited amount of PID data can be displayed on the screen at
one time. If additional PID data is available, a small arrow is shown
on the display. Press
UP
and
DOWN
, as necessary, to view
all available PID data.
