The Scan Tool is a special tool that communicates with the vehicle's 
computer. 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.  
In effect the Scan Tool lets you view, in "real time", 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 and release the LD 
button. 
2.
  A “One moment please . . .” message 
displays while the Scan Tool establishes 
communication with the vehicle. 
„
 
If the Scan Tool fails to establish 
communication with the vehicle, a 
“Communication Error” message is 
shown on the Scan Tool’s display. 
- Ensure your vehicle is OBD2 
compliant. See VEHICLES 
COVERED on page 5 for vehicle 
compliance verification information. 
-  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 the ENTER 
 button  to 
continue.
