View Data
The View Data function allows you to view the vehicle’s Parameter Identifica-
tion (PID) data in real time. As the computer monitors the vehicle, the informa-
tion is simultaneously transmitted to the scan tool. Apart from
Read Codes ,
View Data is the most useful diagnostic function for isolating the cause of a vehi-
cle operation problem. Viewing data is also used for observing sensor data and
the status of switches, solenoids, and relays.
