This option lets you view and capture (record) real-time Live Data. This data including current operating status for
parameters and/or sensor information can provide insight on overall vehicle performance. It can also be used to
guide vehicle repair.
*Notes:
 If you must drive the vehicle in order to perform a troubleshooting procedure, ALWAYS have a second person help you.
Trying to drive and operate the diagnostic tool at the same time is dangerous, and could cause a serious traffic accident.
 The real time (Live Data) vehicle operating information (values/status) that the on-board computer supplies to the tool for
each sensor, actuator, switch, etc. is called Parameter Identification Data (PID).
On the diagnostic function selection screen, tap Read Data Stream, the following screen will appear.
