✓Datastream Menu functions are used to view and record engine
data transmitted from the vehicle on EEC-IV vehicles beginning
in 1990. These functions allow viewing of data parameters in real
time to pinpoint problems when they occur. The Scan Tool also has
the ability to record these data parameters as the vehicle is
operated to locate intermittent problems.
View Data
✓The View Data function allows the mechanic to view Parameter
Identification Numbers (PIDs) in real time. Simply stated, as the
powertrain control module (PCM) monitors the vehicle’s PIDs,
they are simultaneously transmitted to the Scan Tool. Viewing data
is also used for observing sensor data and the on/off state of
switches, solenoids, and relays.
