Record Data
✓The Record Data function records vehicle PIDs while the vehicle
is parked or being driven. This function is mainly used for
diagnosing intermittent driveability problems that cannot be
isolated by any other method. The Scan Tool records data based
on time (5 frames prior to the start of the recording, and for a
duration after). The time after depends on the vehicle data rate.
The Record Data function allows diagnosis of an intermittent
problem by analyzing data leading up to the problem, during the
problem, and possibly after the problem, depending on duration.
From the Datastream Menu:
1.Select Record Data.
