Record Data
The
Record Data
function is used to record vehicle Parameter Identification Data (PIDs)
while the vehicle is parked or being driven. This function is mainly used for diagnosing
intermittent driveability problems that cannot be diagnosed by any other method. For
example, if your vehicle sometimes loses power while going up steep hills, then you
should start a recording as soon as your vehicle reaches the base of the hill. The OBD II
System Tester records the supported PIDs in Frames at various time intervals. The first
5 Frames are recorded prior to the start time (0.0 seconds) Once started, Frames will
be recorded for 8 to 35 seconds; the number of Frames depends on the vehicles data
rate and quantity of PIDs. The
Record Data
function allows you to diagnose an intermit-
tent problem by analyzing data leading up to the problem, during the problem, and
possibly after the problem, depending on problem duration. The PIDs covered by the
OBD II System Tester are defined in
Appendix B.
