Recording Data
The
Recorder Data
function is used to record PIDs to help diagnose intermittent
drivability problems that can not be determined by any other method.
A recording consists of 5 frames of data before trigger point and several frames
after trigger.
√ There are 2 types of trigger methods used:
• Manual Trigger – triggers recording whenever the operator presses the
ENTER
key.
• Trigger On DTCs - automatically triggers recording when a code is
detected by vehicle.
√ Trigger On DTCs is not available on all vehicles.
√ Some vehicle need to be driven for a long period of time to store a code
after a drivability fault occurs. If Trigger On DTCs is selected to make a
recording, there might not be drastic change in the data before and after
trigger.
Do not operate the code reader while driving; always have two
persons in vehicle when recording – one to drive and the other
to operate the code reader.
