FREEZE FRAME DATA

(a)

The vehicle (sensor) status at the occurrence of abnormality of the diagnosis code and during the ABS
operation can be memorized and displayed using the hand-held tester.

(b)

Only one record of freeze frame data is stored, however, freeze frame data during the ABS operating
is always up-dated. After the storage of freeze frame data, up to 31 ignition ”ON” operations are stored
and displayed.

HINT:
If the ignition switch ”ON” operation exceeds 31 times, ”31” appears on the display.
(c)

If the diagnosis code abnormality occurs, the freeze frame data at the occurrence of the abnormality
is stored but the ABS actuation data is deleted.
