NOTE:
Freeze Frame (Powertrain DTC A/B Type)
Freeze Frame is an element of the Diagnostic Manage-
ment System which stores various vehicle information at
the moment an emissions-related fault is stored in
memory and when the MIL is commanded on. These data
can help to identify the cause of a fault. Refer to
Storing
And Erasing Freeze Frame Data for more detailed in-
formation.
Failure Records (Powertrain DTC C/D Type)
Failure Records data is an enhancement of the OBD II
Freeze Frame feature. Failure Records store the same
vehicle information as does Freeze Frame, but it will store
that information for any fault which is stored in on-board
memory, while Freeze Frame stores information only for
emission-related faults that command the MIL on.
