Non-Emission Related Freeze Frame Data
Freeze frame data allows access to non-emission related values from specific manufacturers PIDs. These values are stored when a non-emission related DTC is stored in continuous memory. This provides a snapshot of the conditions that were present when the DTC was stored. Once 1 set of freeze frame data is stored, this data remains in memory even if another DTC is stored. When a DTC associated with the freeze frame data is cleared or a KAM reset is carried out, new freeze frame data can be stored again.
