Body & Accessories Instrumentation/Driver Info
Freeze Frame Data
•
The FFD ( F reeze F rame D ata) represent the instrument cluster control status at the
occurrence of a fault. The instrument cluster can store the FFDs for up to four DTCs
(FFD1 to FFD4), with the most recent data being FFD1. This data will not be overwritten,
except that more than four DTCs are stored.

The FFD is very helpful to diagnose the potential causes of a malfunction, especially
