FREEZE FRAME DATA
FREEZE FRAME DATA
(a) When a DTC is stored, the 4WD ECU assembly stores the current vehicle state as Freeze Frame Data.
HINT:
Freeze Frame Data at the time a DTC is stored:
- When the 4WD ECU assembly stores data at the time a DTC is stored, no updates will be performed until the data is cleared.
- "Number of IG ON" is not stored as Freeze Frame Data.
CHECK FREEZE FRAME DATA
