Toyota Yaris XP210 (2020-2024) Reapir and Service Manual / Drivetrain / Gf1a (transfer / 4wd / Awd) / Active Torque Split Awd System / Freeze Frame Data

FREEZE FRAME DATA

FREEZE FRAME DATA

(a) When a DTC is stored, the AWD ECU assembly stores the current vehicle state as Freeze Frame Data.

HINT:

Freeze Frame Data at the time a DTC is stored:

When the AWD 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

(a) According to the display on the GTS, select the trouble code data display with Freeze Frame Data.
