Freeze Frame Data
WARNING: This page is about a different car, the 2011 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
- FREEZE FRAME DATA
- Whenever an ABS DTC is detected, the skid control ECU stores the current vehicle (sensor) state as Freeze Frame Data.
- The skid control ECU stores the number of times (maximum: 31) the ignition switch has been turned from off to on (IG) since the last time the ABS was activated.
HINT:
- If the vehicle is stopped or at a low speed (7 km/ h (4.3 mph) or less), or if a DTC is detected, the skid control ECU will stop counting the number.
- Freeze Frame Data at the time the ABS operates:
The skid control ECU stores and updates data whenever the ABS system operates. When the ECU stores data at the time a DTC is detected, the data stored during ABS operation is cleared.
- Freeze Frame Data at the time a DTC is detected:
When the skid control ECU stores data at the time a DTC is detected, no updates will be performed until the data is cleared.
- CHECK FREEZE FRAME DATA
- Connect the Techstream to the DLC3.
- Turn the ignition switch on (IG).
- Turn the Techstream on.
- On the Techstream display, select the Freeze Frame Data.ABS/VSC/TRAC

- CLEAR FREEZE FRAME DATA NOTE:
Clearing the DTCs will also clear the Freeze Frame Data.
- Connect the Techstream to the DLC3.
- Turn the ignition switch on (IG).
- Clear the DTCs and Freeze Frame Data. Refer to DTC CHECK / CLEAR .
