Freeze Frame Data
- 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 since the last time the ABS was activated.
HINT:
- If the vehicle is stopped, 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 of times the ignition switch has been turned from off to ON.
- 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 to ON.
- Turn the Techstream on.
- Enter the following menus: Chassis / ABS/VSC/ TRAC / Trouble Codes.
- According to the Techstream display, select the trouble code data display with Freeze Frame Data.

- 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 to ON.
- Clear the DTCs and Freeze Frame Data (See DTC CHECK / CLEAR ).
