Freeze Frame Data [09/2014 - 10/2015]
- FREEZE FRAME DATA
- Whenever an ABS DTC is detected, the skid control ECU (brake actuator assembly) stores the current vehicle (sensor) state as Freeze Frame Data.
- The skid control ECU (brake actuator assembly) stores the number of times (maximum: 31) the engine 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 (brake actuator assembly) will stop counting the number.
- Freeze Frame Data at the time the ABS operates:
The skid control ECU (brake actuator assembly) 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 (brake actuator assembly) 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 engine switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Chassis / ABS/VSC/TRAC / Trouble Codes.
- According to the display on the Techstream, select the trouble code data display with 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 engine switch on (IG).
- Clear the DTCs and Freeze Frame Data (Refer to DTC CHECK / CLEAR [09/2014 - 10/2015] ).
