Freeze Frame Data

FREEZE FRAME DATA
1. Whenever an ABS and/or VSC DTC is detected, the skid control ECU stores the current vehicle (sensor) state as Freeze Frame Data
2. The skid control ECU 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, 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 engine switch had been turned from off to on (IG).
  - 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 engine switch on (IG)
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.
1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG)
3. Clear the DTCs and Freeze Frame Data (See DTC CHECK / CLEAR )
