ANTI-LOCK BRAKE SYSTEM FREEZE FRAME DATA


  1. FREEZE FRAME DATA


    1. Whenever a DTC is stored, the skid control ECU (brake actuator assembly) stores the current vehicle state as freeze frame data.

    2. The skid control ECU (brake actuator assembly) 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.

      Tech Tips


      • If the vehicle is stopped or at a low speed (7 km/ h (4 mph) or less), or if a DTC is stored, the skid control ECU (brake actuator assembly) stops 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 (brake actuator assembly) stores and updates data whenever the ABS operates. When the ECU stores data at the time a DTC is stored, the data stored during ABS operation is cleared.

      • Freeze frame data at the time a DTC is stored: When the skid control ECU (brake actuator assembly) stores data at the time a DTC is stored, no updates are performed until the data is cleared.

  2. CHECK FREEZE FRAME DATA


    1. Turn the ignition switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON.

    4. Enter the following menus: Chassis / ABS/VSC/TRC / Trouble Codes.

    5. According to the display on the GTS, select the trouble code data display with freeze frame data.

  3. CLEAR FREEZE FRAME DATA

    Note

    Clearing the DTC also clears the freeze frame data.
