ANTI-LOCK BRAKE SYSTEM FREEZE FRAME DATA

  1. FREEZE FRAME DATA

    1. Whenever a DTC is detected, the skid control ECU (brake actuator assembly) stores the current vehicle (sensor) 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.

      Tip:

      • However, 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 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 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.

  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. Turn the GTS on.

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

      Chassis > ABS/VSC/TRC > Trouble Codes

    6. Select a DTC to display its Freeze Frame Data.

  3. CLEAR FREEZE FRAME DATA

    Note:

    Clearing the DTC will also clear the Freeze Frame Data.

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Clear the DTC and Freeze Frame Data.
