Freeze Frame Data

HINT: 

• Whenever a DTC is stored or the brake system operates, 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 brake system was activated. However, if the vehicle was stationary or running at a low speed (7 km/h [4.3 mph] or less), or if a DTC is stored, the skid control ECU stops counting.
• Freeze frame data at the time the brake system operates:

  The skid control ECU stores and updates the data whenever the brake system operates.

  When the ECU stores data at the time a DTC is stored, the data stored when the brake system operated is cleared.

• Freeze frame data at the time a DTC is stored:

  When the skid control ECU stores data at the time a DTC is stored, no updates will be performed until the data is cleared.

1. Turn the ignition switch off and connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. From the display on the Techstream, select the Freeze Frame Data.
