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