Freeze Frame Data
- FREEZE FRAME DATA
- Whenever a DTC is detected or the ABS 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 is turned from off to ON since the last time the ABS was activated.
HINT:
- If the vehicle is stopped or driving at a low speed (7 km/h (4.3 mph) or less), or if a DTC is detected, the skid control ECU stops counting the number of ignition switch operations.
- 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 when the ABS operated is erased.
- 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.
- Connect Techstream to the DLC3.
- Turn the ignition switch to ON.
- On the tester display, select the freeze frame data.
