Freeze Frame Data

HINT:

• When 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 has been turned from OFF to ON since the last time the ABS was activated. However, if the vehicle is stopped, the vehicle is driven at 7 km/h (4.3 mph) or less, or a DTC is detected, the ECU will not count the next time the ignition switch is turned from OFF to ON.
• Freeze frame data at the time the ABS operates: The skid control ECU stores data or updates stored data when the ABS operates. This data is erased when the ECU stores data at the time a DTC is detected.
• Freeze frame data at the time a DTC is detected: When the ECU stores data at the time a DTC is detected, the data will not be updated until the data is cleared.

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch ON.
3. From the display on the tester, select Freeze Frame Data.
