Freeze Frame Data
- FREEZE FRAME DATA
- Whenever an ABS DTC is detected, 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 engine switch has been turned from off to on (IG) since the last time the ABS was activated.
HINT:
- 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 will stop counting the number.
- 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 during ABS operation 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.
- CHECK FREEZE FRAME DATA
- Connect the intelligent tester to the DLC3.
- Turn the engine switch on (IG).
- On the tester display, select the Freeze Frame Data.INTELLIGENT TESTER DISPLAY REFERENCE
