BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS ANTI-LOCK BRAKE SYSTEM FREEZE FRAME DATA
FREEZE FRAME DATA
Whenever an ABS DTC is detected, the skid control ECU (brake actuator assembly) stores the current vehicle (ECU or sensor) state as Freeze Frame Data.
The skid control ECU (brake actuator assembly) 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.
- HINT:
- ·
If the vehicle is stopped or driven at a low speed (7 km/h (4.3 mph) or less), or if a DTC is detected, the skid control ECU (brake actuator assembly) will stop counting the number.
·Freeze Frame Data at the time the ABS operates:
The skid control ECU (brake actuator assembly) stores and updates data whenever the ABS operates.
When the ECU stores data at the time a DTC is detected, the data stored during ABS operation is cleared.
·Freeze Frame Data at the time a DTC is detected:
When the skid control ECU (brake actuator assembly) stores data at the time a DTC is detected, no updates will be performed until the data is cleared.
