ABS (Antilock Brake System) (for Sedan)








BRAKE CONTROL: ANTI-LOCK BRAKE SYSTEM (for Sedan): FREEZE FRAME DATA

FREEZE FRAME DATA

1. FREEZE FRAME DATA
HINT:
- 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 has been turned from OFF to ON since the last time the ABS was activated. However, if the vehicle was stationary or running at a low speed (4.3 mph [7 km/h] or less), or if a DTC is detected, the skid control ECU stops counting.
- Freeze frame data at the time the ABS operates:
The skid control ECU stores and updates the 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 are performed until the data is cleared.
