FREEZE FRAME DATA
1. FREEZE FRAME DATA
HINT:
W
henever 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 stopped or at low speed
(4.3 mph (7 km/h) or less), or if a DTC is detected, the skid control ECU will not count the number after
that.
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 will be performed until the data is cleared.
