Freeze Frame Data

BRAKE CONTROL: ELECTRONICALLY CONTROLLED BRAKE SYSTEM: FREEZE FRAME DATA

1. FREEZE FRAME DATA/INFORMATION

(a) Whenever an ABS, VSC or electronically controlled brake system DTC is detected, the skid control ECU stores the current vehicle (sensor) state as Freeze Frame Data.

(b) 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.

HINT
If the vehicle is stopped or moving 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 of times the ignition switch has been turned from off to ON.

(c) For DTCs stored in the skid control ECU, information (INF) codes that are contained in the Freeze Frame Data can be displayed on the Techstream.

HINT
* 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 cleared.
* 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.
