Freeze Frame Data

BRAKE CONTROL: ELECTRONICALLY CONTROLLED BRAKE SYSTEM: FREEZE FRAME DATA

1. FREEZE FRAME DATA

(a) If a DTC is detected when the ABS, BA, TR(A)C or VSC 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 engine switch has been turned from off to on (IG) since the last time the ABS, BA, TR(A)C or VSC was activated.

HINT
* The skid control ECU will not count the number of times the engine switch is turned on (IG) if the vehicle does not drive at the speed of at least 7 km/h (4.3 mph), or a DTC is detected.
* Freeze frame data at the time the ABS, BA, TR(A)C or VSC operates:
The skid control ECU stores and updates the data whenever the ABS, BA, TR(A)C or VSC system operates.
When the ECU stores data at the time a DTC is detected, the data stored when the ABS, BA, TR(A)C or VSC operated may be 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.

(b) Connect the Techstream to the DLC3.

(c) Turn the engine switch on (IG).
