Freeze Frame Data

FREEZE FRAME DATA

Whenever a DTC is detected or the ABS operates, the skid control ECU stores the current vehicle (sensor) status 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 (IG) since the last time the ABS was activated.
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 skid control ECU stores data at the time a DTC is detected, the data stored during ABS operation 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.
Connect Techstream to the DLC3.
Turn the ignition switch on (IG).
Select "Trouble Codes" on the tester display.

On the trouble code data display screen, select the DTC data display with Freeze Frame Data.
