FREEZE FRAME DATA
Troubleshooting
| FREEZE FRAME DATA |
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 the ON position since the last time the ABS was activated.- HINT:
- However, if the vehicle is stopped or at low speed (4.3 mph (7 km/h) or less), or if a DTC is detected, the skid control ECU will stop counting the number since then.
- 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 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.
- However, if the vehicle is stopped or at low speed (4.3 mph (7 km/h) or less), or if a DTC is detected, the skid control ECU will stop counting the number since then.
Connect the intelligent tester to the DLC3.
Turn the ignition switch on.
From the display on the tester, select the FREEZE FRAME DATA.
