Toyota RAV4 Service Manual: Freeze frame data
- Freeze frame data
Hint:
- 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 on since the last time the abs was activated. However, if the vehicle was stationary or running at a low speed (7 km/h [4.3 Mph] or less), or if a dtc is detected, the skid control ecu stops counting.
- 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.
- Connect the intelligent tester (with can vim) to the dlc3.
- Turn the ignition switch on.
- Turn the tester on.
- From the display on the tester, select "freeze frame data".
