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".

Front airbag sensor lh circuit malfunction
Description
The front airbag sensor lh consists of the diagnostic circuit, the frontal
deceleration sensor, etc.
If the center airbag sensor receives signals from the frontal deceleration
sensor, it determines whether or
not the srs should be activated.

Eps warning light circuit
Description
If the power steering ecu detects a malfunction, the p/s warning light comes
on. At this time, the power
steering ecu stores a dtc in its memory.
