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".

Can bus line
Description
When any dtc for the can communication system is output, first measure the
resistance between the
terminals of the dlc3 to specify the trouble area, and check that there is not a
short in the can main wire,
between the main wire, to +b, or to gnd.
