FREEZE FRAME DATA
Tech Tips
If a DTC is output, the freeze frame data is recorded when the DTC occurs.
If freeze frame data is recorded when a DTC occurs, the freeze frame data is not cleared or updated until the recorded DTC is cleared.
Using the GTS, the condition of the vehicle (sensors) when the system is operating or when the malfunction DTC was recorded can be checked.
