Freeze Frame Data [11/2022 - ]

WARNING: This page is about a different car, the 2025 Toyota Corolla Cross, 2024 Toyota Corolla Cross, and 2023 Toyota Corolla Cross. However, it is still accessible from the selected car via links, so may be relevant.
  1. FREEZE FRAME DATA 

    HINT: 

    • When a DTC is stored, the freeze frame data stores the current vehicle (sensor) state.
    • The freeze frame data cannot be cleared or updated until the recorded DTCs are cleared.
    1. Using the GTS, the state of the vehicle (sensors) when the system is operating or when a DTC was stored can be checked.
