Freeze Frame Data

WARNING: This page is about a different car, the 2012 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
  1. FREEZE FRAME DATA 
    NOTE:
    • Freeze frame data values will vary depending on the measurement conditions, surroundings, or vehicle conditions. For this reason, there may be a problem even if the values are within specifications.
    • Turn the ignition switch on (IG) and park the vehicle on level ground. Check the freeze frame data by using the Techstream.
    1. Turn the ignition switch off.
    2. Connect the Techstream to the DLC3.
    3. Turn the ignition switch on (IG).
    4. Turn the Techstream on.
    5. Check the freeze frame data on the Techstream.
