Freeze Frame Data [12/2022 - ]

2025 Toyota Prius XLE AWDSECTION Freeze Frame Data [12/2022 - ]
  1. FREEZE FRAME DATA 
    NOTE:
    • It is difficult to show the specified values (judgment values) clearly because freeze frame data values change significantly due to differences in measurement conditions, surroundings, or vehicle conditions. For this reason, there may be a problem even when the values are within specification.
    • Turn the ignition switch to ON and park the vehicle on level ground. Check the freeze frame data by using the GTS.
    1. Turn the ignition switch off.
    2. Connect the GTS to the DLC3.
    3. Turn the ignition switch to ON.
    4. Turn the GTS on.
    5. Check the freeze frame data on the GTS.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
