Freeze Frame Data [07/2020 - ]
WARNING: This page is about a different car, the 2022 Toyota Prius and 2021 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.
- DESCRIPTION
- Whenever a front radar sensor system DTC is stored, the millimeter wave radar sensor assembly stores the current vehicle state as Freeze Frame Data.
- CHECK FREEZE FRAME DATA
- Select a DTC to display the freeze frame data.
Body Electrical > Front Radar Sensor > Trouble Codes
