Freeze Frame Data [08/2019 - ]
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2022 Lexus RX 450hL, 2022 Lexus RX 450h, 2021 Lexus RX 450hL, 2021 Lexus RX 450h, and 2020 Lexus RX 450hL. 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
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Body Electrical / Front Radar Sensor / Trouble Codes.
Body Electrical > Front Radar Sensor > Trouble Codes
- According to the display on the Techstream, select a DTC with freeze frame data.
- Read the freeze frame data recorded when the DTC was stored.
