Freeze Frame Data [05/2023 - ]

WARNING: This page is about a different car, the 2024 Lexus LC 500. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FREEZE FRAME DATA
HINT:

The ECU records vehicle and driving condition information as freeze frame data the moment a DTC is stored.
1. Enter the following menus: Powertrain / Radar Cruise1*1 or Radar Cruise2*2 / Trouble Codes.
  1. *1: Output from the ECM
  2. *2: Output from the forward recognition camera
2. Select the DTCs (with snow icon) for which freeze frame data is recorded.
  Powertrain > Radar Cruise1 > Trouble Codes
  
  Powertrain > Radar Cruise2 > Trouble Codes
  
  NOTE:
  The operating conditions the moment a DTC is stored are recorded as freeze frame data. Furthermore, only the latest 3 DTCs can be stored by the forward recognition camera.
