Freeze Frame Data [11/2023 - ]

  1. FREEZE FRAME DATA 
    1. Whenever a lighting system (w/ AFS) DTC is stored, the headlight ECU sub-assembly and forward recognition camera stores the current vehicle state as freeze frame data.
  2. CHECK FREEZE FRAME DATA 
    1. Enter the following menus:
      1. Body Electrical / Headlight Control / Trouble Codes.

        Body Electrical > Headlight Control > Trouble Codes 

      2. Body Electrical / Headlight Control (Sub) / Trouble Codes.
