Toyota C-HR + G13 + CB004 = Triangle Error OEM Backup Camea in Reverse Gear


  • Hello,

    G13 does not want to switch on the Backup Camera when in Reverse Gear.

    I have just the black screen with Triangle Error in the middle.

    What i have checked so far:

    1. Camera works in F-Cam app

    2. Canbus is set to 8

    3. "Prohibit reverse" settings is not there in the "Other" Sub-Menu

    What else can i try?



  • F-Cam test:

    Reverse Gear error:

    Canbus Settings:

    Other Sub-Menu Settings - no "Prohibit reverse":

    One other thing, the written manual is confusing, showing some Vires that dont event exist:

    I dont have that "BACK" wire, and dont think that i need it.
    The OEM Backup Camera gets power when tested in F-Cam app, but does not start (Power???) when putting the car in Reverse Gear.

  • I have updated the firmware to: 20250421
    MCU updated to: 4.16a

    No changes, the Camera does not start in Reverse Gear, only in F-Cam app.


  • It must be a software issue - on my old PX6 unit everything works fine.
    I tried the CB004 from my old PX6 unit on G13 - Camera still wont start.
    PX6, plug-and-play, works fine.
