Troubleshooting
Control Panel Doesn't Appear
Symptoms: You enter an emergency vehicle but no UI shows up.
Possible causes:
Vehicle is not class 18
Check vehicles.meta must be VC_EMERGENCY
No config file for this vehicle
Create a config in the configs/ folder matching the spawn name
Config file has wrong spawn name
The backtick spawn name in the config must exactly match the vehicle's spawn name
Resource not started
Ensure controlPanelV3 is in your server.cfg
Sitting in wrong seat
Check Config.SeatPermissions , by default only driver (-1) and front passenger (0) are configured
Debug: Use /debugConfig while in the vehicle to print the model hash and loaded config to the F8 console.
No Siren Sound
Symptoms: The siren button toggles in the UI but no sound plays.
Possible causes:
BMT-Sirens not started
Ensure BMT-Sirens starts before controlPanelV3 in server.cfg
Audio bank not loaded
Check F8 console for audio bank errors
Invalid siren preset name
Verify the sirene value in your config matches a key in sirenes.lua
Siren set to 'geen'
This disables the siren intentionally
Sirens Not Syncing to Other Players
Symptoms: You hear the siren but other players don't.
Possible causes:
OneSync not enabled
StateBag sync requires OneSync
Players too far away
Sync range is 500 meters for sirens
Network ID issues
The vehicle may not have a valid network ID, try respawning it
Extras Don't Toggle
Symptoms: You press a button but no visual change on the vehicle.
Possible causes:
Wrong extra IDs in config
Use a trainer to manually check which extra numbers correspond to which visual elements
Extras don't exist on the model
The extra must be defined in the vehicle's model (ZModeler)
SetVehicleAutoRepairDisabled conflict
Another script may be interfering with vehicle extras
Horn Doesn't Work
Symptoms: Pressing the horn key does nothing or plays the default GTA horn.
Possible causes:
No horn handler for this siren type
Check Sirenes.HornHandler in sirenes.lua , every siren type needs a horn entry
switchWithHornKey confusion
With this enabled, a quick tap switches siren tone instead of honking. Hold longer for the horn.
Not in driver seat
Horn animation and control only works from the driver seat
UI Position Doesn't Save
Symptoms: You move the panel but it resets after reconnecting.
Possible causes:
KVP storage issue
Try /CP-reset and then reposition
Cache cleared
FiveM's NUI storage may have been cleared
