Safety & Legal Information
⚠️ IMPORTANT DISCLAIMER
This project modifies safety-critical vehicle systems. Use entirely at your own risk.
- Modifying CAN bus messages can affect vehicle safety systems
- Tesla may remotely detect and disable modified vehicles
- This may void your warranty
- This may be illegal in your jurisdiction
- You are solely responsible for any consequences
Known Risks
Remote Deactivation
As of March 2026, Tesla has begun remotely disabling FSD on vehicles detected using CAN bus mods:
- 2 confirmed cases in China (March 2026)
- Vehicle displays: "Driver assistance service package has been restored to default settings"
- FSD package remains on account but mod no longer functions
- Method appears to be manual (not automated detection)
Community Defense Measures
- Remove SIM card from the vehicle to prevent Tesla from pushing remote changes
- Use airplane mode on the vehicle when possible
- Keep the CAN mod device easily removable for service visits

Legal Considerations
- Right to repair: In many jurisdictions, you have the right to modify your own vehicle
- Type approval: CAN modifications may affect vehicle type approval in EU/regulated markets
- Insurance: Undisclosed modifications may void insurance coverage in case of accidents
- Liability: If an accident occurs while using modified FSD, you bear full responsibility
Safety Best Practices
- Test in a safe environment first — empty parking lot, low speed
- Always be ready to take over — FSD is not fully autonomous
- Keep the mod easily removable — for service visits and emergencies
- Stay updated — follow the community for ban reports and safety issues
- Don't use on public roads until you're confident in the system's behavior
