U0151Lost communication with restraints control module (airbags)
U0151 means “Lost communication with restraints control module (airbags)”. It's a generic network code (lost communication with a module), so it means the same on every make, including VW, Škoda, Audi, SEAT and Cupra.
- Urgent
- SystemNetwork
- TypeGeneric (same on all makes)
- Safetyairbags
How urgent is it?
This code points at a safety system: airbags. Get this inspected by a professional. If the warning light is on, treat the system as not working until it has been checked.
Which system and module
Scanline files it under Network. The first letter, U, means network (communication between modules).
Network codes can be stored by any module on the car's data network; on VW Group cars the Gateway (VCDS address 19) often stores them too.
What usually causes it
- That module's power or ground
- CAN wiring
- low battery voltage
These are the usual suspects for a professional to confirm, not repair steps.
