Restraints Deployed
The restraint control module reports that one or more airbag or pretensioner stages have been deployed. The engine ECU latches this and runs the crash strategy - fuel cutoff, hazard lights, unlock central locking, disable cruise. The code can only be cleared after the restraint module is reset (typically requires module replacement).
