U047BInvalid Data Received From Restraints System Sensor K
- Generic OBD-II code · Network
- How the car detects it
- U047B: restraints sensor K is heard but its values are rejected; U017A covers lost contact. No manufacturer documents the letter K publicly, so its position stays open. Eleven satellites point to a large system, yet not every function needs one of its own: Bosch's AB premium controller can house rollover and inertial sensing internally and accepts as many as 18 PSI5 sensors. Where curtains also deploy in a rollover, FMVSS 226 requires a readiness indicator and lets NHTSA ask the carmaker to describe the deploying sensor system. Airbag lamp on, no MIL.
