U0479Invalid Data Received From Restraints System Sensor I
- Generic OBD-II code · Network
- How the car detects it
- U0479 records that restraints sensor I sends data the airbag controller refuses; U0178 would be silence. No public source assigns the letter I to a mounting point, and a ninth peripheral sensor is rarely documented. Rear impact sensors are one way to reach such counts: Bosch offers its peripheral acceleration sensor for installation at the back of the vehicle, and on MCI coaches service instruction ITS-60877 had a rear impact accelerometer in baggage bay three moved because luggage could trigger it. Airbag lamp on, no MIL.
