U017ALost Communication With Restraints System Sensor K
- Generic OBD-II code · Network
- How the car detects it
- U017A is logged when restraint sensor K, the eleventh remote crash sensor, has stopped sending data to the restraints module. No manufacturer documents U017A publicly; the Chrysler Jeep lists in NHTSA file PE11-019 end at the sixth satellite. Why J2012 reserves so many slots becomes clear from supplier data: a current Bosch airbag control unit serves 12 PSI5 sensor interfaces, a premium version up to 18. Higher letters therefore belong to well-equipped vehicles, for example with rear-impact sensors, which Bosch also lists as a mounting option. After rear-end repairs or work in the boot floor, check first whether such a sensor was reconnected. Deployment that depends on sensor K may be switched off; the airbag lamp lights, the MIL stays off.
