U047E Invalid Data Received From Restraints System Sensor N
Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo
U047E closes the sensor series: restraints sensor N still sends, but its data are rejected; U017D is lost contact, and the following codes U047F and U0480 move on to belt pretensioner modules. Fourteen external sensors is precisely the maximum Bosch states for its airbag control unit for commercial vehicles. Trucks use such satellites too: Freightliner's campaign SF682 for early 2023-2024 eCascadia replaced AB12 modules because the forward crash sensors had been left unengaged. Which sensor any maker calls N is not published. Airbag lamp on, no MIL.
Likely causes
Corroded connector or damaged line to the sensor
Outdated restraints controller software or wrong sensor configuration
Defective satellite sensor
Symptoms
- Airbag warning lamp on
- Code stored in the restraints controller
