On a Ram, B274D-11 reports the passenger side seat thorax squib 1 control shorted to ground. The seat mounted side airbag on the passenger side has a firing wire touching ground somewhere, and the module will not arm the system while that reading stands.
Squib 1 is the firing element in the passenger seat side airbag, and the ORC keeps its two control wires at a controlled voltage while the truck runs. A short to ground drags one of those wires down to chassis potential. The module sees the voltage where it should not be, stores B274D-11, and disables deployment for that position.
Short to ground is a physical problem in almost every case. Something has worn through insulation, crushed a wire, or bridged a pin to metal. That is why the repair is usually found by hand and by eye under the passenger seat rather than by swapping parts, and why a new airbag installed before the wiring is checked tends to leave the light on.
Nothing here is stored crash information. The module is watching that circuit in real time, so the code reflects present conditions and drops out once the short is repaired and the system passes its startup check. Crash records live in a different part of the module memory, get written only when airbags deploy, and stay there until a reset removes them.
Do not expect a reset to solve this. The ORC checks the passenger thorax circuit on every key cycle, and a wire still touching ground puts B274D-11 back immediately. The wiring repair comes first. If the passenger seat airbag has already deployed and the module is also holding a crash record, mail the module to us once the truck side repairs are finished and we clear that record.
Our lookup files B274D-11 under Ram. It sits alongside B274C on the driver side, and the -11 suffix identifies the failure as a short to ground, which is how Chrysler built systems separate one wiring complaint from another.
Get under the passenger seat and trace the SRS harness with your hands from the floor connector to the seat back before you order parts. Look for flattened insulation, a wire trapped under a seat bolt, and any sign of water. Unplug the airbag next and see whether the short follows the harness or stays with the seat. If the inflator is shorted internally, we sell genuine OEM seat side airbags and can confirm the correct part by VIN at 501-988-0611. Related codes: B274C-13, B2761-49, B1B00.
Trace the wiring and connectors first. If the module still holds the fault after the repair, mail it to us and we will clear it.
