About B1C2D

B1C2D is a manufacturer-specific body diagnostic trouble code recorded for Jeep vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1C2D is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1C2D is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Occupant Restraint Controller (ORC) continuously monitors the resistance of the right side seat thorax airbag squib circuit through a small low level current to confirm the squib is electrically intact and ready to deploy. The thorax squib is a small initiator located inside the right side seat mounted thorax airbag that, when energised by the ORC during a side impact event, ignites the airbag propellant. DTC B1C2D is set when the ORC measures resistance above the calibrated upper threshold on the right thorax squib 1 circuit, indicating an open or high resistance condition. When the code ...
