About B16FB

B16FB is a manufacturer-specific body diagnostic trouble code recorded for Ram vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B16FB is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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.

B16FB 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) monitors the passenger active headrest actuator circuit, which deploys during certain rear impact events to help reduce whiplash injuries. DTC B16FB:15 is stored when the ORC detects an open circuit condition in the passenger active headrest control circuit. The fault is set if the module commands the actuator but no expected current flow or feedback is measured, indicating a break in continuity. When this code is active the airbag warning lamp is illuminated and the active headrest function is disabled, meaning the passenger restraint system will not de...
