B16F7 (15) — Driver Active Headrest Control Circuit

System: Body  |  Type: Manufacturer-Specific  |  Make: Ram

About B16F7

B16F7 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 B16F7 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.

B16F7 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 Active Head Restraint (AHR) system on Ram trucks deploys the driver headrest forward during certain rear impact events to help reduce whiplash injury to the occupant. The Occupant Restraint Controller (ORC), or in some architectures the Body Control Module, continuously monitors the integrity of the driver headrest deploy circuit by checking the actuator solenoid or pyrotechnic release mechanism for correct circuit resistance. DTC B16F7:15 is logged when the controller detects an open circuit condition on the driver active headrest control wires, meaning the expected actuator load was not ...
