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

About B1916

B1916 is a manufacturer-specific body diagnostic trouble code recorded for Ford vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1916 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) 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.

B1916 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

DTC B1916 indicates that the Restraint Control Module (RCM) has detected battery voltage present on the driver airbag squib (deployment loop) circuit when only a controlled low level diagnostic current should be present. The driver squib loop runs from the RCM through the column harness, through the clockspring rotary coupler, and out to the inflator initiator inside the driver airbag module, and is designed to carry only the precise current needed to verify continuity, never a full 12V supply. The RCM monitors the voltage across the loop on every ignition cycle and sets this code when a posit...
