B1914 — Airbag Crash Sensors #1 / #2 Circuit Short To Ground

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

About B1914

B1914 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 B1914 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit; and a sensor-related fault — the reported value from the named sensor is out of spec.

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.

B1914 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 B1914 indicates that the Restraint Control Module (RCM) has detected a short to chassis ground on the wiring between the RCM and the front impact (crash) sensors mounted at the front of the vehicle. These remote front crash sensors provide an early deceleration signal to the RCM during a collision, allowing the module to confirm a frontal impact and deploy the appropriate airbags and pretensioners within the very short available time window. The RCM continuously monitors the impact sensor circuit during each ignition cycle and sets this code when the measured circuit voltage or resistance ...
