Airbag Driver/Passenger Circuit Short To Ground
B1913 — Airbag Driver/Passenger Circuit Short To Ground
System: Body | Type: Manufacturer-Specific | Make: Ford
B1913 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 B1913 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.
B1913 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.
DTC B1913 indicates that the Restraint Control Module (RCM) has detected a short to chassis ground on the driver or front passenger airbag squib (deployment loop) circuit. The RCM continuously monitors the resistance of each airbag loop by sending a small diagnostic current through the squib and measuring the voltage drop, and it sets this code when the measured resistance falls below the manufacturer specified threshold, indicating that the high side or low side conductor is touching chassis metal. The driver airbag circuit passes through the clockspring (rotary coupler) in the steering colum...
