B1922 — Airbag Safing Sensor Output Circuit Short To Battery

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

About B1922

B1922 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 B1922 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.

B1922 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 Restraints Control Module (RCM) monitors the dedicated output circuit from the safing sensor, which is an independent acceleration sensor used to confirm a genuine crash event before allowing airbag deployment. DTC B1922 is set when the RCM detects that this output line is being held at battery voltage instead of the expected low signal voltage range (typically anything above 5V indicates a short to battery condition). The safing sensor provides a redundant deployment authorisation signal in parallel with the main crash sensors, so a short to battery makes the RCM unable to validate crash ...
