A B1944 code means that the vehicle’s onboard diagnostic system has detected a discrepancy in the airbag circuit that is consistent with a poor ground on the #1 sensor, and has registered a trouble code.
Airbag systems are designed to perform self-diagnostics. In the event of a B1944 code, voltages are off spec and indicate a poor ground in the system, registering a trouble code as part of the self-diagnostic process.
As with many codes, technicians often jump ahead on a B1944 code without doing a proper process of elimination and end up replacing parts unnecessarily. A poor reference ground can lead to a false B1944 reading, prompting unnecessary repairs.
A B1944 code can result in the airbag not deploying in the event of a collision.
On many Ford vehicles, the air bag warning light will flash to alert the driver to a problem. The light will flash an indication of the code itself. In this case, it would flash four times, followed by a pause, followed by four flashes to denote 44.
Any airbag-related work is complex and might be best left up to a professional. Accidental deployment of the airbag can result in serious injury.
