Code B1941 Lincoln Description
The B1941 diagnostic trouble code for Lincoln vehicles indicates a problem with the right front airbag crash sensor feed/return circuit being open. This means that there is an issue with the electrical circuit that connects the right front airbag crash sensor to the vehicle's airbag control module. The crash sensor is a crucial component of the vehicle's safety system, as it is responsible for detecting impacts and triggering the deployment of the airbags in the event of a collision. When this circuit is open, it means that the sensor is not able to communicate with the airbag control module, potentially compromising the effectiveness of the airbag system in the event of an accident.

- Damaged wiring or connectors in the right front airbag crash sensor circuit
- Faulty right front airbag crash sensor
- Issues with the airbag control module
- Corrosion or moisture in the sensor circuit
- Impact or collision that damaged the sensor or wiring

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
