When the right front impact sensor is not mounted correctly or if the ground circuit is open, it can lead to a malfunction in the airbag system, potentially compromising the vehicle's safety in the event of an accident.
Common Causes of B1944 Mercury
- Impact sensor not properly mounted to the vehicle.
- Loose or damaged wiring connections to the impact sensor.
- Corrosion or damage to the impact sensor itself.
- Faulty ground circuit connection.
- Previous collision or impact causing damage to the sensor or wiring.
Symptoms of B1944 Mercury
- Airbag warning light illuminated on the dashboard.
- Right front airbag may not deploy in a collision.
- Diagnostic trouble code B1944 stored in the vehicle's computer system.
- Loss of confidence in the vehicle's safety systems.
How to Fix B1944 Mercury
- Begin by visually inspecting the right front impact sensor and its mounting location for any signs of damage or improper installation.
- Check the wiring connections to the impact sensor for looseness, corrosion, or damage. Repair or replace any faulty wiring as needed.
- Test the ground circuit for continuity and repair any open circuits if necessary.
- Clear the diagnostic trouble code from the vehicle's computer system using a scan tool.
- Test the airbag system to ensure proper functioning of the right front impact sensor and airbag deployment.

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.
