Code B104D Lincoln Description
The B104D diagnostic trouble code for Lincoln vehicles indicates that there is a short to power supply in the crash zone sensor and other sensor circuits. The crash zone sensors are a crucial part of the vehicle's safety system, as they are responsible for detecting impacts and deploying airbags when necessary. When there is a short to power supply in these circuits, it can lead to malfunctions in the sensors, potentially causing the airbags not to deploy in the event of a crash. This issue poses a significant safety risk to the vehicle occupants, as airbags are a critical component in reducing the severity of injuries during collisions.
Common Causes of B104D Lincoln
- Damaged wiring in the crash zone sensor circuits.
- Faulty crash zone sensor.
- Short circuit in the electrical system.
- Issues with the vehicle's main power supply.
- Corrosion or loose connections in the sensor circuits.
Symptoms of B104D Lincoln
- Airbag warning light illuminated on the dashboard.
- Airbags not deploying during a collision.
- Erratic behavior of other safety systems such as seat belt pretensioners.
- Intermittent electrical issues throughout the vehicle.
How to Fix B104D Lincoln
- Begin by conducting a thorough inspection of the crash zone sensor circuits to identify the location of the short to power supply.
- Repair or replace any damaged wiring or faulty sensors in the affected circuits.
- Check for and address any short circuits in the electrical system that may be causing the issue.
- Test the repaired circuits to ensure that the short to power supply has been resolved.
- Clear the diagnostic trouble code from the vehicle's computer system and perform a final test to confirm that the airbag system is functioning correctly.

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.
