Code B104D Mercury Description
The diagnostic trouble code B104D for Mercury vehicles indicates a problem with the crash zone sensor and other sensor circuits shorting to the power supply. The crash zone sensor is a crucial component in the vehicle's safety system, responsible for detecting impacts and deploying airbags to protect occupants in the event of a collision. When this sensor or its related circuits short to the power supply, it can compromise the proper functioning of the airbag system, potentially leading to airbags not deploying when needed or deploying unexpectedly.
Common Causes of B104D Mercury
- Short circuit in the crash zone sensor or related circuits
- Electrical wiring issues or damaged wiring harness
- Faulty sensor components or connectors
- Water or moisture intrusion in sensor circuits
- Impact damage to the sensor or sensor circuits
Symptoms of B104D Mercury
- Airbag warning light illuminated on the dashboard
- Inconsistent or non-deployment of airbags during a crash
- Faulty or erratic readings from other sensors in the vehicle
- Decreased overall safety performance of the vehicle
How to Fix B104D Mercury
- Use a diagnostic scanner to retrieve the trouble code and pinpoint the location of the short circuit.
- Inspect the crash zone sensor and related circuits for any visible damage or signs of a short circuit.
- Repair or replace damaged wiring, connectors, or sensor components as necessary.
- Clear the trouble code from the vehicle's computer system and test the airbag system for proper functionality.
- Conduct a thorough road test to ensure that the issue has been resolved and the airbags deploy correctly in simulated crash scenarios.
Cost to Fix B104D Mercury
The cost of repairing the crash zone sensor and other sensor circuits shorting to the power supply can vary depending on the extent of the damage, the specific components that need to be replaced, and the labor rates at the auto repair shop. On average, the repair costs for this issue can range from $200 to $500, including parts and labor. However, it is advisable to consult with a qualified mechanic or dealership to get an accurate estimate based on the specific make and model of the vehicle. Additionally, diagnostic time and labor rates at auto repair shops can fluctuate, so it is recommended to inquire about these rates before proceeding with the repair.

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.
Frequently Asked Questions about B104D Mercury Code
