Code B1996 Mercury Description
The B1996 diagnostic trouble code for Mercury vehicles indicates a problem with the passenger side side mount airbag circuit, specifically a short to battery voltage. This means that there is an abnormal electrical connection that is causing the airbag system to receive a higher voltage than it should, potentially leading to a malfunction or deployment issue. The side mount airbag is an important safety feature in modern vehicles, designed to provide protection in the event of a side impact collision. Therefore, any issues with the airbag system should be addressed promptly to ensure the safety of the vehicle occupants.
Common Causes of B1996 Mercury
- Short circuit in the wiring harness leading to the passenger side side mount airbag.
- Faulty airbag module or sensor.
- Corrosion or damage to electrical connectors in the airbag system.
- Issues with the vehicle's battery or charging system.
- Impact damage to the vehicle that may have affected the airbag system.
Symptoms of B1996 Mercury
- Airbag warning light illuminated on the dashboard.
- Inability to deploy the passenger side side mount airbag in a collision.
- Intermittent or erratic airbag system behavior.
- Loss of communication with the airbag module.
- Stored trouble codes related to the airbag system.
How to Fix B1996 Mercury
- Begin by diagnosing the specific cause of the short to battery voltage in the passenger side side mount airbag circuit using a diagnostic scanner.
- Inspect the wiring harness for any signs of damage, corrosion, or short circuits. Repair or replace any damaged wiring as needed.
- Check the airbag module and sensor for proper operation. Replace any faulty components.
- Test the airbag system after repairs are completed to ensure that the code is no longer present and that the system functions correctly.
- Clear the trouble codes from the vehicle's onboard computer to reset the airbag system and turn off the warning light.
Cost to Fix B1996 Mercury

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 B1996 Mercury Code
1. What does the OBDII code B1996 mean on a Mercury?
B1996 indicates a short to battery voltage in the passenger side side-mount airbag circuit, which can prevent proper airbag deployment in an accident.
2. What are the common symptoms of code B1996?
Symptoms may include the airbag warning light illuminated on the dashboard and potentially a non-functioning passenger side side-mount airbag.
3. What causes the B1996 code on a Mercury?
Common causes include damaged wiring, a shorted airbag module, corroded connectors, or an internal fault in the airbag control module.
4. Is it safe to drive with the B1996 code active?
It is not recommended to drive with this code active, as it may indicate that the passenger side airbag will not deploy properly in a collision.
5. How can I diagnose the B1996 code on my Mercury?
Diagnosis involves inspecting the wiring and connectors for damage or corrosion, testing the airbag circuit for proper voltage, and using a scan tool to confirm the issue.
6. Can I fix the B1996 code myself?
If you're experienced with automotive electronics, you can attempt to repair damaged wiring or connectors, but replacing airbag components should be handled by a professional due to safety concerns.
7. How much does it cost to fix the B1996 code on a Mercury?
The repair cost can range from $100 to $1,000, depending on whether the issue is a simple wiring repair or if airbag module replacement is required.
8. Will clearing the B1996 code with a scan tool fix the problem?
Clearing the code will not fix the underlying issue. The root cause, such as a short circuit or component failure, must be repaired first.
9. Can a faulty airbag control module cause the B1996 code?
Yes, a malfunctioning airbag control module can cause this code if it is unable to properly regulate the airbag circuit voltage.
10. How do I prevent the B1996 code from occurring again?
Regularly inspect the airbag system wiring for damage, avoid tampering with airbag components, and address any electrical issues promptly.
