Code B1912 Description
The B1912 diagnostic trouble code indicates an issue with the airbag diagnostic monitor ground circuit short to ground. This means that there is a problem with the electrical connection between the airbag diagnostic monitor and the ground, which could potentially impact the proper functioning of the airbag system in the vehicle. The airbag diagnostic monitor is responsible for monitoring the airbag system and ensuring that it is functioning correctly. A short to ground in this circuit can prevent the monitor from receiving the necessary signals and data to effectively monitor the airbag system, potentially leading to a malfunction or failure in the event of a collision.
Common Causes of B1912
- Corroded or damaged wiring in the airbag diagnostic monitor ground circuit.
- Poor electrical connections between the airbag diagnostic monitor and the ground.
- Faulty airbag diagnostic monitor.
- Issues with the airbag control module.
- Previous accident or collision causing damage to the airbag system components.
Symptoms of B1912
- Airbag warning light illuminated on the dashboard.
- Inability to turn off the airbag warning light even after resetting.
- Airbag system failure message displayed on the instrument cluster.
- Airbags may fail to deploy in the event of an accident.
- Diagnostic trouble code B1912 stored in the vehicle's computer system.
How to Fix B1912
- Begin by conducting a thorough visual inspection of the airbag diagnostic monitor ground circuit, checking for any visible signs of damage, corrosion, or loose connections.
- Use a multimeter to test the continuity and resistance of the wiring in the ground circuit to identify any potential short to ground issues.
- If necessary, repair or replace any damaged wiring or connectors in the airbag diagnostic monitor ground circuit.
- Test the airbag diagnostic monitor and the airbag control module to ensure they are functioning correctly. Replace any faulty components as needed.
- Clear the diagnostic trouble code from the vehicle's computer system and perform a test drive to confirm that the issue has been resolved.
Cost to Fix B1912
The cost of repairing a B1912 code can vary depending on the extent of the damage and the specific components that need to be replaced. In general, the repair costs for this issue can range from $200 to $500, including parts and labor. However, it is important to note that the actual cost may be higher or lower based on factors such as the make and model of the vehicle, the location of the repair shop, and the hourly labor rates.

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.
