Code B1999 Description
The B1999 diagnostic trouble code (DTC) refers to a low resistance on the passenger side side-mount airbag squib. In simpler terms, this means that there is an issue with the electrical circuitry in the passenger side airbag system. The squib is a component that initiates the deployment of the airbag in the event of a crash. Low resistance indicates that there is a problem with the electrical connection, which can prevent the airbag from deploying properly or at all.
Common Causes of B1999
- Damaged wiring or connectors in the airbag system
- Faulty passenger side airbag squib
- Corrosion or poor connections in the electrical circuit
- Impact or collision that damaged the airbag system components
Symptoms of B1999
- Airbag warning light illuminated on the dashboard
- Passenger side airbag may not deploy in a crash
- Inconsistent or intermittent airbag system operation
- Diagnostic trouble code B1999 stored in the vehicle's computer system
How to Fix B1999
- Begin by conducting a thorough visual inspection of the airbag system wiring and connectors to check for any visible damage or corrosion.
- Use a multimeter to test the resistance on the passenger side side-mount airbag squib to determine if it falls within the acceptable range.
- If the resistance is outside the specified range, replace the faulty squib with a new one, ensuring proper installation and connection.
- Clear the DTC from the vehicle's computer system using a diagnostic scan tool.
- Perform a test to ensure that the airbag system is functioning correctly and that the warning light is no longer illuminated.
Cost to Fix B1999
The cost of repairing a low resistance on the passenger side side-mount airbag squib can vary depending on the specific cause of the issue and the labor rates in your area. Generally, the parts for this repair, such as a new squib, can range from $100 to $300. Additionally, labor costs can add another $100 to $200 to the total repair bill.

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.
