Code B1B19 RAM Description
The B1B19 RAM code indicates a problem with the Left Side Curtain Squib 1 Circuit in the vehicle's airbag system. The curtain squib is a component that helps deploy the side curtain airbags in the event of a collision or sudden impact. When this circuit is registering a high voltage, it means that there is an issue with the electrical connection or component itself. This can prevent the airbag from deploying properly in the event of an accident, compromising the safety of the vehicle occupants.
Common Causes of B1B19 RAM
- Faulty Left Side Curtain Squib 1
- Wiring or connector issues in the circuit
- Corrosion or damage to the airbag system components
- Electrical interference or short circuits
- Issues with the airbag control module
Symptoms of B1B19 RAM
- Airbag warning light illuminated on the dashboard
- Side curtain airbags not deploying in a crash
- Diagnostic trouble codes related to the airbag system
- Loss of power to the airbag system
How to Fix B1B19 RAM
- Begin by diagnosing the specific cause of the high circuit voltage, using a scan tool to retrieve the trouble codes and pinpoint the issue.
- Inspect the wiring and connectors in the Left Side Curtain Squib 1 circuit for any damage, corrosion, or loose connections. Repair or replace as necessary.
- Test the Left Side Curtain Squib 1 component itself to ensure it is functioning correctly. Replace if faulty.
- Clear the trouble codes from the airbag system and reset the system to ensure proper operation.
- Perform a thorough test drive to confirm that the issue has been resolved and the airbag system is functioning as intended.
Cost to Fix B1B19 RAM

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.
