Code B1B19 Chrysler Description
The B1B19 code is a diagnostic trouble code (DTC) specific to Chrysler vehicles, indicating a malfunction in the left side curtain airbag squib circuit. The term "squib" refers to the small explosive device that ignites the airbag deployment mechanism. When the code is triggered, it signifies that the airbag control module has detected an open circuit or a high resistance in the left side curtain squib circuit. This could prevent the airbag from deploying in the event of a collision, compromising passenger safety.
Common Causes of B1B19 Chrysler
- Damaged Wiring: Frayed or broken wires in the left side curtain squib circuit can lead to high resistance or an open circuit.
- Corroded Connectors: Moisture or dirt can cause corrosion at the connectors, affecting the electrical connection.
- Faulty Airbag Module: A malfunctioning airbag control module may incorrectly interpret the circuit status and trigger the code.
- Deployment History: Previous airbag deployments may have damaged the squib or associated wiring.
- Improper Repairs: Previous repairs or modifications to the airbag system may have introduced faults or poor connections.
Symptoms of B1B19 Chrysler
- Airbag Warning Light: The airbag warning light on the dashboard may illuminate, indicating a fault in the airbag system.
- Inoperative Airbags: The left side curtain airbags may not deploy during a collision, posing a significant safety risk.
- Diagnostic Trouble Code (DTC) Presence: The B1B19 code will be stored in the vehicle's onboard diagnostic system.
- Inconsistent Airbag Performance: There may be intermittent issues with the airbag system, such as delayed deployment or failure to deploy under certain conditions.
- Potential Error Messages: The vehicle's onboard computer may display error messages related to the airbag system, prompting further investigation.
How to Fix B1B19 Chrysler
- Diagnostic Scan: Begin with a thorough diagnostic scan to confirm the presence of the B1B19 code and check for any additional codes that may provide more context.
- Visual Inspection: Inspect the wiring and connectors associated with the left side curtain airbag squib circuit for any signs of damage, corrosion, or loose connections.
- Repair or Replace Wiring/Connectors: If damaged wiring or corroded connectors are found, repair or replace them as necessary to restore proper electrical flow.
- Test Airbag Module: If the wiring and connectors are intact, test the airbag control module for faults. Replace it if it is determined to be faulty.
- Clear Codes and Test: After repairs, clear the diagnostic trouble codes and conduct a test drive to ensure the airbag system is functioning correctly and the warning light does not reappear.
Cost to Fix B1B19 Chrysler
The cost to repair the B1B19 code can vary widely based on the specific issue and the labor rates in your area. On average, repair costs can range from $150 to $600.

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.
