Code B1B19 Description
The B1B19 diagnostic trouble code (DTC) indicates that there is a high voltage condition in the circuit for the left side curtain squib 1 in the vehicle's supplemental restraint system (SRS), also known as the airbag system. The curtain squib is a component responsible for deploying the side curtain airbag in the event of a side impact collision to provide additional protection for occupants.
Common Causes of B1B19
- Faulty left side curtain squib 1
- Wiring or connection issues in the circuit
- Corrosion or damage to the connectors
- Faulty SRS module
- Electrical issues such as short circuits or high resistance in the circuit
Symptoms of B1B19
- Illumination of the airbag warning light on the dashboard
- Inability to deploy the left side curtain airbag in a crash
- Diagnostic trouble code B1B19 stored in the vehicle's computer system
- Loss of communication with the SRS module
How to Fix B1B19
- Begin by diagnosing the specific cause of the high voltage condition in the left side curtain squib 1 circuit using a scan tool to retrieve the DTC and perform electrical testing.
- Inspect the wiring harness and connectors for any signs of damage, corrosion, or loose connections. Repair or replace any damaged components as necessary.
- Test the left side curtain squib 1 for proper functionality and resistance. Replace the squib if it is found to be faulty.
- Clear the DTC from the vehicle's computer system using the scan tool and perform a test drive to ensure that the airbag system is functioning correctly.
- If the issue persists, further diagnostic testing may be required to pinpoint the exact cause of the high voltage condition in the circuit.

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.
