Code B1941 Scion Description
The B1941 Scion code indicates an open circuit in the selectable force limiter squib right circuit. In simpler terms, this code points to a problem with the right side airbag system in the vehicle. The selectable force limiter squib is a component within the airbag system that helps regulate the force with which the airbag deploys in the event of a crash. An open circuit in this component means that there is a break or disconnect in the electrical pathway, preventing the airbag from functioning properly.
Common Causes of B1941 Scion
- Wiring issues: Damage or corrosion in the wiring harness connecting the squib to the airbag control module can cause an open circuit.
- Faulty squib: The selectable force limiter squib itself may be defective or damaged, leading to an open circuit.
- Blown fuse: A blown fuse in the airbag system can disrupt the electrical connection to the squib.
- Airbag control module fault: Problems with the airbag control module, such as a malfunction or software issue, can trigger this code.
Symptoms of B1941 Scion
- Airbag warning light: The most common symptom associated with this code is the illumination of the airbag warning light on the vehicle's dashboard.
- Non-deployment of airbag: In the event of a collision, the right side airbag may fail to deploy or deploy incorrectly.
- Diagnostic trouble codes: The vehicle's onboard diagnostic system may store additional trouble codes related to the airbag system.
- Intermittent airbag operation: The airbag may work intermittently, leading to inconsistent protection for passengers.
How to Fix B1941 Scion
- Diagnose the issue: Use a diagnostic scanner to retrieve the specific trouble code and perform a thorough inspection of the airbag system to identify the cause of the open circuit.
- Check wiring and connections: Inspect the wiring harness for damage, corrosion, or loose connections. Repair or replace any faulty wiring as needed.
- Test the squib: Test the selectable force limiter squib for continuity and proper operation. Replace the squib if it fails the test.
- Check fuses: Inspect the fuses related to the airbag system and replace any blown fuses.
- Clear codes and test: Once the repair is complete, clear the trouble codes from the vehicle's memory and test the airbag system to ensure proper functionality.

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.
