Code B141C Description
The diagnostic trouble code B141C refers to an issue with the Second Row Passenger Inflatable Seatbelt Deployment Control Circuit. In modern vehicles, inflatable seatbelts are designed to provide additional protection in the event of a collision by distributing the force of impact over a wider area. The control circuit is responsible for managing the deployment of the inflatable seatbelt to ensure it activates when needed.
Common Causes of B141C
- Faulty second-row passenger seatbelt deployment sensor
- Damaged wiring harness connecting the control circuit
- Defective control module responsible for managing the inflatable seatbelt deployment
- Corrosion or poor electrical connection in the circuit
- Impact or physical damage to the inflatable seatbelt system
Symptoms of B141C
- Airbag warning light illuminated on the dashboard
- Second-row passenger seatbelt not deploying during a crash test
- Audible warning chime indicating a fault in the airbag system
- Second-row passenger seatbelt not locking in place during sudden braking
- Vehicle diagnostic scan reveals B141C code stored in the system
How to Fix B141C
- Begin by conducting a comprehensive diagnostic scan to confirm the presence of the B141C code and identify the specific cause of the issue.
- Inspect the second-row passenger seatbelt deployment sensor and wiring harness for any signs of damage or wear. Replace any faulty components as needed.
- Test the control module for proper functionality and replace it if it is determined to be the source of the problem.
- Clear the diagnostic trouble code from the system using a scan tool after completing the repair to ensure the issue is resolved.
- Conduct a thorough test of the inflatable seatbelt system to verify that the control circuit is functioning correctly and the second-row passenger seatbelt deploys as intended.

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.
