Code B13B3 Description
The B13B3 diagnostic trouble code refers to an issue with the Second Row Left Inflatable Seatbelt Deployment Control Circuit. In modern vehicles, inflatable seatbelts are a safety feature that combines the traditional seatbelt with an airbag-like component. This system is designed to provide additional protection in the event of a collision by distributing the force of impact over a larger area of the body.
Common Causes of B13B3
- Faulty sensor in the inflatable seatbelt deployment control circuit.
- Damaged wiring or connectors in the system.
- Malfunctioning control module responsible for deploying the seatbelt.
- Corrosion or water damage affecting the circuit components.
- Impact or collision that damaged the inflatable seatbelt system.
Symptoms of B13B3
- Airbag warning light illuminated on the dashboard.
- Inflatable seatbelt system not deploying properly during a crash test.
- Audible warning chime indicating a fault with the seatbelt system.
- Second-row left seatbelt not tightening properly during sudden braking.
How to Fix B13B3
- Diagnose the issue using a diagnostic scanner to retrieve the specific fault codes.
- Inspect the wiring harness and connectors for any signs of damage or corrosion.
- Test the sensor and control module for proper functionality.
- Replace any faulty components, such as sensors, wiring, or control modules.
- Clear the fault codes and reset the system to ensure proper operation.
Cost to Fix B13B3
The typical repair costs for addressing the B13B3 code can vary depending on the extent of the issue and the specific components that need to be replaced. In general, repairing the Second Row Left Inflatable Seatbelt Deployment Control Circuit can range from $200 to $500, including parts and labor. However, it is important to note that the actual cost may be higher or lower based on the specific diagnosis time and labor rates at auto repair shops, as well as the make and model of the vehicle.

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.
