Code B13B7 Description
The B13B7 diagnostic trouble code (DTC) refers to a fault in the Second Row Right Inflatable Seatbelt Deployment Control Circuit. In modern vehicles, inflatable seatbelts are designed to provide enhanced safety and protection for passengers in the event of a collision. The control circuit is responsible for managing the deployment of the seatbelt in response to crash sensor data, ensuring that it inflates at the right time and with the correct force.
Common Causes of B13B7
- Damaged wiring or connectors in the inflatable seatbelt deployment circuit
- Faulty seatbelt inflator module on the second row right side
- Malfunctioning crash sensor sending incorrect data to the control module
- Defective control module responsible for managing the seatbelt deployment system
Symptoms of B13B7
- Airbag warning light illuminated on the dashboard
- Second row right seatbelt not deploying properly during a crash simulation
- Audible warning chime indicating a fault with the inflatable seatbelt system
- Diagnostic trouble code (DTC) stored in the vehicle's computer system
How to Fix B13B7
- Begin by conducting a thorough visual inspection of the wiring and connectors in the Second Row Right Inflatable Seatbelt Deployment Control Circuit. Look for any signs of damage, corrosion, or loose connections that may be causing the issue.
- Use a multimeter to test the continuity of the wiring and connectors to identify any open circuits or short circuits that need to be repaired.
- Check the seatbelt inflator module on the second row right side for any signs of damage or malfunction. Replace the module if necessary.
- Inspect the crash sensor for proper operation and replace it if it is sending incorrect data to the control module.
- Test the control module responsible for managing the seatbelt deployment system and replace it if it is found to be faulty.
Cost to Fix B13B7
The cost of repairing a Second Row Right Inflatable Seatbelt Deployment Control Circuit issue can vary depending on the extent of the damage and the specific components that need to be replaced. On average, the parts for this repair can range from $200 to $500, while the labor costs can range from $150 to $300. Keep in mind that these are rough estimates, and actual costs may vary based on the vehicle make and model, as well as the labor rates in your area. It is recommended to consult with a professional mechanic to get a more accurate cost estimate for this repair.

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.
Frequently Asked Questions about B13B7 Code
1. What does the OBDII code B13B7 mean?
B13B7 indicates an issue with the second-row right inflatable seatbelt deployment control circuit, which is part of the vehicle's supplemental restraint system (SRS).
2. What are the symptoms of code B13B7?
Common symptoms include the airbag warning light illuminated on the dashboard and possible inoperability of the second-row right inflatable seatbelt system.
3. What causes the B13B7 code to appear?
Possible causes include damaged wiring or connectors in the seatbelt circuit, a faulty inflatable seatbelt module, or a malfunctioning SRS control unit.
4. Is it safe to drive with the B13B7 code active?
Driving with the B13B7 code active is not recommended, as it may compromise the proper functioning of your vehicle's airbag and seatbelt systems in the event of a collision.
5. How is the B13B7 code diagnosed?
A technician will use a scan tool to confirm the code, inspect the wiring and connectors for damage, and test the inflatable seatbelt module and SRS control unit for faults.
6. Can I fix the B13B7 code myself?
