Code B1C48 Chrysler Description
The B1C48 Chrysler code indicates a problem with the 1st row passenger retractor tensioner circuit being too high. In simpler terms, this means that there is an issue with the seatbelt system in the front passenger seat of the vehicle. The retractor tensioner is responsible for tightening the seatbelt in the event of a collision or sudden stop, ensuring the passenger is securely held in place to prevent injury. A high circuit reading suggests that there is excessive resistance in the circuit, which can prevent the tensioner from functioning properly.
Common Causes of B1C48 Chrysler
- Damaged wiring in the retractor tensioner circuit.
- Faulty retractor tensioner mechanism.
- Corrosion or debris in the seatbelt mechanism.
- Issues with the airbag control module.
- Impact or collision that damaged the seatbelt system.
Symptoms of B1C48 Chrysler
- Airbag warning light illuminated on the dashboard.
- Seatbelt warning light flashing or staying on.
- Seatbelt not retracting properly.
- Audible warning chime when seatbelt is not buckled.
- Inability to properly secure the seatbelt.
How to Fix B1C48 Chrysler
- Begin by diagnosing the specific cause of the high circuit reading using a diagnostic scanner to pinpoint the exact issue.
- Inspect the wiring in the retractor tensioner circuit for any damage or corrosion, repairing or replacing as necessary.
- Test the retractor tensioner mechanism to ensure it is functioning properly, replacing it if found to be faulty.
- Check the seatbelt mechanism for any obstructions or damage, cleaning or replacing components as needed.
- Reset the airbag control module and clear the diagnostic trouble codes to ensure the issue is resolved.

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.
