Code B0064 Description
The B0064 diagnostic trouble code (DTC) indicates that there is a low resistance in the deployment loop of the left front/driver pretensioner in the vehicle's safety system. The pretensioner is a crucial component of the vehicle's safety restraint system, specifically the seatbelt system. When a collision is detected, the pretensioner tightens the seatbelt to minimize the movement of the occupant and reduce the risk of injury.
Common Causes of B0064
- Damaged wiring or connectors in the deployment loop.
- Faulty pretensioner mechanism.
- Corrosion or moisture damage in the wiring.
- Impact damage to the pretensioner system.
- Malfunctioning airbag control module.
Symptoms of B0064
- Airbag warning light on the dashboard.
- Seatbelt warning light may be illuminated.
- Inability to properly secure the seatbelt.
- Faulty deployment of the seatbelt in a collision.
- Increased risk of injury to the driver in the event of a collision.
How to Fix B0064
- Diagnose the issue by using a scan tool to read the DTC and identify the specific problem area.
- Inspect the wiring and connectors in the deployment loop for any damage or corrosion, and repair or replace as necessary.
- Test the resistance in the pretensioner deployment loop to ensure it is within the manufacturer's specifications.
- If the pretensioner mechanism is faulty, replace it with a new unit.
- Clear the DTC from the vehicle's memory and test the system to ensure proper function.
Cost to Fix B0064
The cost of repairing a B0064 DTC can vary depending on the specific cause of the issue and the labor rates in your area.

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.
