Code B0057 GMC Description
The B0057 GMC code indicates that there is a problem with the right front/passenger pretensioner deployment loop resistance being too low. The pretensioner is a safety feature in the vehicle's seatbelt system that activates in the event of a collision to tighten the seatbelt and reduce the forward movement of the occupant. The deployment loop resistance being low means that there is an issue with the electrical circuit that controls the pretensioner, potentially preventing it from functioning properly in a crash.
Common Causes of B0057 GMC
- Faulty pretensioner deployment loop.
- Wiring issues or short circuits in the pretensioner circuit.

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.
