Code B2057 Description

The B2057 diagnostic trouble code relates to the yaw rate sensor in a vehicle's electronic stability control system. The yaw rate sensor measures the rate of rotation around the vehicle's vertical axis, providing crucial data to the vehicle's stability control system to help maintain control during sudden maneuvers or slippery road conditions. When this sensor malfunctions or fails, it can lead to issues with the vehicle's stability control system, potentially affecting the vehicle's handling and safety.

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.
