Code B0133 Description
The B0133 diagnostic trouble code (DTC) indicates a short to battery in the right seat belt pretensioner squib circuit. The seat belt pretensioner is a safety feature that tightens the seat belt in the event of a collision to reduce the risk of injury to the occupant. The squib is an electrical component that initiates the pretensioner's activation. A short to battery in this circuit means that there is an unintended connection to the vehicle's battery power, which can lead to the pretensioner deploying unexpectedly or not deploying at all in the event of a crash.

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.
