Code B1B54 Description
The B1B54 code indicates a problem with the 1st row passenger seat belt sensor circuit being too low. This sensor is responsible for detecting whether the passenger seat belt is buckled or unbuckled. When the sensor circuit is reading a low signal, it means that the system is not detecting the seat belt being properly secured, which can pose a safety risk in the event of a collision. This code is typically triggered by a fault in the sensor circuit, wiring, or connections related to the passenger seat belt system.
Common Causes of B1B54
- Faulty seat belt sensor.
- Damaged wiring or connectors in the seat belt circuit.
- Corrosion or debris affecting sensor functionality.
- Loose or disconnected connections in the seat belt system.
- Impact or damage to the passenger seat affecting sensor readings.
Symptoms of B1B54
- Airbag warning light illuminated on the dashboard.
- Audible warning chime indicating a seat belt issue.
- Passenger airbag light indicating that it is disabled.
- Inability to engage the passenger airbag when the seat belt is buckled.

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.
