Code B1463 Description
The B1463 diagnostic trouble code (DTC) indicates that there is an open circuit in the seat belt switch. This switch is responsible for detecting whether the seat belt is buckled or unbuckled. When the circuit is open, it means that there is a break in the electrical connection, preventing the switch from functioning properly. This can lead to the vehicle's system not recognizing when the seat belt is buckled, which can result in warning lights on the dashboard, chimes or alarms sounding, and potentially affecting the operation of other safety systems like airbags.

- Damaged wiring or connectors in the seat belt switch circuit.
- Loose or corroded electrical connections.
- Faulty seat belt switch.
- Impact or damage to the seat belt system.
- Electrical issues within the vehicle's wiring system.

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.
