About B1462

B1462 is a manufacturer-specific body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1462 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1462 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

DTC B1462 is set when the BCM detects a fault in this circuit, typically an open circuit, short to ground, or short to battery voltage. The seat belt switch is a simple normally open or normally closed switch in the buckle assembly that changes state when the latch plate is inserted. When this code is set, the seat belt warning lamp may stay illuminated regardless of buckle status, the seat belt chime may operate continuously or not at all, and on some ve...
