B1468 — Chime Input Request Circuit Failure

System: Body  |  Type: Manufacturer-Specific  |  Make: Generic

About B1468

B1468 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 B1468 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.

B1468 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.

Code Information

The Body Control Module (BCM), or in some vehicles the Instrument Cluster, manages audible chime alerts by monitoring chime input request lines from various switches and modules such as the seat belt buckle switch, door ajar switches, key in ignition switch, and headlamp switch. DTC B1468 sets when the BCM detects an electrical fault on a chime input request circuit, typically an open, a short to ground, or a short to battery on the input wire that prevents the BCM from reading a valid request state. The chime output may be provided by an integrated driver in the BCM or instrument cluster, or ...
