About B2344

B2344 is a generic (obd-ii standard) body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

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.

Because B2344 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The B2344 code indicates a general voltage fault on the seat switch reference voltage positive common circuit, meaning the reference rail is outside the expected operating window without the module distinguishing between an open, a short to ground, or a short to voltage. The seat memory module or driver door module supplies a regulated 5V reference shared across all power seat position switches and continuously monitors the rail. When the supply voltage drifts outside the acceptable range, the module sets this fault. The driver typically experiences erratic or non functional seat positioning a...
