About B2374

B2374 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.

When B2374 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.

Because B2374 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

On vehicles with power sliding doors, the door latch assembly includes position switches that report secondary (detent) and primary latch positions to the sliding door control module. The detent or latch switch tells the module the door has reached the secondary position so the cinch motor can pull it fully closed. DTC B2374 sets when the sliding door control module detects a general failure on the power sliding detent or latch position switch circuit, meaning the input is not changing state correctly through a door cycle or is reading invalid values. When this code is set, the power sliding d...
