About B2340

B2340 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 B2340 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

DTC B2340 indicates that the column control module has commanded the column reach (telescoping) motor to move but the feedback potentiometer is reporting no change in column position over the expected response time, meaning the motor has stalled. The module compares the commanded direction against the actual change in the reach feedback signal during a move event, and when the position fails to update or updates very slowly while drive voltage is applied, it identifies a stall condition. Causes range from mechanical binding in the telescoping mechanism, to a seized or open motor armature, to a...
