About B2331

B2331 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 B2331 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

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 B2331 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 B2331 indicates that the column control module has detected the column reach feedback potentiometer signal pulled down to or near chassis ground, well below the normal 0.5V to 4.5V operating range of the sensor. The reach potentiometer feeds a smoothly varying position signal back to the module so it can track and limit the telescoping travel of the power adjustable steering column. When the module reads zero or a value at the bottom of the sensor scale, it identifies a short to ground in the signal path. With this code active the power column reach function is typically disabled, memory r...
