About B2329

B2329 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 B2329 is stored, the module has detected an open (broken or disconnected) electrical path 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 B2329 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 B2329 indicates that the column control module has detected an open circuit in the column reach feedback potentiometer signal path, meaning the module cannot read any voltage from the position sensor that monitors the telescopic travel of the power adjustable steering column. The reach potentiometer normally returns a smoothly varying voltage between approximately 0.5V and 4.5V as the column moves through its range. An open in the signal wire, the 5V reference, the sensor ground, or inside the potentiometer itself will cause the signal to sit at full reference voltage or fall to zero, whic...
