About B2897

B2897 is a generic (obd-ii standard) body diagnostic trouble code recorded for Holden vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B2897 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit; and 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 B2897 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 Body Control Module (BCM) or steering column lock control module monitors the steering column lock motor control circuit for correct voltage and current flow during lock and unlock commands. DTC B2897 is set when the module detects either battery voltage present on the motor control circuit when it is not commanded, or no electrical continuity in the circuit when operation is requested. The steering column lock motor is an electrically driven actuator that engages or releases a locking pin in the steering column as part of the passive theft deterrent and electronic ignition system.
