About B2073

B2073 is a generic (obd-ii standard) body diagnostic trouble code recorded for Ford vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B2073 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 B2073 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 Seat Memory Module monitors its dedicated communication line that links it to seat memory switches and related seat positioning components to confirm correct voltage levels and uninterrupted signal continuity. DTC B2073 is set when the module detects an electrical fault on this line, specifically an open circuit, a short to ground, or a short to battery voltage, preventing reliable transmission of commands and feedback between the seat memory module and the associated seat adjustment components. The communication line is typically a LIN bus or dedicated bidirectional control wire used to c...
