About B2238

B2238 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 B2238 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 B2238 is set by the Body Control Module or the Sliding Door Module when it detects an open circuit on the power feed cable that supplies the sliding door electrical system. Power sliding doors use a flexible harness routed through the door hinge or a sliding contact assembly in the door jamb that is subjected to repeated flexing every time the door opens and closes. Over time, and especially in cold climates where insulation becomes brittle, the conductors inside this harness can fatigue and break, leaving the sliding door without power for its motor, latch actuator, switches, courtesy lig...
