About B2593

B2593 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 B2593 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 B2593 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 B2593 fault code is set when the Power Sliding Door (PSD) control module detects unexpected door movement in the opening direction while it was actively commanding a close operation. The module tracks door position via hall effect or encoder feedback from the drive motor, and compares actual position change against the commanded direction. If the door reverses or opens during a close command without the obstacle detection logic triggering it, this code logs the conflict. The driver may notice that the PSD refuses to close on the affected side, repeatedly stalls partway through closure, or ...
