About B2357

B2357 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 B2357 is stored, the module has detected a signal or supply voltage lower than the expected operating range.

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 B2357 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 driver door module controls the driver window motor and monitors motor current draw during operation to detect obstructions and to manage the anti pinch and one touch down functions. DTC B2357 sets when the module detects that the current sense signal on the window down operation reads lower than the expected threshold for normal motor loading, indicating a failure in the current sensing circuit or an abnormally low motor load. The current sense path typically uses a low value shunt resistor in series with the motor return path, with the voltage across the shunt fed to an internal module a...
