About B2141

B2141 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 B2141 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 B2141 is set when a control module (most commonly the Body Control Module or PCM) detects that the configuration data stored in its Non Volatile Memory (NVM) is missing, corrupted, or does not match what is expected for the vehicle. The NVM holds vehicle specific options such as VIN, model variant, security identifiers, and feature configuration that the module uses to operate correctly. The code typically appears after a module has been replaced and not yet configured, after a failed software flash, or when the internal memory has been corrupted by low voltage during programming.
