About B2241

B2241 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 B2241 is stored, the module has detected 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 B2241 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 B2241 is set by the Body Control Module when it detects a short to ground condition on the rear cargo door lock actuator output circuit. The BCM drives the cargo door lock actuator with a switched output, and it monitors load current and voltage on this output to confirm correct operation. When the output is commanded high but the voltage stays pulled to ground, or when excessive current is drawn indicating a low resistance fault path, the BCM sets this code and disables the output to protect itself from damage. With this code set, the rear cargo door lock will not respond to lock or unloc...
