About B2482

B2482 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 B2482 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 B2482 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 Body Control Module (BCM) controls the right front corner lamp (park/marker lamp) by switching the bulb circuit through an internal driver. DTC B2482 is set when the BCM detects battery voltage on the output circuit to the right front corner lamp at a time when it should not be present, indicating a short to battery somewhere in the harness or lamp assembly. The BCM monitors the actual voltage on its lamp output line and compares it against the commanded state to detect this fault, and protects its internal driver from damage when an unexpected source of voltage is detected.
