About B2480

B2480 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 B2480 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 B2480 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 left front corner lamp via a low side driver that switches the lamp ground circuit to turn the lamp on. The corner lamp typically functions as part of the parking lamp or front marker lamp circuit on the left front corner of the vehicle. DTC B2480 sets when the BCM detects voltage on the left front corner lamp output circuit when it should not be present, meaning the wire is shorted to battery positive somewhere between the driver and the lamp socket. When this code is active the corner lamp may remain illuminated continuously regardless of switch pos...
