B2493 is a body diagnostic trouble code. It identifies a fault related to LF PARK LAMP OUTPUT CIRCUIT Short to Battery. The body control / restraints module monitors this circuit or component continuously and sets B2493 when the signal or value is outside the expected range, implausible or missing.

The base function may still work, but performance can be affected, so the fault should be diagnosed. Diagnosis generally means inspecting the related wiring, connectors and power/ground references, then verifying the component against specification with a scan tool.
