Code B252A Dodge Description

The B252A diagnostic trouble code (DTC) is specific to Dodge vehicles and indicates a problem with the decklid (trunk lid) release control circuit. This code is triggered when the powertrain control module (PCM) detects a low voltage condition in the circuit responsible for controlling the decklid release mechanism. The decklid release system is typically activated by a switch located on the key fob, inside the vehicle, or on the trunk itself. When the circuit is functioning correctly, it allows for the trunk to be opened remotely or manually with ease.
