TRUNK RELEASE CONTROL MODULE. The trunk release control module is an electronic component of the vehicle comfort system responsible for controlling the trunk lock actuator and enabling remote or automatic opening of the luggage compartment. The module receives signals from the key fob, interior release button, central locking system or keyless entry system and sends a control signal to the electric latch actuator. The unit typically includes a control circuit board, switching relays or transistors, microcontroller and electrical connectors integrated into the vehicle electrical network. Depending on vehicle design the module may operate as a standalone control unit or as part of the body control module or central locking system. Failure symptoms may include trunk not opening from the key or interior switch, delayed actuator response, unintended trunk opening or system fault codes. Causes may include electronic component failure, connector corrosion, wiring faults or software malfunction. Our catalog includes genuine OEM trunk release modules, quality aftermarket replacements and inspected used electronic units without housing damage or overheating marks. Used modules are tested for connector integrity and electronic functionality. Selection is based on VIN number, vehicle configuration and part number. Proper replacement restores reliable trunk opening function and integration with the vehicle central locking system.
