Daihatsu PG21MS 12281DR Lock Control Unit

Daihatsu Lock Control Unit PG21MS 12281DR is the electronic module that oversees a vehicle’s central locking system. This Daihatsu component processes inputs from lock and unlock commands—such as door switches and remote entry—and sends the appropriate drive signals to the door lock actuators to secure or release the vehicle’s doors. Identified by part number 12281DR and associated with the PG21MS designation, this unit serves as the central controller for a Daihatsu locking setup. As a dedicated Daihatsu part, it functions as the control hub that coordinates locking and unlocking across the system, enabling synchronized operation of multiple doors when commands are received and helping ensure consistent response to user input. The controller typically interacts with the vehicle’s electrical system to manage timing and sequence of actuator activity, and is intended for use within Daihatsu central locking configurations that rely on the PG21MS/12281DR module. For accuracy in replacement or repair, the exact part number and designation must match the vehicle’s locking circuitry to ensure proper communication within the vehicle’s electrical system.
