Central Locking Relay

The central locking relay is actually a control module consisting of a microprocessor, two relay coils for voltage supply to the central locking motors and a transistor for ground signal to the interior lighting.

The central locking relay receives control signals from the central locking modules and activates the car's central locking system, interior lighting and alarm relay.

The central locking relay is located in the central relay module in the car.

Connections for the central locking relay on position D/G:

Positions D and G are the same as B and A in the wiring diagram.
