 The models of cars considered in the present manual are equipped with system of additional safety (SRS). Before starting performance of any works near the block of a safety cushion, a steering column or the dashboard, disconnect SRS in order to avoid receiving injuries at its casual operation (see the Section System of Additional Safety (SRS) - the device and the principle of functioning)! It is easy to distinguish an electrical wiring of a chain of SRS on yellow color of isolation.


General information

The module of management, assembly of the switch/activator of a driver's door, and also activators of locks of passenger doors and door of a back (Legacy Station wagon/Outback model) are among components of the uniform lock.

Blocking/unlocking of a driver's door by means of the internal switch of the lock leads to blocking/unlocking of all other doors of the car. The schematic diagram of the uniform lock is submitted on an illustration.

As a subsystem the system of remote control which main components are the module of management of the uniform lock which is built in a key head a remote control (transmitter), door switches, and also lamps of the alarm system and saloon lamps is a part of the uniform lock.

The DU panel functions on a radio frequency that allows to use the transmitter from any directions.
