 Models of cars considered in the present Management are equipped by system of additional safety (SRS). Before to start performance of any works near to the block of a pillow of safety, a steering column or the instrument panel, disconnect SRS in order to avoid reception of traumas at its casual operation (the Section System of additional safety (SRS) - the device and a functioning principle see)! Electroconducting of chain SRS is easy for distinguishing on yellow colour of isolation.


The general information

The number of components of the uniform lock includes the management module, assemblage of the switch/activator of a driver's door, and also activators of locks of passenger doors and a back door (model Legacy of Universal/Outback).

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 basic scheme of the uniform lock is presented on an illustration.

As a subsystem the structure of the uniform lock includes the remote control system which basic components are the module of management of the uniform lock, built in a head of a key a remote control (transmitter), door switches, and also lamps of the alarm system and салонных fixtures.

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