System of additional safety (SRS) - the device and a functioning principleThe general information
Some of models considered in the present Management are equipped by system of additional safety (SRS), more known under the name of pillows of safety. The system provides additional protection of the driver and the forward passenger of the car at strong front and (at a corresponding complete set) lateral blows. The module of a driver's face-to-face pillow of safety is placed inside ступичной parts of assemblage of a steering wheel (the Suspension bracket and a steering see the Head).
The module of a passenger pillow of safety is located on the right under the panel of devices of the car on which surface the warning inscription in the form of abbreviation SRS or AIR BAG is thus put. Lateral pillows of safety (at a corresponding complete set of the car) are built in in external lateral walls of backs of forward seats.
Control lamp SRS/AIR BAG, spring contact drum of assemblage concern number of other components SRS подрулевых switches, the management module (ECU) SRS with built in in it the gauge of the directed overloads (G-gauge) and the control gauge, individual gauges of the directed overloads of pillows of safety and connecting electroconducting.
The scheme an arrangement of components SRS
Principle of functioning SRS
At strong front blow of the car gauges of forward pillows of safety, and also built in in ECU SRS the G-gauge and the control gauge provide short circuit of a chain of activation of pillows.
Modules of pillows of safety
Pillow activation (ек) safety occurs under condition of operation of gauges of directed overloads SRS. Short circuit of a chain of the module of a pillow of safety leads to almost instant filling with last with the nitrogen allocated as a result of combustion порошкообразной of a mix азида of sodium with оксидом of copper.
In case of failure of the onboard storage battery the system is switched to a food from the reserve source built in in module SRS and providing independent development of the electric power within even 20 seconds. It is necessary to notice that the passenger pillow of safety usually is more on volume, than driver's, and is equipped by the metal bearing case, at module operation divided into two half, and a finishing cover.
Spring contact drum
The drum is established on steering columns and represents contact in the form of a spiral spring. By means of a contact drum giving a food from a plait of electroconducting of a steering column to placed in a steering wheel nave (and consequently mobile) to the module of a driver's pillow of safety is provided.
The management module
ECU SRS provides power supplies giving to modules of pillows of safety at the moment of the collision causing strong enough directed overloads. System operation occurs even in case of emergency refusal of the onboard storage battery. Interrogation of a condition of components SRS is made by the module at each start of the engine and accompanied by short-term operation built in in the panel of devices of the car of a control lamp “AIR BAG/SRS”. In case of an exit any of knots out of operation switching-off of a control lamp do not occur. Operation of a control lamp testifies to malfunction in system also during movement, - in a similar situation the car should be driven away as soon as possible on a car repair shop.
Check of condition SRS should be made time in 10 years.
Dismantle and service of components of a steering column, radio receiver and the other components located near to the panel of devices demands observance of special safety measures as casual damage of electroconducting SRS can lead to unapproved operation of pillows of the safety, fraught with reception of serious traumas. Electroconducting SRS is easy for identifying on bright yellow colouring of isolation, - at all do not disunite its contact sockets and do not connect to them any electric diagnostic devices.
Do not try to make at all measurement of resistance of components SRS, - developed by the internal power supply of an ohmmeter of energy can quite enough for operation газогенераторов!
Before to use on the car any electronic equipment it is necessary to make necessarily switching-off SRS (see more low).
At all do not throw out never worked modules of pillows of safety in мусороприемники, - consultations on recycling of components SRS always can be received on car repair shops.
System SRS switching-off
For switching-off of pillows of safety make following manipulations:
For system activation connect to the battery at first a positive wire, then - negative, turn the ignition key in position and make sure of serviceability of operation of control lamp SRS.
