8.3.3. Electric system

The system of passive safety has difficult electric and electronic devices. Handle with system components with care.

Electronic control unit system of passive safety
The control unit gives a signal on blasting safety cushions at frontal collision on an acceleration sensor signal.

Converter of a direct current
The converter of food has blocks of increase and undervoltage which provide the required food of chains of blasting and internal working tension. When falling working tension below a certain size there is its restoration.

Executive sensor / safety sensor
The sensor is built in a chain of blasting a pillow and intended for introduction of system to the working condition at emergence of conditions of blasting. At a normal situation the system is supported in a non-working state. The safety sensor two-contact, electromechanical works at a certain level of acceleration (delay) of the car.

Residual food
The electronic control unit of SRS accumulates the electric power quantity sufficient for carrying out blasting a pillow after shutdown of the main food as a result of collision for some time.

Electronic block of diagnostics of SRS
The block constantly traces the status of SRS at the included ignition and defines emergence of malfunctions of system. Codes of malfunction can be schitana a tester of HI-SCAN (Pro).

Control lamp of malfunction
At malfunction emergence the control unit lights a control lamp for informing the driver on malfunctions in system. After inclusion of ignition six blinkings of a lamp speak about the normal state of system.

Record of codes
At malfunction emergence the control unit writes down the corresponding code in memory. The code is read out and removed a tester of HI-SCAN (Pro).

Data read-out socket (diagnostic socket)
The socket is installed under the forward panel from the driver and intended for connection of external devices, for example a tester of HI-SCAN (Pro).

After operation of a safety cushion the electronic control unit of SRS cannot be reused. Install the new block.
