8.3.3. Electric system

The system of passive safety has difficult electric and electronic devices. Address with system components carefully.

Electronic control unit system of passive safety
The control unit gives out a signal on blasting safety cushions at face-to-face collision on a signal of the sensor of acceleration.

Converter of a direct current
The converter of a food has blocks of increase and fall of tension which provide a demanded 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 system introduction in a working condition at emergence of conditions of blasting. At a normal situation the system is supported in a non-working condition. The safety sensor two-contact, electromechanical works at a certain level of acceleration (delay) of the car.

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

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

Control lamp of malfunction
At malfunction emergence the control unit lights a control lamp for informing of the driver on malfunctions in system. After ignition inclusion six blinkings of a lamp speak about a 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 HI-SCAN (Pro) tester.

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

After safety cushion operation the electronic SRS control unit cannot be used repeatedly. Establish the new block.
