A combined ignition switch (lock) is used to switch the main circuits of the vehicle, consisting of a contact part and a mechanical anti-theft device with a lock.
A special feature of the car's electrical system is the connection of a number of elements (windshield washers, interior lights, door locks, electric windows, mirror and rear window heaters, rear fog light, side lights, etc.) via the electronic control unit for the interior electrical equipment and anti-theft alarm.
The diagrams of the main electrical systems of the car are given at the end of the book.
WARNINGS: Carry out any work on the vehicle's electrical equipment only with the battery disconnected.
The battery can only be disconnected or connected when the ignition is off.
When checking the circuits of electrical equipment, it is prohibited to short-circuit the wires to ground (check the circuits for serviceability "for a spark"), as this may lead to failure of the electrical equipment elements. It is prohibited to use fuses that are not provided for by the design of the car or designed for a higher current, as well as to use wire instead of fuses.
It is prohibited to disconnect the battery while the engine is running to avoid damage to the voltage regulator and electronic components of the vehicle.
When carrying out electric welding work on a vehicle, it is necessary to disconnect the wires from the terminals of the battery, generator and electronic engine control unit.
When recharging the battery using a charger, disconnect the vehicle's electrical wiring from the battery terminals.
