What are the VAZ 2110 fuse box relays responsible for?
K1 – relay for monitoring the health of light bulbs; K2 – front wiper relay; K3 – repeater and alarm relay; K4 – low beam relay; K5 – high beam relay; K6 – additional relay; K7 – relay for turning on the heated rear window; K8 – backup relay (not installed on 110 series vehicles);
F1-F20 in the diagram are fuses. The circuits in the car are protected by fuses based on a certain rated current (in A). The battery charging circuit, generator circuit, ignition and engine starting are exceptions.
To replace a faulty fuse, first find the one that has blown, then eliminate the reason why it was damaged and then install a new one. Below is a list of fuses and information on each one.
* Never replace fuses with jumpers, this can lead to failure of various components and elements, including failure of the wiring tracks in the fuse box and even a car fire.
Mounting block of fuses and relays VAZ 2109
| This page presents two types of fuse and relay blocks: with finger fuses (old mounting block), with blade fuses (new type mounting block). The location of the fuse box is shown. A table has been posted with a breakdown of each fuse and relay indicating the electrical circuits they protect. There are two electrical diagrams of the internal connections of the fuse mounting blocks. Two diagrams of pinout of connecting sockets of electrical wire blocks are presented. The sequence of dismantling the fuse mounting block of a VAZ 2109 passenger car is described. |
