The relay - the general information and check of serviceability of functioning General information For giving of power supply or a management signal on some of consumers of the electric power in the car (such as components of system of injection of fuel, a horn, a starter, the fan of system of cooling, fog lights and other) are used by the relay. Actually the relay represents the electric key providing short circuit In/in a contour on a low-voltage signal. In case of a relay exit out of operation there is a refusal of functioning of the corresponding consumer. Relays are established in the assembly block under the dashboard and in the assembly block in an impellent compartment (see an illustration the Block of the relay and safety locks in an impellent compartment). The description of check of serviceability of functioning of the relay is provided below. The failed relays are subject to replacement. The relay block under the dashboard Check If it is not possible to find out a way of turning on of the relay in the corresponding electric contour according to schemes of electric connections (schemes are provided in the end of head), it is necessary to remember that the approach to check of any relay in principle is identical in all cases. In most cases the management contour always is connected to two of contact plugs of the relay. When giving on these plugs of low-voltage tension the current starts to circulate on a winding of management of the relay therefore there is a short circuit of big contacts of a working contour of the consumer of the electric power. Other plugs are plugs of the worker (In/in) a contour. For the purpose of simplification of identification of plugs of the relay explanatory marking is usually put on its case with the image of the scheme of connection of keys.
