Safety locks, the relay and breakers - the general informationSafety locks
The majority of safety locks is placed together with the relay in the special assembly block established under the panel of devices a passenger foot well. Safety locks of some of additional systems (ABS, К/В) can be established in the separate holders fixed in the left part of an impellent compartment. On diesel models safety locks of system of preheat and the fan of system of cooling can settle down also in an impellent compartment of the car.
For the purpose of providing of access to safety locks turn out a fixing clamp and, having developed the book, liberate the assembly block from the panel of devices. The list of safety locks is resulted in last Section of the present Chapter. For access of the safety locks located in an impellent compartment open a cowl cover, release clamps and a cover from the corresponding holder.
At all do not replace the beaten out safety lock calculated on higher nominal (on a current strength) loading. The extremely vicious practice is restoration of the failed safety lock by перемыкания its contacts by means of a metal foil.
If the replaceable safety lock fails right after food givings in a contour, hence in a chain the short circuit which reason should be revealed and eliminated takes place. If the checked safety lock is used for protection simultaneously several electric contours, try to reveal a faulty chain by serial inclusion of each of under control contours, excluding thereby obviously serviceable.
The electric scheme of the relay
The relay represents the electromechanical switch used mainly in power chains. The electric scheme of the relay of a typical design is presented on an illustration.
The majority of relays used on the car are placed in the general with safety locks the assembly block. Additional relays (type of the relay of system of preheat of the diesel engine) are located in an impellent compartment.
For the purpose of providing of access to the relay turn out a fixing clamp and, having developed the book, liberate the assembly block from the panel of devices.
If there are suspicions that refusal any of electric contours is connected with failure of the relay of its management, include corresponding system - the serviceable relay at giving on it of a food should publish distinctly heard click. If click is distributed, means, a cause of a failure is malfunction of actually working component, or electroconducting failure. Otherwise, takes place or infringement of giving of a food, or the relay is faulty actually. Check of a condition of the relay is made by substitution on its place obviously serviceable. Thus it is not necessary to forget that external similarity of two relays not so necessarily is a guarantee of identity of a principle of their functioning.
For relay replacement, first of all, switch off a corresponding electric contour. Then the relay can be easily removed a way вытягивания it from a reception nest. Establish to the place of the removed relay new, with corresponding working parametres.
