THE GENERAL DATA

Moisture hit on any details and sockets of an electric equipment of fuel system is not supposed. Special attention it is necessary to give to such knots as the block of protective relays and a socket of the switch throttle заслонки which is not water-proof and at moisture hit fails.

Before gymnastics the battery should be removed from the car. It is forbidden to disconnect the battery from weight on the working engine as because of sharp jump of pressure can fail the processor block and automatic control devices.

At replacement of details or at system check be convinced that the ignition key is in position OFF. If it is necessary to measure pressure on a socket of a cable of the block of management (or the processor block) that at first disconnect from the block all wires then translate the ignition key in position ON.

At check of details of an electric equipment by a tester it is forbidden to rest a tester probe against a socket conclusion, otherwise a conclusion it is possible сдеформировать and contact will be broken. A probe to a socket to attach only from outside wires.

Conclusions of sockets of atomizers, the switch throttle заслонки, an air regulator of idling and the temperature gauge self-blocked. For рассоединения such sockets it is necessary to pull a reciprocal part of a socket, simultaneously slightly shaking in the parties.

Low-voltage cables it is necessary to have not less than in 100 mm from the wires which are under a high voltage. It is not supposed to check постукиванием such details as the gauge of measurement of a stream of air, the gauge of an angle of rotation cranked a shaft, a socket of the block of management. Details of system of injection of fuel are established with a split-hair accuracy. The slightest infringement of their installation will cause considerable deterioration of characteristics of the engine.

It is forbidden to include the fuel pump empty, otherwise pump details quickly wear out (fuel provides greasing of rubbing details of the pump). It is forbidden to use other fuel, than gasoline.
