5.8.2. Check of a control system by the engine

EBU constantly receives a food from the storage battery through a conclusion «70» protected by the fuse No. 41
(7,5 And), being in the assembly block of a motor compartment. At turning on of the switch of devices and a starter tension of the storage battery moves on a conclusion «38» EBU sockets and on the electromagnetic valve of regulation of a corner of an advancing of injection of fuel on a chain protected by the fuse No. 25 (10 And), being in the assembly block of salon of the car. Thus the conclusion «4» EBU sockets is connected on "weight". The double power chain of the main relay of a food of system joins. Tension moves on conclusions «56», «61», «116» and «117» EBU sockets, and also on a conclusion «2» switches of provision of a pedal of management of supply of fuel. At this time a food arrives on two HORNS electromagnetic valves and the electromagnetic valve of an air zaslonka on a chain protected by the fuse No. 16 (10 And), being in the assembly block of safety locks of salon of the car. At connection on "mass" of a conclusion «111» EBU sockets work the relay of prestarting heating. Glow plugs receive a food during time depending on temperature of cooling liquid. Permission to start-up of the engine arrives on a conclusion «20» EBU sockets on a chain protected by the fuse No. 26 (7,5 And), being in the assembly block of salon of the car. On cars with the EBU conditioner turns on through a conclusion of "15" blocks of the socket the compressor by means of the relay of turning on of the conditioner and the relay of pressure of a coolant depending on power setting.
Checks carry out according to indications of tab. 3.19 — 3.21. Precautionary measures and preliminary checks are given above in подразд. «Check of a control system by the CD20 engine».
If as a result of checks malfunctions whereas signs of malfunctions are present are not revealed, replace EBU (in the last turn).
