5.8.2. Check of a control system of the engine

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