Malfunction of elements of a control system of the engine with the distributed injection (sensors, EBU, nozzles, etc.) causes interruption in supply of fuel and its insufficient giving on various power setting. At the same time the following situations are possible:
1. The engine is started hardly or not started.
2. The engine unstably idles.
3. Riding qualities of the car worsen.
In the presence of one of the specified work violations first of all to execute usual diagnostics, including check of the main systems of the engine (malfunction of system of ignition, wrong adjustment of the engine, etc.). After that to check elements of a control system of the engine with the distributed injection by means of the HI-SCAN device.

NOTE
– Before to remove or install any of elements systems, to consider codes of malfunctions, then to disconnect minus a wire "-" the rechargeable battery.
– Before to disconnect minus a wire of the rechargeable battery, to switch off ignition. The detachment or accession of a wire of the battery at the working engine or the included ignition can cause damage of the control unit of the engine.
– The warmed-up oxygen sensor is connected to EBU screened wires which screens are connected to "mass" of a body for protection against hindrances against system of ignition and a radio noise. At damage of screens to replace wires.
– When checking loading of the generator not to disconnect a wire from a plus conclusion "+" the rechargeable battery to prevent damage of EBU by the increased tension.
– At charging of the rechargeable battery from an external source to disconnect from it minus a wire not to damage EBU.
