CHECK

1. If in system of injection of fuel there is a damage, at first be convinced that all sockets of electroconducting of system are reliably connected and not oxidised. Be convinced that the filtering element of the air filter is pure, spark plugs - in a good condition, backlashes of spark plugs are correctly adjusted, a compression in engine cylinders in norm, the corner of an advancing of ignition is exposed correctly, hoses сапуна the engine are not littered and not damaged. 2. If as a result of these checks the problem reason it was not possible to reveal, for test it is necessary to address in accordingly equipped centre Renault. The socket of electroconducting of the block is included in a chain of a control system by the engine to which it is possible to connect a special electronic diagnostic tester; the socket is attached скобами to a partition in impellent branch. The tester will define damage quickly and simply, needlessly to check all components of system separately that takes away a lot of time and can lead to damage ECU. 3. If during movement on the instrument panel the control lamp “malfunction of electronics” lights up, or it burns more than 3 seconds after ignition inclusion, malfunction can be in one or several following components: a) the pressure Gauge in the pipeline. b) the Potentiometer throttle заслонки. Injectors. d) the Step-by-step motor of adjustment of idling (not on all engines). e) the Gauge of speed of the car (during movement). f) the Electromagnetic valve recycling the fulfilled gases (only engines K7M and F3R). g) the Computer of automatic transmission. 4. It is possible to check up resistance of some separate components, using the information in Specifications, however other knots (idling) cannot be checked up and adjusted the step-by-step motor of management (address to illustrations).

ADJUSTMENT

1. Skilled motorists with considerable experience and in the presence of the equipment (including a tachometre and precisely calibrated analyzer of the fulfilled gases) can check up level WITH and idling turns. However if adjustment is required, it is necessary to address on HUNDRED Renault. A mix (level WITH) and idling turns are not regulated, and if any of these sizes is wrong, in system of injection of fuel there is a damage.
