Work must be carried out in a well-ventilated area, preferably with open windows and doors to create a draft.
Do not use open flames, electric welding or tools that may generate sparks. Make sure that a charged fire extinguisher is in the immediate vicinity of the work area.
Use goggles to protect your eyes from fuel getting into them. If fuel gets on your skin, rinse the area with plenty of water.
The container containing the fuel contains its vapors and is potentially explosive.
When working with the fuel system, keep it clean, as dirt that gets into the system channels can block them, which will disrupt the normal operation of the engine.
The use of an electronic engine management system provides the following advantages:
- thanks to the optimal supply of fuel to the engine in all operating modes, fuel consumption is reduced while maintaining the dynamic characteristics of the vehicle;
- more complete combustion of fuel and the use of a catalytic converter reduce the emission of harmful substances with exhaust gases;
- since the electronic engine management system detects and records faults in its memory, their search and detection is significantly accelerated;
- the engine management system sets the optimal ignition timing, moment and amount of fuel supplied to the engine in all operating modes. The engine management system interacts with other vehicle systems, in particular with the automatic transmission control system or the anti-theft system.
The engine management system components are very reliable and require virtually no maintenance. Maintenance only requires replacing the air filter and spark plugs. Inspection, adjustment and repair of the engine management system require the use of sophisticated, expensive equipment, so these jobs must be performed at a specialized service station.
During vehicle operation, there is no need to adjust the idle speed or CO content in the exhaust gases.
When servicing or repairing the vehicle's ignition system with the ignition on, care must be taken to avoid electric shock from the high-voltage part of the ignition system. People with pacemakers are not recommended to have the engine management system checked or repaired. Turn off the ignition before disconnecting or connecting any ignition system component or meter leads.
The fuel system is constantly under pressure even after the engine is turned off, so before carrying out any work on the fuel system, it is necessary to relieve the pressure.
To prevent the possibility of an accidental short circuit in the electrical circuit and damage to the electronic components of the engine management system, always remove the ground cable from the battery.
Before performing any work on the engine management system, recall the faults stored in it from memory. Also check the tightness of the fuel and air supply systems to the engine.
Normal engine management system operation this is only possible if the voltage in the vehicle's electrical system is not lower than 11.5 V.
If after work on the control system the engine starts and stops after a short time, it may be switched off by the anti-theft system. In this case, recall the faults stored in the memory and, if necessary, adjust the engine control system.
