Procedures of diagnostics and the tests resulted more low, concern only cars Toyota RAV4 equipped with system of injection Toyota TCCS with dynamic ignition.
Electric characteristics of elements of the given electronic system of injection of fuel and ignition system have been received by means of the universal measuring device to which specific automobile functions, such as the gauge of frequency of rotation, time of injection of fuel, the oxygen gauge etc. have been integrated
Before diagnostics carrying out necessarily check up:
– System of start-up of the engine (the storage battery, a starter and wires);
– Quality and fuel presence in a fuel tank;
– System рециркуляции the fulfilled gases;
– The power supply system air (tightness of branch pipes, linings and various connecting details), the air filter and the
thermostat in the filter case;
– An accelerator cable on absence of the slowed down reset and completeness of opening throttle заслонки;
– Ventilation system картерных gases;
– Tightness of fuel system;
– A compression and an engine condition;
– Spark plugs;
– A safety lock of electronic system of injection of fuel and ignition system.
Diagnostics procedure should begin with the analysis of malfunctions (symptoms).
