Toyota RAV4>> Fuel system and system of production of the fulfilled gases>> Electronic system of injection of fuel>> Diagnostics of electronic system of injection of Toyota TCCS fuel with dynamic ignition
Procedures of diagnostics and the tests provided below, belong only to the Toyota RAV4 cars equipped with system of injection of Toyota TCCS with dynamic ignition.
Electric characteristics of elements of this electronic system of injection of fuel and system of ignition were received by means of the universal measuring device to which specific automobile functions, such as the sensor of frequency of rotation, time of injection of fuel, the oxygen sensor etc. were integrated.
Before carrying out diagnostics surely check:
– system of start-up of the engine (storage battery, starter and wires);
– quality and availability of fuel in a fuel tank;
– system of a retsirkulyatsiya of the fulfilled gases;
– a power supply system air (tightness of branch pipes, laying and various connecting details), the air filter and the thermostat in the filter case;
– an accelerator cable on lack of the slowed-down reset and completeness of opening of a butterfly valve;
– system of ventilation of karterny gases;
– tightness of fuel system;
– compression and engine condition;
– spark plugs;
– safety lock of electronic system of injection of fuel and ignition system.
Procedure of diagnostics should begin with the analysis of malfunctions (symptoms).

Fig. 5.23. Arrangement and numbering of contacts of sockets of the control unit: And — with a mechanical transmission; In — with an automatic transmission


Contacts of electric sockets are designated by figure with a letter, for example, contact 1А — contact of No. of 1 electric socket A (fig. 5.23) .
Check of an electric food of electronic system of injection
All tests of check of an electric food of electronic system of injection of fuel and system of ignition should be carried out at the connected sockets, except for the control unit socket by the engine. Tests of check are provided in tab. 5.2.
Check of electric cопротивления of sensors
All tests of check of electric resistance of sensors should be carried out on control unit sockets by the engine. Tests are provided in tab. 5.3.
Check of an electric food of sensors
All tests of check of an electric food of sensors should be carried out on the control unit socket by the engine. Tests are provided in tab. 5.4.
Check of elements of system of supply of fuel
Check of elements of system of supply of fuel is given in tab. 5.5
Check of the general electric food of electronic system of injection of fuel
All tests of check of the general electric food of electronic system of injection of fuel should be carried out at the connected sockets, except for the control unit socket by the engine. Tests are provided in tab. 5.6.
