9.7. System of electronic injection of fuel self-diagnostics mode


Attention!
On cars after 1996 failure diagnostics in fuel and auxiliary systems is carried out only in car service. LED indicators on these cars are absent.

The failure of sensors and actuation mechanisms can be defined by diagnostic codes of the processor ECCS system of the car. 5 operating modes of system of self-diagnostics are provided.
Mode 1 signals from the oxygen sensor. The mode of the closed cycle of automatic control works at the heated-up engine. In this case the green indicator burns, indicating poor mix, or dies away indicating rich mix. On the cold engine regulation is carried out on the opened cycle, the indicator or constantly burns or dies away.

6.1 Installation of the mode


5.5 Схема проверки бачка. При продувке в штуцер А воздух проходить не должен, через оба штуцера В воздух проходит свободно
5.5 Scheme of check of a tank. At a purge in the union A air should not pass, In air passes through both unions freely


The mode 2 tracking of feedback at stabilization of a stekhiometriya of mix. When the composition of mix is stabilized in certain limits the red indicator along with green blinks. During the opened regulation cycle the red indicator constantly burns (or it is switched off).
Mode 3 self-diagnostics mode. All refusals are brought in memory. Contents of memory are erased after 50 inclusions of a starter or at interruption of power supply of the processor block.
Mode 4 diagnostics of a condition of switches of a butterfly valve, starter, car speed sensor, etc.
The mode 5 diagnostics in real time for check in road conditions.
The choice of the mode (the engine with system of direct injection of fuel, 19901995)
Include ignition and turn the switch of the modes clockwise (photo) to the full, wait for the beginning of a blinking of a lamp. After the number of flashes of a lamp becomes equal to number of the chosen mode immediately turn the switch of the modes counterclockwise. Not to switch off ignition, otherwise the mode 1 will automatically be set.

For check of codes warm up the engine and set the mode 3. For definition of a code count the number of flashes of green and red lamps (number of units and tens, respectively). Upon termination of remove memory contents, having turned the switch clockwise (having set the mode 4), and then counterclockwise.

The choice of the mode on the engine with system of preliminary injection (with Tbisistemoy)
If necessary to define a mode code (for example in case of sharp deterioration in operation of the engine) get the processor block from under a passenger seat. Not to disconnect sockets as the kept codes will be destroyed. Include ignition and transfer the switch of the choice of the mode to the included state (photo) red and green indicators will begin to blink. After 3 blinkings of indicators (the mode 3 is set), transfer the switch to the switched-off state. For definition of a code count the number of flashes of green and red lamps (number of units and tens, respectively).
Upon termination of remove memory contents, having set the mode 4, or having disconnected the battery from weight. At installation of the mode 4 indicators have to blink 4 times.
