9.7. System of electronic injection of fuel self-diagnostics mode
|
Attention!
On cars after 1996 problem diagnostics in fuel and auxiliary systems is carried out only in car-care center. Light-emitting diode indicators on these cars are absent.
|
It is possible to define failure of sensors and actuation mechanisms by diagnostic codes of processor system ECCS of the car. 5 working hours 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, pointing to a poor mix, or dies away pointing to a rich mix. On the cold engine regulation is carried out on the opened cycle, the indicator or constantly burns or dies away.

5.5 Scheme of check of a tank. At a purge in the union A air should not pass, through both unions In air passes freely
|
Mode 2 feedback tracking at stabilization of a stekhiometriya of a mix. When the structure of a mix is stabilized in certain limits the red indicator at the same time with the green blinks. During the opened cycle of regulation the red indicator constantly burns (or 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 a food of the processor block.
Mode 4 diagnostics of a condition of switches of a butterfly valve, starter, sensor of speed of the car, etc.
Mode 5 diagnostics in real time for check in road conditions.
Mode choice (the engine with system of direct injection of fuel, 19901995)
Include ignition and turn the switch of modes clockwise (photo) to the full, wait the beginnings 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 modes counter-clockwise. Ignition not to switch off, the mode 1 otherwise will automatically be established.

|
6.2 For installation of a mode translate the switch to the left 1. Side view 2. An observation port for alarm lamps 3. Mode 4 switch. Processor block 5. Top view
|
For check of codes warm up the engine and establish a mode 3. For definition of a code count 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 established a mode 4), and then counter-clockwise.

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