Diagnostics of systems of electronic control


The scheme of connection of the button and, if necessary, a light-emitting diode to the 2-contact or 30-contact diagnostic socket

 

 

At emergence of malfunctions in system of ignition and supply of fuel on the dashboard the control lamp zagoatsya. At the same time the monitor switches to emergency operation and writes down malfunction. After an engine stop record of malfunction can be a schitana from memory of the device.

It is possible to carry out a survey of memory of malfunction of the monitor by means of the OUT 304 097 T device or by means of the diagnostic station Citroyon 26A.

The device is connected to the diagnostic socket.

At each interruption in supply of food on the monitor data from memory are erased!

The electronic anti-theft device becomes more active again.

Indication of a code of malfunction means that this malfunction was shown after the last cleaning of memory.

For elimination of malfunction check all constructive group.

When checking the fuel pump and operating idling valve indication of malfunction (codes 15 or 22) does not mean that all constructive group is faulty. In case of malfunction also connections and conducting have to be checked.

Poll of memory of malfunctions by means of an auxiliary light-emitting diode

Reading of codes can be made both with use of the special scanner, and on a lamp of refusals on the dashboard or by means of a light-emitting diode.

 PERFORMANCE ORDER

1. Make connection of the button according to the scheme (see the illustration Scheme of Connection of the Button and, if necessary, a light-emitting diode to the 2-contact or 30-contact diagnostic socket) to contact 2 two-contact or C2 of the 30-contact socket (depending on model) and to the case. If on your model there is no control lamp of refusals, connect the light-emitting diode cathode to the diagnostic plug of the socket or the control unit according to the scheme (depending on model), and the light-emitting diode anode — to "+" - the battery plug.
2. Include ignition and leave included.
3. Press the button on 5 sec. and release. The light-emitting diode or a lamp of refusals will give a code 12 — the beginning of delivery of codes. Value of each category of a code corresponds to the number of flashes lasting 1 sec. At first tens of a code are transferred, then — units. Between categories — a pause in 1,5 sec. After a pause 2,5 sec. delivery of a code repeats.
For extraction of the following code press the button again, and so before emergence of a code 11, обозначающегот the termination of a conclusion or lack of codes of malfunctions — if it appeared right after a code 12.
4. Disconnect wires and switch off ignition.
For removal of codes from memory of the block it is enough to press after delivery of a code 11 the button and to hold it during not less than 15 sec., or just to disconnect a negative cable from the rechargeable battery not less than on 10 sec.
