Since 1993 of release

Repair and car operation

Diagnostics of systems of electronic control

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

At occurrence of malfunctions in system of ignition and fuel giving on the instrument panel загоается a control lamp. Simultaneously the monitor is switched to emergency operation and writes down malfunction. After a stop of the engine malfunction record can be считана from memory of the device.

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

The device is connected to a diagnostic socket.

At each stopping delivery of a food on a monitor the data from memory is erased!

The electronic antijoy ride device again becomes more active.

Indication of a code of malfunction means that the given malfunction was shown after last clearing of memory.

For malfunction elimination check up all constructive group.

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

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

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

PERFORMANCE ORDER

1. Make button connection according to the scheme (the Scheme of connection of the button and see an illustration, at necessity, a light-emitting diode to a 2-contact or 30-contact diagnostic socket) to contact 2 two-contact or С2 a 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 a socket or the management block 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 сек and release. The light-emitting diode or a lamp of refusals will give out a code 12 — the beginning of delivery of codes. Value of each category of a code corresponds to quantity of flashes by duration 1 seconds At first tens code, then — units are transferred. Between categories — a pause in 1,5 seconds After a pause 2,5 сек code delivery repeats.
For extraction of a following code again press the button and so before occurrence of a code 11, обозначающегот the termination of a conclusion or absence of codes of malfunctions — if it has 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 11 to press ambassador of delivery of a code the button and to keep it during not less 15 сек, or simply to disconnect a negative cable from the storage battery not less than on 10 seconds
