Diagnostics of defects

The description of diagnostics of electronic tax systems and diagnostic Kodes are provided in the head the electric equipment of the motor.

In this office the simplest scheme of an explanation of the reasons of defects and refusals which happen in knot and systems of transport is offered. Refusals and its possible reasons on groups after a sign of the relation with certain components or systems of the car, such as the motor was tired, the cooling system, etc., besides, in the text of the instruction on chapters and offices are given concerning with these problems.

They remember that the successful end of search of the reasons of defect is a black magic which is not available at the disposal of only the skilled professional mechanic at all, and clears up from a combination of a certain knowledge and patient, systematic approach to a problem research. To move always it simple needs too difficult from to be taken away each check till the logical end and, to worry, the obvious facts - not to pass everyone can forget to correct fuel in the tank or to give Leuchtgeräte for the night it is made.

And, at last, it is always necessary to try it is necessary to form a distinct picture of development of defect and to take the corresponding steps after prevention of return. If the failure of the electric equipment owing to violation of quality of contact happened, check by the way a condition of all other contacts and electric plugs of system. If the same protection device continues to burn through repeatedly in turn, the sense in its following compensation is not made - it is necessary to try to find out a cause of failure. They remember that accident of a minor component can be a sign of violation of functioning of more important knot or all system.

The motor not proworatschiwajetsja in attempts of its start

1. Corrosion of clips of the battery is available or strengthening of tops of lines on them became weak. Check a condition of clips and tops. Tighten klemmnyje clips, remove corrosion traces if it is necessary.
2. The battery is unloaded or wrong. If tops of lines are found pure and of course are strengthened on battery clips, turn the ignition key in position of ON, then header searchlights of und\oder cleaners of a windshield will accept. If this electric equipment does not function, the battery is unloaded.

3. This internal or external vytecheniye of the cooled liquid available.
4. It is a heater cover incorrectly. Check pressure cover.

The address of the cooled liquid is wounded

1. Appropriately water pump does not function. The motor from functioning of the pump pereschaw the top hose of the heater at the worker on not aggravated changes is most of all simpler to be convinced. If at hose otpuskanii the blow of liquid within it is felt, the pump functions regularly (watch chapter of the cooling system, heating).
2. Passability of the cooling system is wounded. Pull together the cooled liquid, erase system and do from its fresh mix (in time watch chapter of the cooling system, heating). If such need arises, take the heater (expect the head of the cooling system, heating) and you carry out this obratnopototschnuju linen.
3. priwodnoj of belts of the water pump is worn-out or it is damaged or regulation of its tension (it is wounded watch chapters Routine maintenance and the motor).
4. The thermostat (it is jammed watch chapter of the cooling system, heating).

Heater

The fan of the heater does not work

1. The protection device of the motor of the fan is wrong. Check the protection device of the fan, replace if it is necessary.
2. It is the fan switch incorrectly. Check whether Vorresistoren effort is used, be lowered and check the fan switch.
3. It is the electric motor incorrectly. Check whether the effort at the made ignition and the closed fan switch is used to contacts of the motor of the fan. If the effort is used, replace the motor.

The fan of the heater does not work at one of steps

The heater is not excluded by the regulator

1. It is the switch incorrectly. Check the switch.
2. Rope regulation of smessitelnoj saslonki are damaged or badly mobile. Replace a rope.

Too low power of heating

1. Too low level of the cooled liquid. Check the level of the cooled liquid if dolejte is necessary.
2. The control unit of the heater has the heavy movement, is wrong. Check the heater control unit, replace a rope if it is necessary.

Noise in the field of the heater fan

1. It is dirt, leaves get. Accept the fan and you clean it, you clean a wind tunnel.
2. Frustration of kryltschatki, defect of the camp. Accept the fan motor, check ease of the movement.

Automatic transmission (AT)

Common problems which are connected with functioning of the mechanism of switching

1. On number of refusals which are connected with violation of regulation of a draft of switching it is possible to give the following:
      a) if the start of the motor at provisions of the transmission other than "R" is possible (parking) and "N" (Nejtral);
      b) if statements of the indicator of provision of transmission differ from really chosen transfer;
      c) if the car at transmission which is defined in situation "R" or "N" moves;
      d) if transfers switch hardly or as much as necessary.
2. Make gear shifting draft regulation (it watch chapter of a box of gear shifting).

probuksowywajet transmission, hardly switches, transfers minor noise or does not guarantee the movement of the car at the device on one of halls or the reverse gear

1. The mass of the possible reasons of the problems listed in heading exists, however, only one of them - the wrong transmissionnoj level of liquid gets under competence of the fan of the mechanic.
2. Before banishing the car in a workshop of car service you check the level and a condition of transmissionnoj of liquid (watch chapter Routine maintenance). Correct level according to requirements of specifications) or replace liquid together with the filter. If the situation did not improve, ask for the help experts.

Take a blank space of transmissionnoj of liquid

1. AT liquid has dark red color. The trail of its vytecheniye does not need to be fouled it is necessary with traces of engine oil which can be carried away on air current hinzurennenden transmission karter.
2. For tracing and localization of a source of Ausfließens you delete from the transmission boat all traces of dirt and Schmierens first of all. You are good coming nearer obesschiriwatelem from und\oder you make steam cleaning. Then you make by car a short trip at a small speed (at the same time traces of Ausfließens did not agree from current hinzurennenden far from its source). Stop, the car and by means of audit visualen you establish to poddomkratte Ausfließens source. Mostly meet as it:
   
      a) You pull a transmission kartera peel, - bolts of underground mining firmly of und\oder you replace transferring of a peel;
      b) students of gas station of liquid, - you replace a rubber condensation on the place of an entrance of the listener to transmission karter;
      c) You tighten the transmissionnoj lines of liquid, - or you replace with schtuzernyje of association lines;
      d) the listener of ventilation, - it transmission is crowded with und\oder water got to them.

Oil has brown color or smells of the fire
