Problem diagnostics

In case of infringement of functioning of system of preheat search of the reasons is usually made by substitution instead of a checked component of another, obviously serviceable. There is also a possibility of performance of several preliminary diagnostic checks (see further).

 PERFORMANCE ORDER

1. Connect the voltmeter or a lamp-sampler on 12 In between a wire of giving of a food on candles накаливания and weight (metal of the power unit or a car body). Track, that there was no short circuit of electroconducting of a food on weight.
2. Ask the assistant to include ignition and make sure of serviceability of giving of a food on candles. Fix duration of the period of operation of a control lamp of system and time during which candles remain energised. Switch off ignition.
3. At air temperature in an impellent compartment 20С the control lamp should remain included during 5 6 seconds. On the expiration of stipulated time a food continues to move on candles during about 10 seconds. With fall of temperature duration of burning of a lamp increases, and on the contrary.
4. If a food does not move, it is necessary to check up a condition of the relay of system of preheat and connecting electroconducting.
5. For revealing of a defective candle накаливания execute following actions: on equipped турбокомпрессором models remove the built in cooler (Intercoоler), on models without a turbo-supercharging with engine D9V remove a casing воздухораспределителя. In case of need remove an inlet air line and disconnect a ventilating hose from a jellied mouth of impellent oil. The Power supply system - diesel models more in detail see. Give fixing nuts, clean washers (if they are provided), then disconnect from candles the main submitting wire () and power supplies tyre. Try not to drop a nut and a washer.
5. By means of connected to the positive plug of the battery of an ohmmeter or a lamp-sampler on 12 In check up conductivity presence between the plug of each of candles накаливания and weight. Resistance of a serviceable candle should be very little (less than 1 Ohm), therefore, if the lamp-sampler does not work, or the ohmmeter fixes higher resistance, the corresponding candle is subject to replacement.
7. In the presence of possibility of use of the ampermeter it is possible to make check of the current strength, proceeding through each of candles накаливания. After initial jump in 15 20 And, value should be stabilised around 12 And. Otherwise the corresponding candle is faulty and is subject to replacement.
8. In summary remove candles and make visual check of their condition (see further).
