Why on Daewoo Nexia burns. Subtleties of repair and replacement of the contact group of the ignition lock on DEU Nexia. Check Engine: General conclusions for Daewoo Nexia

The car of the Korean manufacturer is popular among motorists. Daewoo Nexia is a comfortable and practical vehicle for the city. But, unfortunately, there are no ideal cars, everyone has its weaknesses. In Nexia is a group of contacts in the ignition switching lock. She often fails. In the article, we consider why the contact group is burning, how to repair and replace what to do to make the item not burning in the future?

What does the contact group of the ignition lock look like

This item is located in the ignition lock. When turning the key, it is responsible for the flow of current to the starter and the power supply of other elements of the car: Magnetites, fan stove. In Daewoo Nexia, a design solution is used, which, according to experts, is difficult to be called successful.

Consider the contact group more closely. In the plastic case of two parts, electrical contacts are placed, they are switched depending on the position of the key.

The contact group in the Korean car often flashes due to an unsuccessful design solution

Nexia group has 5 conclusions:

• "30" - the power supply from the battery is supplied;
• "15" - the ignition circuit;
• "15a" - chain of the fan stove;
• "50" - the output to the starter;
• "KA" or "KB" - a chain of a regular radio.

Causes of burnout and symptoms

Strong current passes through the ignition castle. As a result, the wiring is very heated, the contacts are melted. A large load occurs when the engine is started, most of all suffer the conclusion marked "30". He first does not withstand, the plastic case near the contact melts.

Due to the current of a large force, which passes through a group of contacts in the ignition lock, the contacts are very hot and the plastics housing is melted.

In most cases, the burnout of the contact group is manifested as follows: after turning the key in the lock the starter does not twist. When driving manifests itself as follows: Suddenly, the engine is stall, the instrument panel goes out and the smell of burnt plastics appears in the cabin. The second sign of the breakdown is a non-working standard radio.

It is impossible to say that the starter does not spin and car does not work only because of the contact group, but in 90% of cases for DEU Nexia symptoms are supposed.

How to check and make repairs

Check the health of the contact group in the ignition lock under the power of any motorist. Performance is determined by the appearance of the plastic case and the presence of carbon on contacts within the group. To get to the details, it is enough to armarate with cruciform and straight dumplings.

If the housing is not damaged, then be sure to inspect the internal contacts. To do this, carefully disassemble the case. When you detect in Nagar, remove it using a sharp knife or dug. Such a temporary procedure will help on the road. For the first opportunity, contact your electrical station to the electrical station or replace the contact group with your own hands.

Eliminating the cause of burnout

It should be noted that the replacement of the contact group helps for some time. For quality repairs, it is necessary to eliminate the cause of burnout: reduce current load on contacts. Strengthening the weak point of Daewo Nexia can be installed additional relays according to the scheme:

When using two relays, the load on the contact group decreases by two times

This method will help extend the service life of the contact group by more than 2 times. To improve the electrical chain of the ignition of the Korean car for anyone.

For the completeness of understanding the process of replacing the contact group in Daewoo Nexia, watch the video:

Independently performing the repair of the contact group on the car Daewoo Nexia will not be especially difficult. Additional difficulties will arise if the wiring is replaced. Frequently melted wires that goes to the contacts "30" and "50". If possible, unload the contact group. This will protect the car from fire and extends the service life of the part.

Oh, how much you need to tell you.

Acquisition

Buying a car is always a pleasant action, but only if it is accompanied by a more convenient, "nervous" and high-quality operation. Consider today a real folk car, which is very good in the "zero" entrenched in the Russian Federation in his niche and kept this position for many years, giving fire to AvtoVAZ.

We are talking about Daewoo Nexia New (N150). The car was taken in oil, that is, straight from the factory, at the time of her inspection a month passed, as she descended from the conveyor. As it should be purchased - it is always a lightweight euphoria :). From the moment of order, before receiving the long-awaited. I arrived in the salon, went to the manager, he greeted and spent to the car. The first inspection was good, everything worked, no statement was found. Paying the rest of the money, I received long-awaited documents and keys)).

The first trip. "Receipt"

With a more thorough inspection, a small church was caught on the body, he was very small, but not very pleasant ... The main master immediately jumped with a jar of paint and quickly mandated with a brush, did not run on them, but nothing will understand anything and It does not particularly depend on them.
He left the cabin, everything was fine, nothing, as they say, did not foretell trouble. I drove to refueling (oil magicians * trawl, I do not advise you to refuel on them) next to the salon (in the salons, very little petrol gasoline, right, why they can be broken) and went closer to the house, which is 25 km away from the place of purchase. Here and the first "dances" began. 20 kilometers, "Check" caught fire. What could be the problem, naturally, it was very difficult to understand ... Uncle (well understands in cars) I could not do anything, the warranty service was very strongly reversed. In the service where I came under the guarantee, just threw off the "Check" (they said that the new nexi diseases on gasoline), but taking off 20 km, "Check" caught fire again. At the second arrival had already made diagnostics (!) (For the first time, it was apparently in scrap was to do) and found out that the Lamb probe was not working. We were lucky that under warranty, the price of a lemb probe, at that time, there were about 15 thousand rubles, plus four candles. The cause of everything was poor-quality gasoline, which was flooded at the first refueling. While I traveled with "Chek", it seemed to me that I had a very high consumption. By doing simple measurements, I was horrified, in the fall of Nexia "Kushal" 14-15 liters per hundred (!) (As if I had a three liter engine).

Fall. OMYVIKA

Autumn came on the yard, slush is the first signal that it is time to use wipers. A 2 liter of fluid was flooded in the washer tank and after a half-hour trip, the washer light lights up (I could not pour 2 liters of liquids for half an hour). It continued for a week until I realized that the liquid simply follows. The service said that the engine housing (for overhanging the wasyavki) is cracked. So I mean that he was originally cracked, from the factory, or he was replaced in the cabin (dealer salons often produce a substitution of parts, setting knowingly Chinese or defective). He was also replaced by warranty. I liked the fact that the service did not arise any questions and all immediately changed. The only minus is the expectation of the details, on average 14 days.

Spring. Gur

Winter car departure well, and especially started! As there, in advertising, it was said: "I love Uzbeks. They are good in winter, "I can confirm on all 100! With minus thirty, the machine served visual sounds from 2-3 times the scroll of the starter. I remember somehow came out of work (there were about 27 * frost), looked at how everyone was pushing and towed her cars, sat down, started, warmed and drove)). Spring came, the car behaved well on the road, but in the rear wheel (so it seemed to me) the sound of rubbing the tire on the arch was appeared, it was always when turned. I tried to find traces visually, but without successfully, nothing was visible. After writing in the service, I decided to ride a little more, but in the end it came to the fact that the steering wheel turned, as without GUR and immediately became clear because of what it was all. The service was not allowed to drive the car with its own way and a tow truck took me. All services were at the expense of the dealer, the tow truck costs 4 thousand rubles. The cause of this problem was the cracked hose, through which, when turned, a liquid was flowing for the power of the steering wheel (here's where this sound was, very similar for friction). After that, an externally engine began to resemble the car of the 90s, this fountain of oil flooded the entire engine. On this, in the coming year, "dances with a tambourine" ended.

Summer. Cool

Remember the heat which was in the central part of Russia (and not only)? After this heat and got out a new problem. The machine is cooled well, no problems arise, even in a strong bake. Somehow, after the stop, I decided to look under the hood and noticed an interesting picture, with the middle of the tank "cooled" the same fluid bubbles. Maybe during the heat burst or was already defective who knows him, but under warranty everyone was very well drained, replaced and poured.

Podiatog

On this, all the "dancing with a tambourine" and ended, thank God! Although it was enough. The car is now driving on the roads of Russia and does not create special problems, things come out on the little things, which should come out during operation. At the end of the warranty service, I changed the maximum under warranty, including all plastics in the cabin, which managed to lose their trade look. For its class, the car is good, but the restyled version could do and on the most modern: the pillow and the like little things.

Outcome

With this machine, I learned all the difficulties of ownership of the car, got the experience of buying a car, almost was deprived of rights (for railway. The court returned) and arranged the first accident during parking (prorter former colleague). As far as it is reliable, it is hard to say, since I did not own the Zhiguli, Flood and other domestic cars. At the very least, the familiar Nexia of the previous release rolled back 100 thousand, changing only oil. Now it is no longer going.

P.S. But I liked the car))

Especially for cadabra.

The appearance of the engine error icon (Check Engine) on a number of Daewoo models, including NEXIA - the situation is quite common and can be dictated by a large number of reasons.

Some of them can seriously affect the performance of the power unit, while others be invisible. However, regardless of the cause of the occurrence of an alarm, it makes sense to immediately address it.

Check Engine Error - How to determine the cause of the signal appearance?

Immediately, we note that it is almost impossible to diagnose the reason for the appearance of the signal on the dashboard without the presence of an on-board computer. If the BC is installed, it is possible to directly view the information and engine error codes. If it is absent, the only way is the engine diagnosis at the service center.

In the diagnostic process, the master through a special service connector connects a computer with special software that retrieves and visualizes information from the memory of the Daewoo Nexia electronic control unit.

The simplest case

Separately, it is worth saying that the appearance of Check Engine can be associated with the usual failure of electronics, poor-quality fuel and other causes. In this case, you can try to "reboot" the electronic unit, removing the negative terminal from the battery for 10 minutes. If the error has not disappeared, this means that the diagnosis is still necessary.

CHECK Engine caught fire: List of the most common faults

As a rule, the following faults become the reason for the Check Engine indicator:

1. Error in the work of the lambda probe (oxygen sensor). This sensor is responsible for analyzing the amount of oxygen in the exhaust gases of the car, adjusting the fuel supply accordingly and providing optimal fuel efficiency parameters. The cause of his breakdown can be a large number of factors - from technical defects to low quality gasoline. If the error codes are shown on its malfunction, the sensor requires replacement. It should be remembered that the sensor should be replaced, since a change in its malfunction can cause a premature failure of the catalyst - a very expensive element of the exhaust system.
2. Breakdown in the catalyst. The catalyst is responsible for the purification of exhaust gases and the correspondence of the Nexia car with modern environmental standards on the emission of CO. The reason for troubleshooting becomes, for the most part, the low quality of domestic gasoline and the late passage of regulatory items. The catalyst itself is quite expensive, and some motorists resort to its removal by installing "deceiving" - a self-made device at which the "check" does not light up. It is not recommended to use such a tricks in view of the difficulties that may occur during the passage of the state technical inspection (the content of harmful substances in the exhaust will increase dramatically).
3. The failure of the mass flow sensor air flowing into the engine injection system. Such a breakdown leads to interruptions in the operation of the power unit caused by the depletion or enrichment of the mixture and is accompanied by "floating" turns, jerking the car in motion, etc.
4. Failures in the work of spark plugs or wiring. Interruptions associated with wear and failure of high-voltage wires and candles are often accompanied by an engine error output.

These reasons are the most common cause of the indicator's operation, however, they are far from the only one. On the 8-clapped power unit Nexia with a working volume of one and a half liters (as well as on CHEVROLET LANOS / ZAZ CHANCE vehicles with the same engine), there are no cases when the "Check" lights up when running 10-15 thousand kilometers. In this case, the error code flashes the crankshaft sensor fault. In practice, no sensor replacement in this situation is required, and failure is caused by errors in the standard software of the electronic control unit. They are eliminated by flashing the ECU using the appropriate software. However, it is possible to implement this procedure only in the service center.

Another reason for the appearance of an "alarm light bulb" can be extremely simple, but the factor is not obvious for the car enthusiast - a decrease in the tightness of the fuel system caused by ... a loosely twisted lid of the gas tank. For this reason, you should always screw the lid before the safety "ratchet" is triggered.

Check Engine: General conclusions for Daewoo Nexia

As we see, the reasons for the appearance of errors in the engine on this model Daewoo there is quite a lot, but all of them are inherent in one degree or another, all cars with the fuel injection system. At the same time, it is worth paying properly, cases of serious malfunctions associated with the engine, in Nexia is quite rare. It is due to the reliability of the power unit leading its "story" since the beginning of the 80s of the last century.

By the way, the owners note that precisely 8-valve engines differ in particular reliability in operation, and the 16-valve versions are somewhat inferior to them according to this parameter.

In particular, these motors suffer from a serious disadvantage of oil from under the valve cover when running over 50 thousand kilometers.

Despite all the above nuances, the appearance of the Check Engine alarm is a serious occasion for checking the engine performance. Ignoring the alarm can lead to serious malfunctions, and in some cases and to the overhaul of the motor.

For this reason, the owners of nexies make sense to recommend installing a side computer that allows you to quickly obtain information about error codes and, accordingly, take timely measures to troubleshoot. This path looks the simplest, because today there is a large selection of onboard computers for various models of Daewoo.
