A car Chevrolet lanos produced and assembled since 2004 in Ukraine at the Zaporozhye Automobile Plant. This model- revised version Daewoo sens... Few differences still exist in Chevrolet Lanos picking... The shape of the rear fenders, the look of the trunk lid, the radiator grille, as well as the interior handles, door trim and rear lights, and other small details have changed.
Breakdowns in a Chevrolet Lanos car
But the car, like other types of transport, can fail. Let's consider in detail the breakdown of the gas pump.
The moment we start the car, we always hear the sound of the fuel pump functioning. Then he raises the pressure in the fuel rail, and the electrical unit turns it off. Then the fuel pump turns on by itself, only when the engine rotates. When the sensor crankshaft begins to transmit pulses, voltage is applied to the coil, this is what contributes to the supply of voltage to the electric motor.
In the event that you do not hear the sound of a working gas pump, then it is likely that the gas pump does not work in the Chevrolet Lanos. In order to make your own check, you need to perform several steps.
- Raise the seat in the back (from the passenger side).
- We see a hole in the flask, carefully remove it.
- We direct the hole with the contacts towards ourselves.
- We connect a special tester to them. We start the car and check for voltage.
If there is still tension, then it will be necessary to relieve fuel pump and apply voltage to the terminals of the engine from the battery, in order to once again verify the breakdown. But if there is no voltage, then you need to remove passenger seat front and inspect the connector of the C301 plug. Its contacts are often oxidized.
It is also possible that the fuel pump does not work because of the fuse in the Chevrolet Lanos. Where the fuses are located is easy to figure out. We open the hood, inspect the general condition of the fuse. If everything is normal with him, then another detail is to blame for the pump breakdown.
For those who are not strong in technology, if the gas pump does not work in the Chevrolet Lanos, the diagram can help you figure out clearly how to check, and also tell you where and what part is located. To do this, you need to find a schematic diagram of a Chevrolet Lanos car on the Internet. Or you should choose the simplest option - contact a car service to a specialist.
Head lighting passenger car Chevrolet Lanos, before starting the trip, must be in good condition, since the driver is obliged to turn it on not only in dark time days, but also during the day, to indicate the dimensions of your car. Most often, on a Chevrolet Lanos, malfunctions occur in the low beam electrical circuit.
If only one dipped beam headlamp does not light up, then troubleshooting usually begins with checking the condition of a halogen lamp with two tungsten filaments. Possible malfunction the filament of the dipped beam may burn out, under which there is a small reflector that directs the beam of light to the upper part of the headlamp reflector. If this thread is burnt out, then you will have to purchase a H4U halogen lamp (60/55 watts), but when installing the lamp, remember not to touch its bulb, since after turning on the head lighting it will fail due to overheating.
When, when checking, it turns out that the dipped beam thread has not burned out, then you will have to open the cover of the mounting block located under the hood of the car next to rechargeable battery and check the condition of the fuse protecting this electrical circuit. If the dipped beam in the left headlight does not light, then check the ten amp fuse Ef11, and if the dipped beam in the right headlight does not light, then it is necessary to check the fuse Ef12 (10A). Location of fuses in mounting block You will be prompted by the pictogram diagram located on the lid. If it turns out that the lamps and fuses are in working order, then you will have to ring the wires coming from the fuse to the lamp holder, for a break or lack of contacts in the plug connectors.
It is also possible that there is no dipped beam, in both headlights at once. The likelihood of simultaneous burnout of the lamps is not so great, so you need to start troubleshooting with the mounting block. First, we check if the fuse Ef19 (10A) is intact, since it is through it that voltage is supplied from terminal 30 of the ignition switch to terminal 30 of the dipped beam relay. And after the contacts of this relay are closed, from its terminal 87, the voltage is supplied to the fuses Ef11 and Ef12, through the low-beam, high-beam steering switch.
This relay may not work for two reasons: either voltage was not supplied to its terminal 85 from the light switch, which should be set to the second position, or the movable contact has broken, which does not close contacts 30 and 87. In the first case, you will have to check the condition of fuse F2 located in the mounting block in the passenger compartment on the left sidewall in the area of the passenger's feet and the light switch. In the second case, the dipped beam relay will have to be replaced.
Some Lanos car owners have encountered such a malfunction as the car does not start, but the check does not light up. What are the reasons for this effect, as well as methods for eliminating the problem.
Why won't the engine start?
To identify problems and reasons first you need to understand what works and what doesn't ... So, we turn the ignition key and try to turn the crankshaft. If we are talking about this particular problem, then the starter will twist, but the ignition of the air-fuel mixture will not.
The cause of this malfunction must be sought in the following systems:
- Fuel line and its elements.
- Ignition system.
- Air supply system.
- Electronics.
Elimination methods and diagnostics
Now that the causes and possible systems have been found, where the problem will lie, it is necessary to carry out diagnostic operations and find solutions.
This will require a toolkit, as well as knowledge of the Chevrolet Lanos design.
It is worth warning right away that there is a car enthusiast who does not know how his car works, then he has a direct road to a car service. So, let's look at the sequence of actions that will be aimed at fixing the problem and returning power unit the same qualities.
Gasoline pump
Dirty fuel pump. Dismantling process for diagnostics and recovery.
It is worth starting by checking the performance of the gasoline pump.
So, for this, it is necessary to turn the ignition key to the first position and listen to if there is a characteristic noise of the unit operation. If there is none, then for sure there is no fuel supply to the combustion chambers, and it is worth checking the part.
Diagnostics and removal
In order to carry out diagnostic operations, the fuel pump will have to be dismantled from the car.
After that, it is worth connecting the fuel pump directly to the battery to close the circuit and see if it works. If there is no reaction, then it is worth replacing the part with a new one.
Nutrition
If the fuel pump has reacted, then there is a malfunction in the supply of current to it.
The next step is to check the power supply. In the mounting block, it is worth inspecting the fuse, if it is intact, then you need to look for a wire that is out of order.
Diagnostics must be carried out according to electrical diagram, which not everyone has. If a wire is found, then it should be replaced with a new one. But motorists tend to isolate the contacts.
The process of diagnostics and cleaning of injectors at the stand. Different states of the injectors.
Injectors
Another place in fuel system, which can directly affect the start of the engine, become injectors. So, a breakdown can give too much fuel, or not at all. In this case, the motor will not start. To diagnose and eliminate the malfunction, you will have to dismantle all the nozzles, and then check them on a special stand. If possible, clean, or even better, it is recommended to replace the old ones with new ones.
Mounting block with fuses and relays.
No spark
If a malfunction is not found in the fuel system, then it is worth understanding why there is no spark.
In this case, there are not many options - candles or high-voltage wires are out of order.
Dirty spark plugs.
The motorist should unscrew the spark plugs and visually inspect them. As a rule, faulty injectors simply flooded them, as a result of which the spark disappeared. But, also the reason can be hidden in the very candles. If the parts are visually clean and not damaged, then you should go further.
High voltage wires
BB wires are marked with arrows!
The next step is to check high-voltage wires.
So, to carry out diagnostic operations, a multimeter is needed, which is used to "ring" each product. Normal resistance should be around 5 ohms.
Air supply
Clogged air filter.
The first two necessary components in order for the car to start have been checked - fuel and spark, now it is time to diagnose the air supply system.
First of all, you need to check condition air filter ... If the element is too forgotten, there is not enough air in the combustion chamber to form an air-fuel mixture, as a result of which the spark plugs are flooded.
The second element that will prevent the launch is throttle ... It is necessary to check in what position it is located and it opens at all. Then, it is recommended to dismantle and clean it. This is done with carburetor cleaning fluid.
Electronics
If we talk about the electrical part, then first of all it is worth checking the engine sensors, which are responsible for starting the motor. Often the reason that Lanos grabbed and stalled are sensors and regulators. So, it is worth checking all the meters that affect the starting of the motor and its normal functional operation. Namely:
- Coolant temperature sensor.
Coolant temperature sensor removed from engine.
- Knock sensor.
Knock sensor removed from the engine.
- Idling regulator.
Idling regulator.
- Mass air flow sensor.
Electronic engine control unit connected to the vehicle.
Well, if the previous diagnostic and repair operations did not help, it is worth looking for the problem in the electronics, namely in the electronic engine control unit. It was this detail that did not show the check when turning the key and does not allow the motor to start. To eliminate the malfunction, you will have to connect to the ECU and carry out computer diagnostics... Surely errors have accumulated that block the normal operation of the entire system.
conclusions
If the Chevrolet Lanos does not start, the check does not light, there is no spark, it seizes, but does not start, then malfunctions may lie in three interconnected systems - air supply, fuel and spark. If the above methods did not help, then it is worth contacting a car service, where they will establish the cause. Ultimately, these can be burned-out valves or worn-out seats that pull back exhaust gases.
The first Lanos were from Korea and these models are more reliable and of better quality than those already produced in Ukraine (SKD began in 1998). Since 2000, the production of Daewoo Lanos also began in Poland and they say that the quality is somewhat better than Ukrainian, but in 2008 the Poles stopped production.
The quality of Lanos, in principle, is tolerable, but still there are nodes that require special attention, so to speak weak spots, because they are prone to the most frequent breakdowns.
Engine
- The jagged one ends at 70-80 thousand.
- After 60 thousand mileage, in order to avoid breakage, you need to replace drive belt generator.
- Injection system sensors fail: absolute pressure, position throttle or lambda probe.
- buggy for no apparent reason.
- The cylinder head gasket often leaks.
Transmission
- The checkpoint buzzes a lot, if you don't change the oil by 70 - 100 thousand.
- Clutch in frequent boxes serves up to 50 thousand
- can misalign for no reason, the plug fails.
Undercarriage
- There are many complaints about the work of standard shock absorbers.
- Frequent malfunctions of the steering rack - leak, hum, knock.
- Failure.
- can crunch already at 20-25 thousand km.
- If you do not change the ball joints every 60 thousand kilometers, they can break "without warning."
Electrician
- Not a high-quality engine compartment wiring harness - the electrician is buggy.
Cooling
- Unreliable radiator of the engine cooling system - leaks.
Brake system
- If the liquid in brake system did not change more than 30 thousand km. brakes become ineffective.
Salon
- Rear-view mirrors fall off.
- The blower mode switch breaks.
- The clock falls out of the center console.
- The wiper mechanism refuses.
Body
- Sometimes badly pasted rear glass- flows.
