GW Hover. Unexplained fault


Last week I tested the updated Chinese SUV Great Wall Hover H5. This is already the third generation of Hovers. I was frankly impressed at the pace at which the Chinese are gaining experience in building cars. I immediately remember our dear AvtoVAZ, which has been riveting the same parts for decades, without improving characteristics or correcting obvious errors.

So, classic rear-wheel drive frame SUV with a rigidly connected front axle, a 2.4-liter gasoline engine and manual transmission transmission Hover H5 is the first Chinese SUV that has been certified according to EU requirements and has received the right to enter the market of more than 22 EU member countries.

For rides, I chose the motocross track on Michurinsky Prospekt; after the rain it becomes especially interesting.


2. Great Wall Hover has been produced since 2006, and the updated third version appeared in 2010. Over the past 5 years, the design of the car has been significantly improved, and the most important thing is that the Chinese do not stop there, but continue to improve the cars they produce. So, for example, quite recently there appeared Hovers with automatic transmission and diesel engine. Since 2011, the Great Wall Hover H5 with a gasoline engine has been assembled in the town of Gzhel near Moscow.

3. When viewed from the front, Hover is now very reminiscent of the Mazda CX-7, which does not quite fit with its brutal character. And the remote plate for the license plate is located too low - in the photo the license plate is still in place, but after the nearest ford it moved under Windshield.

4. In profile, the silhouette has remained virtually unchanged, and of course the door handles from the 90s are begging to be replaced. At the rear, LED optics are now used (dimensions, brake lights, fog lights).

5. The interior is very reminiscent of that in the Mercedes ML, a particular similarity is noticeable in the central air vents. Pay attention to the presence of airbags; Hover received 4 stars according to the results of independent crash tests.

6. Under the hood is a 136-horsepower gasoline engine. Mitsubishi engine MIVEC 4G69 S4N deformed to Euro-4 standards.

7. I won’t bore you with photos of the exterior; fortunately, updated Hovers are no longer such a rarity on the streets of Moscow, so I suggest you take a closer look at the insides of the car.

8. Leather steering wheel with multimedia system and telephone control buttons.

9. Leather interior included basic equipment. The leather is not real, but it is thick and easy to clean. The seating position in the updated Hover has changed; with a height of 180 cm, I now almost rest against the ceiling (one should also take into account the presence of a hatch that conceals useful centimeters under the roof).

10. The two-way acoustics surprised me with the sound quality, clearly superior to the class of the car.

11. The driver's seat is electrically adjustable. Please note, left-hand side The buttons for adjusting the position of the seat cushion move up and down, but such adjustment is not structurally provided.

12. And now attention - automatic windows implemented on three-position buttons. Korean and Japanese engineers should choke themselves from the greed with which they still “delight” buyers of new cars with, at best, an automatic mode for the driver’s window and, in special cases, for the front passenger. But the Chinese overdid it with the automatic closing of the doors when driving - if you press Unlock at speed, the car will instantly close them again. It is very annoying when driving off-road, where you often need to get out of the car.

13. Control unit for mirrors, fog lights and backlight brightness dashboard.

14. Dashboard. On new cars with automatic transmission and a diesel engine, a monochrome LCD screen is installed at the bottom center. By the way, interesting feature- there is no such thing as a stabilization system on Hover.

15. Single-zone climate control. Below is the control button for the connected drive. To engage a downshift, according to the instructions, you need to hold the clutch depressed for at least 5 seconds. Classic party time with button control.

16. White LED lights devices (another stone for the Koreans with blue lighting - they're sick of it). By the way, it is especially worth noting the rear view camera, which works very well in the dark - apparently one of the best examples from dieextream :) The multimedia system is included in the basic package; it can be controlled either by buttons or via the touch screen. There is a speakerphone.

17. The gearbox is five-speed; cars with automatic transmission have recently appeared. Previously, the Chinese did not have them at all.

18. Central tunnel, compartment for small items, control buttons for heated seats.

19. There is a USB connector and a line input in the armrest.

20. The Hover even has a rain sensor, although the engineers forgot that the wheel for adjusting the frequency of operation of the wipers in intermittent mode is also relevant for cars with a rain sensor.

21. Well, the light sensor is also available (they are located in the same module). And one more cobblestone for Koreans - the turn signals flash three times when touched lightly. It was a complete surprise to see this on a Chinese car.

22. Folding ignition key with alarm control buttons and “Panic” function. In general, the Chinese are good at messing around with electronics. For example, this is the first car in my memory that closes the hatch on its own after removing the key from the ignition and opening the driver's door.

23. It’s really not worth betting Baby chair on driver's seat. There is the same sticker above the passenger seat, are Hovers still available in right-hand drive, and are stickers placed on both sun visors for unification? :)

24. Let's move to the second row.

25. There is a lot of space, it’s comfortable to sit. There are even height-adjustable seat belts.

26. The Chinese have finally stopped using the trunk handle - under the thumb there is a button that activates the electric drive that opens the lock on the door. There is no direct mechanical handle in the niche.

27. Trunk.

28. Off-road testing was limited road tires- getting out of the rut was an almost impossible task. At the same time, in a rut in a low gear, Hover moved more than confidently. I was hanging on with my belly, but I kept going. I managed to land the car in a deep rut twice - once I got out of the swing on my own, another time I used a cable.

As for driving characteristics: The Hover has an independent torsion bar suspension at the front and a dependent spring suspension at the rear. For such a combination, the car steers very well, although the steering wheel is quite light and off-road this is more of a minus than a plus. It goes great on the highway at a cruising speed of 120 km/h, in the city you can drive faster than traffic.

In terms of comfort: Very positive impressions, especially in comparison with the previous model, although there are small complaints about the build quality - perhaps after the purchase it will require some minor modifications: press the seal here, tighten it here.

To summarize all that has been said, I would like to first of all mention the price of the car - just over 700 thousand rubles. IN maximum configuration with all the options listed above. The result is an ideal utilitarian car for those who value practicality rather than show-off.

The Chinese are still great - they learn very quickly from their own mistakes, correct, improve and refine. At this rate, in 5-10 years their cars will seriously displace the largest automobile brands.

Instrument panel option No. 2.

For gasoline engine

For diesel engine

1 - Interior door open warning light This warning light lights up if the side door of the car is open or not tightly closed.

2 - Tailgate open warning light This warning light comes on when the tailgate is open or not properly closed.

3 - Oil pressure warning light Lights up when the ignition key is turned to the “ON” position. After the engine starts, the light should go out. If this light does not light up when you turn the ignition key to the “ON” position, this means that the light bulb or fuse has blown. In this case, it is necessary to check the system and eliminate the malfunction. If the light randomly lights up briefly while the engine is running, this does not mean a malfunction in the engine system. If the light is constantly on while the engine is running, it is necessary to turn off the engine to identify and eliminate the malfunction. One of the reasons why the oil pressure warning light comes on is that there is insufficient oil in the engine.

Attention! If the engine is not turned off in a timely manner while the emergency oil pressure light is on, serious damage to engine parts and mechanisms may occur.

4 - ABS anti-lock braking system warning light (if the vehicle is equipped with ABS)

The yellow ABS light is designed to control the control of the vehicle's anti-lock braking system. When the ignition key is turned to the “ON” position, this light comes on. After the engine starts, the light goes out (if the light does not light up, contact your nearest Great Wall service center). If the light periodically lights up or lights up continuously while driving, you must stop the car, turn off the ignition, and then start the engine again. Then gradually accelerate the car to a speed of 15 km/h. If the light stays on continuously or comes on intermittently while driving, the ABS system needs to be checked.

In the event of a malfunction of the ABS system, the hydraulic brake system continues to function.

5 - Warning light for unfastened seat belt. If the seat belt is not fastened when the ignition key is turned to the “ON” position, this light will come on and go out when the seat belt is in the fastened position.

6, 9 - Turn signal indicator lights. Green turn signal indicators are located on the instrument panel. A flashing indicator means that the rear and front left or right turn signals are turned on simultaneously. If the indicator light flashes too quickly or does not flash, you need to check the light bulbs. If the indicator does not light up when you turn on the turn signal, check the fuse, bulbs and relay. When the hazard signal is activated, both sides of the turn signal indicators will flash.

7 - Brake system fault warning light

8 - Indicator light for high beam headlights on. When this indicator turns on, it means that the car's headlights are on in high beam mode.

10 - Warning light for battery charging system malfunction. When you turn the ignition key to the “ON” position after starting the engine idle speed The power supply from the generator starts and this light goes out. If the light comes on for a long time while the vehicle is moving, you need to check the battery charging system. Otherwise, it may be completely discharged. It is necessary to check the generator drive belt for possible looseness or breakage.

11 - Airbag warning light

12 - Brake system warning light. Lights up when you press the brake pedal.

13 - Signal light for all-wheel drive on. If, when turning the ignition key to the “ON” position, the lever transfer case is set to the all-wheel drive position (lever position “4H” or “4L”), the “4WD” warning light on the instrument panel lights up. When the transfer case lever is switched from the “4H” position to the “2H” position, the four-wheel drive warning light goes out with a slowdown; in this case, maintaining uniform straight-line movement of the machine, you need to lightly press the gas pedal several times.

14 - Warning light for low brake fluid level. If this warning light comes on when you turn the ignition key to the “ON” position, this means the fluid level in the brake system is too low.

15 - Warning light for open hood. This light comes on when the car hood is open or not closed tightly.

16 - Indicator light for switched on lighting. This light comes on when the headlights, turn signals and side lights are turned on.

17 - Parking brake warning light. If, when turning the ignition key to the “ON” position, the parking brake, the parking brake warning light comes on and goes out when the parking brake is released.

18 - Signal Light " Check engine» (check engine). The electronic engine control unit controls the fuel supply to the engine, controls the ignition and ensures that the exhaust characteristics meet the requirements of safety standards environment. When the ignition key is turned to the “ON” position, this light comes on. After the engine starts, the light should go out. If the light comes on while the engine is running or while the vehicle is moving, this means that there is a malfunction in the vehicle's engine management system or that one of the sensors has malfunctioned. In this case, contact your nearest service center.

For vehicles with a diesel engine equipped with a BOSCH electronic fuel injection control system with on-board diagnostics:
If you turn the ignition switch to the "ON" position and then return it to the "ACC" position without starting the engine or remove the key from the lock, the indicator will remain on for approximately 60 seconds. (specific time is determined by the central electronic unit control), after which it goes out.

or

Coolant temperature gauge. When the ignition key is turned to the “ON” position, the coolant temperature sensor displays the current engine temperature. " WITH" or " L" means the engine is cold. " N" means the engine temperature is too high. Normal operating temperature - indicator in the middle part.

20 - Warning light for coolant overheating

21 - Tachometer

22 - Front fog lamp indicator

23 - Rear fog lamp indicator

24 - Tailgate glass heated indicator

25 - Speedometer

26 - Daily mileage counter. The odometer shows the total mileage of the vehicle and the length of a given section of travel.
Mileage: accumulated mileage (0-999999 km, step: 1 km), route length (0-999.9 km, step: 0.1 km).

27 - Button for resetting the daily mileage counter. This button is intended to switch the scale of the total mileage of the car and reset the scale of daily mileage.

28 - Warning light for low fuel level in the tank. When there is little fuel left in the car tank (about 10.5 liters), the low fuel level warning light comes on. In this case, you need to refuel the car. The fuel level indicator may also light up when there is more fuel left in the tank when driving uphill, downhill, during sudden braking, acceleration or turning as a result of fuel displacement in the tank. If the indicator lights up when driving smoothly in normal mode on a horizontal surface and there is sufficient fuel in the tank, you should have the vehicle checked by an authorized Great Wall Motor service station.

For vehicles with diesel engine: Fill the tank with fuel immediately if the fuel level indicator needle moves into the red range of the scale. To avoid accelerated wear and damage fuel pump high pressure, do not allow the fuel in the tank to be consumed to a level at which the engine turns off.

or

29 - Fuel level indicator. The sensor shows the relative amount of fuel relative to the total volume of the tank. When you turn the ignition key to the “ON” position, this indicator can be used to determine the approximate amount of fuel in the vehicle tank. When the ignition key is turned to the “OFF” position, the gauge arrow returns to the “E” (“empty”) position; this reading is insignificant.

Indicator preheating engine. This indicator lights up in cold weather after turning the ignition key to the “ON” position if the engine temperature is below the set value. After the engine heats up to the set temperature, the indicator goes out. The preheating system ensures stable engine starting at low ambient temperatures.

Indicator of excess level in the fuel separator sump. This indicator lights up when the water level in the fuel separator sump exceeds. In this case, it is necessary to stop the car, check the separator and drain the water from the sump.

Indicator electronic system distribution of braking force. This indicator is intended to indicate the state of the vehicle's electronic brake force distribution control system.
This indicator lights up after turning the ignition key to the “ON” position and after a while (1-2 seconds) it automatically goes out if no faults are detected in the system. If the indicator lights up continuously or does not light up at all, there is a problem with the system. In this case, the vehicle must be checked at an authorized service station.

If the brake force distribution system fails, the conventional hydraulic brake system continues to function normally, but in any case, the brake force distribution system must be inspected and repaired as soon as possible.

All-wheel drive indicator. The "4WD" indicator on the instrument panel lights up when the ignition key is turned to the "ON" position if the transfer case switch is set to the four-wheel drive position ("4H" or "4L").

Engine blocking system indicator. After turning the ignition key to the "ON" position, communication is established between the anti-theft device controller and the transceiver in the key head, as well as between the said controller and the electronic engine control unit. The indicator lights up while the password is being identified, i.e. for 2 sec. If the password verification is successful, the indicator goes off and the engine is allowed to start.

If the password is not confirmed, the indicator starts blinking at a frequency of 1 Hz, the fuel supply to the engine is cut off, and the engine cannot be started. In this case, you must also contact a service station.

Transmission fluid overheat indicator.

Indicator for turning on parking lights.

Reserved.

Overspeed indicator.* This indicator begins to flash when the vehicle accelerates to a speed of 120 km/h, and a short sound signal is issued to warn the driver that the speed is exceeded.

Fault indicator ESP systems. If the ESP system malfunctions, the indicator will remain on continuously. During normal ESP operation, the indicator may flash.

Automatic transmission oil temperature indicator (for vehicles with a 4D20 engine). The indicator lights up when the automatic transmission oil temperature exceeds 125°C. When the temperature drops below 125°C, the indicator will go out when the key is in the “ON” position in the ignition switch.

All-wheel drive indicator (for vehicles with 4D20 engine). The indicator lights up when all-wheel drive is connected.

Cruise control activation indicator. The indicator lights up when the cruise control function is activated by pressing the “CRUISE” key. When you press this key again, the indicator will go out and the cruise control system will turn off.

ESP system off indicator. The indicator lights up continuously when the ESP system is turned off.

Emergency indicator warning of the need for engine repair. This warning light illuminates when a fault is detected in any engine component not directly connected to the exhaust system.

Traction control system indicator*. The activation of the traction control system depends on road conditions. This indicator lights up automatically when the system is turned on.

This indicator lights up after turning the ignition key to the “ON” position and goes out after a while (1-2 seconds) if no faults are detected in the system. If the indicator does not light up, there is a failure in the system. In this case, the vehicle must be checked by an authorized Great Wall Motor service station.

To switch the display between trip meter and trip meter modes, press and immediately release the setting lever. To reset the route distance counter, press the adjustment lever and hold it pressed for a while.

I know from experience that the most unpleasant and time-consuming troubleshooting problems are “incomprehensible” faults. Such that when the owner of the car begins to list them, a feeling of unreality arises: “This cannot be!” Because illogicality creeps out of every word.


Well, judge for yourself, I’ll give you the latest example: a 2007 GREAT WALL Hover car. The problem began to arise gradually: a man was driving and was driving, and he wanted to lower the window, it was hot. Mechanically and without distracting himself from the road, he pressed the power window button and the car immediately jerked and stalled. He didn't understand. I looked at the instrument panel, everything was fine. It’s just extremely incomprehensible... the man started the engine again and drove off. And then he remembered this incident and told it to his friends as something extremely amazing: “This cannot happen, but it happened - now I’ll tell you...”.


And he would have forgotten about this incident, and would not have remembered it - if something similar had not happened again: he wanted to open the window, pressed the button, and the car stopped once. And here he was no longer surprised, but had to get nervous and think that perhaps it was time for him to go to a car service center and deal with this incomprehensible problem.


But in life, as it happens: “Until the roast rooster pecks.” And the fault inside the car lived and developed until another thing happened - incomprehensible, mysterious and disturbing: during the trip I pressed the brake, and the car just stopped and stalled... you release the brake, start the engine again - you drive as if nothing had happened . So the only conclusion is: “Go to a car service!” Hurry up."


From own Having experience in finding and eliminating such “mysterious” faults, I know that when a fault is labeled “incomprehensible, illogical, mysterious,” then the problem may lie in the car’s electrical system.


I always look with curiosity at the client to whom you tell about the cause of the malfunction, show its location and name the price for the work. Others wonder, why is it so expensive?..


“Expensive” is relative. I understand that everyone does what they do and wants to get adequate money for their work. And searching for an “incomprehensible, mysterious, illogical” malfunction is approximately the same as throwing a needle into a pile of sand on a KAMAZ, dumping this sand on the ground and saying: “Now let’s find this needle”...


Of course, I have certain and many years of experience in finding such faults, so I can show you where I started looking for the fault:




This is the driver's seat and everything around it. Why: this is where all the information and power circuits of the car pass. And when the malfunction is “incomprehensible and mysterious,” then one can assume a bad contact somewhere, a bad ground, and the like. How many contacts and connection points do you think can be located in the space shown in the photo above? Not ten, exactly. But the figure “one hundred or more” is closer to the truth. And each contact, connector, and connection point must be inspected, examined, and made sure it is working.


Unfortunately, at that time I had certain difficulties called “information hunger” and could not find a specific diagram of specific sections of electrical circuits. And this is not “amazing”. Probably only dealers can have full information, and we, private automobile entrepreneurs, have to somehow dodge.


However, it's not all bad. I know that the Legion-Avtodata company has been developing and promoting its Motordata program for many years. But I won’t lie: at that time I didn’t have the necessary electrical diagram of this car:




This scheme came to me later. And here’s what I thought: “if this circuit had been available at that time, then troubleshooting would have taken much less time.”


Well, I began to clarify the problem and look for this mystery in the appearance of the malfunction. I started with the ignition switch, then moved on to checking the fuses under the hood and the fuse box in the passenger compartment. Then the doors... burn...


There are different ways to determine a malfunction. In the initial training courses of the same Toyota it is written about them: “Checking for fragility... for bending... for vibration" And at some point I discovered that when one of the tourniquets moved and broke driver's door food disappears. I looked more closely: there is a harness under the left pillar trim in the driver’s feet:




More specifically, the problem rests on this connector:




First theoretically, then practically I figured out this place. And when he took it apart, he nodded with satisfaction: “This is it...”:




Some contacts looked more or less normal:







... and some simply rotted:




Here is the “mysterious” malfunction. In principle, “everything is very simple” - if you have many years of experience and a day to spare. Or “two days + infinity” - depending on the complexity of the task.


Cleaning, cleaning the connector and remaining contacts from the “green” is thankless and unnecessary work. There is no need to leave something like this. Therefore, I made new connections with a different connector.


The question remains: “How could this happen? How can this be avoided? This means this: the car was not “drowned” and “green” on the contacts and connectors could not have appeared as a result of this. Where then?


As an option, I can suggest this: “Violation of factory technology.” What exactly? Inaccurate dimensions of parts, for example. If the “father” enters the “mother” and has at least some gap, then in this place, provided that a large current flows there, a so-called “vulnerability zone” is created, which provokes carbon deposits on the contact pads and, as a result, poor conductivity – which increases the current, creates excess heat; then there is local heating, melting and here it is - a “mysterious” malfunction. And moisture gets onto the contacts through the slots of the connector seals. All this together creates such dangerous cocktail, which will definitely come out along with an “incomprehensible and strange” malfunction. And it’s good if everything, as in this case, works out “ little blood" But it could have happened differently: due to poor contact, the current strength would exceed the maximum permissible value, which could provoke such strong local heating that it would lead to melting and fire. Will you agree with me?
