Gazelle is a very popular truck in Russia. On the basis of the GAZ-3302, a lot of cars for other purposes are also produced. These are both public transport and passenger minibuses. What unites all these models? They are united not only by a common frame structure, but also by a single instrument panel. Gazelles of different years of production were equipped with different dashboards. Well, let's look at what exactly and what are the features of each shield.

Destination

The function of any "device" is informational. This also applies to the Gazelle Business instrument panel. On a small area in the dashboard there are all the necessary indicators, lights and scales. Usually the shield is located behind the wheel, in front of the driver's eyes. But there are exceptions. For example, in the UAZ "Hunter" the panel is located in the center. But we will not consider the tidying of this car yet. Let's get back to our Gazelles. Outwardly, their panels are three to five round dials with several signaling sensors. In any shield, the main dials are:

• Speedometer.
• Tachometer.

They are the largest and centered. In addition, there are a lot of auxiliary elements on the instrument panel ("Gazelle" of the old model and the new one). These dials inform the driver about:

• The current temperature of the engine (namely, the coolant in the engine jacket).
• Oil pressure in the system.
• Fuel level in the tank.
• Voltage in the on-board network.

If we consider more modern tidy, information about the current time will also be displayed here.

Where is it installed?

Note that the Gazelle instrument panel can also be found on other cars. These are Sobol and Volga. The device has the same wiring diagram. Externally, these guards look identical.

Types

There are several types of panel data:

• Old-style Euro-1. Installed on cars from 1994 to 2002 inclusive.
• Old-style Euro-2. These shields can be found on Gazels with a new "muzzle" (with drop-shaped headlights).
• New sample. They are installed to this day on Nexts, starting with Gazelle Business.

Below we will look at the features of each Gazelle instrument panel.

Euro 1 panel

This tidy was installed both on the "Sable" and on the "Gazelle" of all modifications. What design she has, the reader can see in the photo below.

Remotely, this shield resembles the panel "Lada"-seven. But still, this is an original design. There are no electronic signs here. Available only:

• Speedometer.
• Tachometer.
• Oil pressure (not level) sensor.
• Network voltage indicator.
• Fuel level and antifreeze temperature sensor.

The shield was produced in this form for about eight years. No changes were made during this period.

Euro 2 panel

This tidy is also called "Riga". It was also installed on the Volga, in particular the 31105 series. This shield has a slightly different design and appearance. It was developed specifically for the new torpedo, with a rounded visor. There are no new sensors here, but the location of some dials has changed.

The speedometer scale has now become larger in diameter, and the antifreeze temperature and oil pressure sensors are combined into one "well". The changes also affected the odometer. If earlier the main odometer was designed for a run of up to one hundred thousand (after which it was reset to zero), now its boundary line is one million kilometers. Of course, few people have seen a Gazelle with a similar mileage, but still the addition of one digit greatly facilitated some work and maintenance (no need to guess and think when to replace the chain, and even overhaul the engine). According to the reviews of the owners, the new Riga Gazelle instrument panel is much more convenient to use. Also, the arrow of the tachometer and speedometer does not “walk” here. Starting in 2003, these scales are electrically powered, not wired. Readings are more accurate.

Euro 3

For the first time, such a tidy appeared on Gazelle Business cars. Shieldold-style Gazelle devices went out of fashion, and all the “gazelles” began to install an updated panel in their car. The owners of the Volg were also engaged in the same alterations. Indeed, the new shield has become much more informative, convenient and practical. What can I say, the design is much more modern. According to reviews, with him the interior looks fresher and not so dull. How the updated tidy looks like in practice, the reader can see in the photo below.

But it is worth noting that this shield has slight differences in design. So, on some models, the instrument scales had a darker shade. But this did not affect the information content in any way - the reviews say. Another feature of the new shield is the presence of a sound indication. Now the driver can hear a characteristic signal if:

• The fuel level has dropped to the minimum mark.
• The engine temperature has increased to 105 degrees Celsius or more.
• The handbrake was not released. Remarkably, the signal is triggered only when the car starts moving at a speed of 2 or more kilometers per hour.

The new tidy got large modern dials. Now the scales of the speedometer and tachometer are in opposite places (compared to the "Riga"), and their diameter has become the same. On the left is the fuel gauge, and on the right is the coolant temperature sensor. But where did the mains voltage and oil pressure indication go? The answer is simple - this data is in the on-board computer. It is locatedin the "well" of the tachometer. By default, only the time is shown here. But if you press the button on the right, you can switch the mode. So, the driver can check the data from the voltmeter and oil pressure in real time.

Remarkably, when the oil drops below 0.2 bar, the blinking window with the sensor will light up.

There is a digital odometer on the left side. Above shows the total, and below - the daily mileage. It is reset by pressing the button on the left. Also on the panel of the new sample there are 20 indicators (including ABS and EBD), which light up in case of a malfunction of a particular system.

Working principle

The action algorithm is the same for all panels. Each light bulb and arrow interact with a specific element. So, the readings of both speed and mileage come from a sensor that is screwed onto the box. Engine information comes from the crankshaft sensor. And the voltage data comes from the generator terminals. What is noteworthy: if you do not connect the voltage contact, the car will not charge even with a working generator. This problem is accompanied by a red battery light on the panel. If it is on, it means that a break has occurred and the wire does not fit the contact of the tidy connector. As for oil pressure and coolant temperature, this information comes from the terminals of the corresponding sensors.

Problems

Are there any problems with the above shields? Unfortunately, the owners are faced with the problem of tidy malfunction. This happens least often at the very first panel, the old model. It works like clockwork. The Riga panel may inaccurately give information about the level of oil pressure. Also, the speedometer often jams here. Along with this, the odometer refuses to work. But most of the complaints, surprisingly, are caused by the new instrument panel of Gazelle Next and Business.

So, the most common malfunction is resetting the mileage (moreover, total) at a run of 60 thousand kilometers. Because of this, it is impossible to accurately control the passage of maintenance and a number of other repair operations. But that's not all. The daily mileage is also reset - reviews say. This happens if the voltage in the network is less than 11.5 volts. Also, the data is erased if the terminals are removed from the battery.

What else?

The Gazelle instrument panel of the new model does not work even when installed in the old Gazelle. You need to mount it correctly - just throwing pads with contacts will not work. For a successful installation, you need a pinout of the Gazelle Business instrument panel.

Among other malfunctions, it is worth noting the freezing of the speedometer and tachometer needles in one position. Most owners start to panic and completely disassemble the shield. But you don't have to. The problem lies in the insufficient contact of the connectors.

Installation

To install the panel, you must remove the old shield. To do this, you need to dismantle the steering wheel using a special puller and unscrew a couple of screws from the decorative lining of the shield. You should also unscrew the bolts securing the tidy itself.

To do this, you need a head "8". After that, you can remove the old panel and put a new one in its place. But as we said earlier, just throwing the connectors will not work. Need a pinout for the Gazelle Business instrument panel. There are four pads in total - XP1, 2, 3 and 4. Consider how to connect each:

• XP1. The first, fifth, sixth, seventh contacts are closed to ground. As for the rest, they are connected to the sensor signals. The first contact is the air damper cover relay, the third is DTOZH, the ninth and eleventh are the oil pressure sensor and the fuel level in the tank, respectively. The rest of the contacts are "Reserve". We do not touch them and do not connect anything to them.
• XP2. Contacts number two, four, nine close to ground. On the "plus" there are terminals, everything from the fifth to the thirteenth.
• HRZ. Terminals number two and thirteen are connected to the positive contact + 12V. The first, eighth and twelfth terminals are closed to ground. The sixth connector is the speedometer speed sensor, the ninth is the ignition coil, the eleventh goes to the engine control unit.
• XP4. Here, almost all contacts must be connected to the "mass". This applies to connectors from the first to the seventh inclusive. Only the sensor for the presence of water in the fuel filter (if any) and the glow plug switch go to the "plus". These are slots number eight and nine, respectively.

By the way, if the car does not have an ABS and EBD system, the outputs to these sensors must be plugged. How? It is enough to connect them to the "mass".

So, we found out what the Gazelle dashboard is, what types it is and how it is connected.
