How to determine the malfunction?
Diagnostics of voltage in electrical wiring is carried out as follows:
- First, you will need a test lamp with wires connected to it. One of them is connected to the negative of the battery or the mass of the vehicle, that is, the body. And the second probe should be connected to the section of the electrical circuit being diagnosed. In this case, it is desirable that the connection point be as close as possible to the battery or safety device.
- If after connection the light starts to light up, this indicates that there is voltage in the circuit. In particular, we are talking about the area between the connection and the battery.
- The remaining components of the electrical circuit are diagnosed in a similar manner. When it happens that the light bulb does not light up and there is no voltage, this indicates that the faulty source is located between this point and the last one where the voltage was. As practice shows, wiring problems are often associated with poor connections, so when problems are detected, the first thing you need to do is check the contacts. Also remember that in some sections of the wiring there is voltage in the circuit only when the ignition key is turned.
An equally important point is to find a short circuit; this problem is relevant for many vehicles, including Grant. One way to find the short circuit point is to dismantle the safety element and then connect a test lamp or tester to its socket. All other components in this circuit must be turned off, that is, there should be no voltage in it. Try moving the wires in different directions, while watching the control - if it starts to burn, then somewhere in the area one of the contacts is closing. Most likely, the reason lies in the rubbing of the insulation (the author of the video is the Kroom&coTV channel).
As for diagnosing grounding reliability, it is carried out as follows:
- First you need to disconnect the battery terminals, then connect one of the probes of the diagnostic tester (multimeter) or a warning lamp to the body of the Lada Granta.
- The second probe should then be connected to the connection or ground point you want to test.
- If, as a result of the connection, the lamp lights up, this indicates that everything is normal with the grounding, you can begin diagnosing other circuits.
And one more point that should be discussed in more detail is diagnosing the integrity of the wiring. This procedure is carried out in order to determine whether there is a break in the wiring or not.
Integrity check is done like this:
- First you need to turn off the voltage from the wiring and diagnose the integrity using a test light and a connected power source.
- Next, you need to connect the wiring from the light source to the ends of the electrical circuit being diagnosed, or one probe to the positive, and the second to the car body. If the control lights up after connection, this will indicate that there are no breaks in the circuit. If the lamp does not light up, then most likely there is a break in the circuit.
- In a similar way, you can check the functionality of the switch by connecting a test lamp to its terminals.
- After the switch is activated, the control should light up.
Instrument clusters and tuning
Tuning the Kalina torpedo
The listed devices and controls are located on the so-called dashboard of the car. You can install an original torpedo on Kalina, thereby diversifying the interior of the car.
The instrument cluster is closed with a special cover, which is an overlay on the panel. If necessary, the cover can be easily removed and replaced.
Auto-tuning instructions can be found on special websites and forums. Tuning the combination of all devices is not difficult if you have minimal skills in working with a soldering iron. The instrument cluster on Kalina is identical to the combinations on the VAZ 2118 and 2119. Nowadays, the GF 618 instrument cluster on Kalina, based on LEDs, is very popular; it has a built-in route diagnostic computer.
Using the instrument panel, the driver can monitor the vehicle’s condition, driving characteristics and other functions and processes that affect the safety of movement. Also, with the help of indicators, the car owner will be able to operate it correctly. Next, a description of the indicators on the instrument panel will be given to make it easier for a novice driver to understand.
List of elements on the Lada Granta dashboard wiring harness diagram
As with all cars, this is the most complex block in the overall electrical connection diagram, due to the large number of connectors.
1/2 — blocks of the tidy harness to the front wire bundle; 3/4 — bundles of instrument panel wires to the rear harness; 5 — lighting control unit; 6 — ignition switch; 7 — computer mode toggle switch; 8 — windshield wiper mode switch; 9 — instrument board; 10 — light signaling switch; 11 — luggage compartment lock switch; 12 — diagnostic block; 13 block of the instrument wiring harness to the block of the air supply wire bundle; 14 — rear window heater breaker; 15 — alarm switch; 15 — brake light switch; 17 — connection of radio equipment speakers; 18 — connector for connecting a radio; 19 — steering wheel rotating device; 20 — driver airbag module; 21 - no; 22 — mounting fuse block; 23 — power steering connector; 24 — cigarette lighter socket; 25 — backlight lamp for stove control; 26 — interior lamp; 27 — block of the tidy harness to the block of the ignition wire bundle; 28 — control device; 29 — clutch pedal position signal breaker; 30 — electronic accelerator pedal; 31 — supernumerary resistor; 32 — stove motor; 33 — heater switch; 34 - door lock control module.

The instrument panel as standard on the Lada Granta has 32 contact connectors. Consequently, the owner has the prospect of adding or modifying equipment.
Maintenance frequency
Motorists should also be aware of the maintenance schedule for the Lada Grant, since it is during these periods of time, according to the automaker, that the service life of some consumables begins. Plus, it is necessary to adjust some systems, correct components, check the serviceability of mechanisms, etc.
For Lada Granta cars, the frequency of maintenance is determined by the mileage or age of the vehicle. This allows you to divide the procedure into several main maintenance procedures. Usually the frequency of maintenance is indicated from the zero (first) to the eighth (seventh) maintenance.
The current frequency specified in the AvtoVAZ company regulations in relation to Lada Granta models is as follows:
- 2000-3000 km;
- 14500-15000 km or 1 year of operation;
- 29500-30500 or 2 years;
- 44500-45500 or 3 years;
- 59500-60500 or 4 years;
- 74500-75500 or 5 years;
- 89500-90500 or 6 years;
- 104500-105500 or 7 years.
The frequency of maintenance for 8 procedures for visiting certified service centers is accordingly prescribed here.
Required spare parts
The maintenance regulations indicate which elements must be replaced during the next service.
Based on the technical regulations, the following mandatory parts and consumables are identified that must be replaced at certain intervals:
- The air filter is changed at 30, 60 and 90 thousand kilometers.
- The cabin filter needs to be changed every 15 thousand, that is, within the framework of TO1, TO2, etc.
- Engine oil, like the oil filter, is changed every maintenance, starting with the so-called zero. Although there are some nuances here. Not all versions of the Lada Granta must undergo zero maintenance.
- The brake fluid is changed for the first time after 45 thousand km, and then at 90 thousand kilometers.
- Spark plugs are changed after one maintenance, that is, at a mileage of 30, 60, 90 thousand km.
- According to the regulations, the timing belt will have to be changed for the first time at 75 thousand km.
- Drive belts must be replaced at 30, 60 and 90 thousand.
- The oil in a manual transmission lasts up to 90 thousand km.
- The fuel filter is changed in the same way as the drive belt and spark plugs.
- The lambda probe or oxygen sensor needs to be changed for the first time after a mileage of 75,000 km.
