Designations of elements and malfunctions of the mounting block
If you can still somehow figure out the electrical circuit diagram, then the mounting block is a dark forest. All we know is the assignment of fuses, which can be found in any table. Some of the relays did not fit into the main mounting block for some reason and the engineers made a strategic decision to space some of the elements across the front panel. Thus, the main mounting block is located to the left of the driver, similar to the old fuse blocks. There is another small unit in the same niche, and another one is hidden in the center console. To figure out what was hidden where, let’s look at the relays that are in these three blocks.
The main block contains 6 relays, each of which has its own functions: these are the low-power lamp relay K1, the wiper drive relay K2, the hazard warning relays K3, K4 and K5 turn on the high and low beam, and the K7 relay starts the heated rear window. Behind the main block there is a second mounting block, which must be contacted in cases where there are problems with the power supply of the fan, fuel pump, ignition unit (these are three relays), and there you can also find the fuses of the ignition controller, speedometer sensor, oxygen mass flow sensor fuse , fuses for the heating sensor, purge valve, fuel pump and power system module. These fuses should be rated at 15 A. Everything that did not fit into these two blocks was hidden in the console - the fog lights and additional lighting relays, the immobilizer, the central locking.

Prevention measures
To prevent problems in the operation of electrical equipment, it is necessary to follow certain preventive measures, in particular:
- Charge the battery at least once a year using a charger. This is especially important to do before winter, as well as in cases where you plan to leave the car in a garage or parking lot for a long time. If the car will be parked, it is better to remove the battery altogether and charge it before installation. The battery also needs to be serviced, checking at least twice a year for the presence of electrolyte in the system and the charge of the device with the engine running and off.
- Never use low quality fuses. The same applies to the use of homemade fuses in the form of a wire or coin. Drivers usually install homemade devices if a certain fuse has failed and there is nothing to replace it with. If you are faced with the need for replacement, then, of course, a homemade version can also be used, but only in order to get to the nearest store and replace it with a normal fuse. Using homemade products can lead to short circuits and even fire.
- Always install only high-quality devices and equipment on your car - from the generator unit to the light bulbs in the dashboard. If the equipment is of low quality, its service life will not be as long, especially since its use over time can lead to inconvenience for the driver.
- If there are problems with the operation of the equipment, they must be resolved immediately. For example, you saw that the Check Engine indicator appeared on the control panel - we recommend that you check the engine as soon as possible. To obtain more accurate results, use computer diagnostics - it will help determine which node needs attention first. It should be noted that the appearance of this light is quite often due to problems in the operation of certain sensors. And their performance, in turn, can be impaired as a result of broken wiring or oxidation of contacts on the connectors. In this case, it is not necessary to immediately change the sensor - you need to change the wire and clean the contact - it is quite possible that this will solve the problem.
- If there are short circuits in the electrical circuit, they must be eliminated, since they can lead to breakdown of the electrical equipment as a whole.
- Never forget that all network elements must be reliably sealed, especially take this into account when installing equipment and wiring yourself. Auto electrical appliances and their circuits should not be affected by moisture or other factors.
