A malfunctioning ignition switch is a rare but annoying problem that requires replacement of the assembly or part of it. Replacing the ignition switch of a LADA Granta is quite feasible in a “garage” environment and does not require high plumbing skills or specialized equipment.

Malfunctions of the ignition switch LADA “Granta”

Ignition switch malfunctions can be divided into two types: electrical and mechanical. Electrical faults include the contact group of the lock, as a result of which individual energy consumers (most often the starter) stop working or the entire electrical system as a whole fails. This may also include a faulty vehicle immobilizer. Mechanical failures occur due to the breakdown of parts of the ignition switch or contact group, as well as physical wear of the contacts. This also applies to cases where, due to poor contact, the plastic parts of the contact assembly heat up and melt. Signs of a malfunction in the ignition switch of the LADA Grant:

the key does not turn;
turning the key does not turn on the ignition;
the starter or other electrical devices do not work.

The last two signs do not necessarily indicate problems with the ignition switch, but they certainly appear when the contact group is not working properly.

To eliminate the malfunction, it is necessary to replace the LADA Granta ignition switch or part of it, for example, a group of contacts.

What is needed to replace the Granta ignition switch

To replace the ignition switch you will need:

key to 10;
a thin chisel and a hammer drill (or a drill with a drill for drilling screws with self-tapping screws);
screwdriver;
new LADA “Granta” ignition switch or contact group.

How to replace the ignition switch of a LADA Granta

The work can be carried out both indoors and outdoors. To avoid a short circuit, before removing the ignition key, it is necessary to disconnect the ground terminal from the Granta battery. The ignition switch of the LADA "Grant" is removed as follows:

unscrew the five lower screws securing the steering column cover;
unscrew the mounting bolts of the left and right casing;
remove the lower part of the Granta steering column casing;
remove the upper part of the casing;
tighten the wire connector clamp attached to the ignition switch;
disconnect the connector from the contacts of the Grant ignition switch;
press the latch of the immobilizer antenna unit wire connector;
disconnect the connector of the antenna unit of the LADA “Grant” immobilizer;
using a thin chisel and hammer, unscrew and remove the screws securing the ignition switch to the steering column, or drill the bolts with a drill;
remove the LADA Granta ignition switch from the steering column.

Tip: There is no need to change the lock group. It is cheaper to find the cause of the malfunction and simply replace a part, for example a group of contacts.

Standard terminal designations

The colorful mix of wires in a car is actually very well organized, since many parts of the car's electrical equipment are standardized. The numbers on various components and connecting elements of wires, as well as in electrical circuits on all German and some foreign cars have the same meaning:

Terminal 15 receives power only when the ignition is turned on from the ignition switch, while, along with the ignition/injection system, those consumers of electricity that should receive current only during operation of the vehicle are supplied with current. The wires to terminals 15 in most cases have a black sheath, sometimes with an additional colored stripe for certain current consumers.

Terminal 30 receives direct current from the battery positive or from the generator when the engine is running. If the tools are handled carelessly, this can lead to short circuits or cause sparks to rain if the wire connected to the battery negative is not removed. These wires, which are always live, are in most cases red, sometimes with additional colored stripes.

Terminal 49 refers to the intermittent and emergency light system.

Through terminal 53, voltage is supplied to the glass cleaning system.

From terminal 56, current is supplied to the low beam headlights through the yellow and yellow-black wires, as well as to the high beam headlights through the white and white-black wires.

Terminal 58 supplies power to the front parking lights, as well as the rear lights and license plate lights. The main color of the wire sheath is gray, sometimes with an additional colored stripe.

terminal 75 receives current when the ignition key is in the "On" position.

Terminal 31 is the ground terminal, through which the electrical consumer must be connected to ground in order to complete the electrical circuit. The corresponding wires have a brown sheath.

Labeled electrical connectors

In the Audi A4, individual wires are often bundled together in a black sheath, making it difficult to find a specific wire. In this case, orientation assistance is provided by multi-pin connections, which this chapter describes the exact number of wires and their exact location in electrical diagrams.

Terminal designation

Let's look at the main wires, or rather groups of wires, they are often called buses in electrical circuits, and they have standard symbols:

– Terminal “31” is the wires that are connected to the car body (ground)

– Terminal “50” is the wire, roughly speaking, that goes to the starter.

– Terminal “30” are wires on which +12 volts are always present, regardless of the position of the ignition switch, i.e. they are directly connected to the + (plus) terminal of the battery.

– Terminal “58a” supplies current to the front parking lights, rear lights and license plate lights.

– Terminal “75X” – on this bus +12 volts is present only in the “Ignition” position, but is absent at start, i.e. this is the case when +12 volts disappears from this bus in the “Starter” position

– Terminal “15a” is the wires on which +12 volts are present, in the “Ignition” position and the “Engine Start” position. The voltage from bus “15” powers the important parts of the engine, without which it will not start: spark plugs, ignition coil, various valves and the “brains” of the engine.

All of the above wires (except for ground “31”) go to the ignition switch.

How to disassemble the ignition switch of a LADA Granta

To disassemble the ignition switch, follow these steps:

bend the wire harness clamp on the Grant ignition switch connector housing;
remove the terminals with wires from the housing;
tighten the latches securing the plastic cover and remove it from the lock;
press out a pair of plastic contact group clips;
remove the contact block from the lock body.

After disassembling the lock, you need to check the condition of the contact group and terminals on the wires and clean them with fine sandpaper or replace them with new ones.

Assembling the ignition switch and installing it on the LADA “Grant” is carried out in the reverse order of disassembly and removal from the car.

P O P U L A R N O E:

Not all cars have a mains voltage monitoring system. Previously, domestic cars had a regular light in the dashboard indicating that the battery was charging. This is clearly not enough information. It would not be a bad idea to install an additional digital voltmeter or at least an indicator of several multi-colored LEDs showing the main thresholds of permissible voltages. Below are three simple car voltage LED circuits.

In some cases, you can independently diagnose a washing machine malfunction by reading the indicators on the front panel of the washing machine. The washing machine's fault code is displayed on the digital or LCD display. Next, we will take a closer look at the diagnostic codes of Indesit and Ariston washing machines.

Another charging scheme is very similar to the previous one, but differs in that it turns off after charging is complete. The charger is started by pressing the “start” button on the front panel; when supply voltage is applied to the circuit, relay K1 is activated and provides “self-capture”. Know more...

About the conventions

Let us remember that the practical Lada Granta model went into production back in 2011. This modern car is full of new modifications of complex instruments and electronic devices. All this aims to provide the driver with maximum driving comfort. Today VAZ produces the Lada Granta in three versions in terms of equipment:

The first two options have the same wiring diagram, but in the “Lux” it is different. It's a shame that the factory operating instructions for the car do not contain this wiring diagram. However, do not rush to get upset, because such an album with the entire list of schemes can be purchased in the market network of auto goods.

Electrical cabling involves the presence of a large number of bundles. The wiring diagram has symbols and serial numbers, each of which is assigned to a strictly specific pantograph. These consumers in the diagram are switched into the general network via conventional lines. To increase clarity, the developers used different colors for the lines. Next, the wires are assembled into bundles, which are connected to electrical units using special connectors.

The first number in the wire marking indicates the plug, connector or terminal to which this cable is connected. The number present behind the fraction sign indicates its correspondence to the contact number of the pantograph.

The reader can familiarize himself with the operating principle of a particular electronic unit on his own. If the defects are minor, then they do not create difficulties during the repair or replacement process. But the situation changes when a complex component fails, which implies the need to turn to electricians. To understand the situation with a malfunction of a specific pantograph, the owner of a LADA Granta does not need to remember all the details and details of the layout drawing, but it will be enough to know the location of the device and the features of the wiring leading to it.
