A step-by-step procedure for removing the ignition lock on VAZ cars, as well as replacing the ignition lock backlight lamp.
The ignition lock on cars is changed, as a rule, in 2 cases: due to the failure of the secret (the lock turns with difficulty, wedges) or because of the burning of the contact group. If the lock wedges, then you can use VD-40 or brake fluid, but the result will be temporary.
If contacts 15, 30, 50 of the ignition switch are faulty, then the contact group is changed, if the microswitch contact is faulty, the microswitch assembly is changed. To make a replacement, we need: a thin awl (small screwdriver) and a Phillips screwdriver.
Manufacturer's choice. There are many companies on the market that produce this part. There are a lot of fakes. Do not want to be mistaken - buy an ignition lock from DAAZ (Russia). Reliable, no complaints, it is much easier to find it, unlike, for example, "Autoarmatura". As for the contact group, everything is more complicated here, due to the large number of fakes. We go to the market and ask for a contact group made in the Russian Federation, we check it with a magnet, a good group does not magnetize.
If the malfunction is minor, you can replace the contact group. Quite a lot of owners decide to make a replacement assembly, justifying themselves by the fact that there is a great risk of acquiring a low-quality spare part. part. This is partly true, buying a high-quality ignition lock, especially for this model, is not an easy task, but quite solvable. The main thing is not to save money, especially when you consider that the price of the most expensive models rarely exceeds 1.5 thousand rubles.
Let's say you bought quality parts. How to make a replacement? - Read on for a step-by-step guide.
Removing the ignition lock and checking the contact group
1–8 - conditional numbering of the contacts of the wiring harness block. Please note that the shoe socket is asymmetrical (reference point is the locating protrusion).
1. The first thing to do is to disconnect the terminal with the "-" sign from the battery.
2. Remove the steering wheel and lower casing from the steering column. To do this, you need to unscrew the 5 mounting screws from the casing.
3. Next, we find the screws securing the ignition lock, unscrew them, in some car models, there are no screws at the bottom. Disconnect the lock harness connector from the on-board network and carefully pull the harness out from under the dashboard into a comfortable position.
4. To remove and replace the ignition switch on a VAZ 2110 car, unscrew with a screwdriver or drill four bolts with self-tapping heads. Remove the switch.
5. The installation of the new switch is carried out in the reverse order: only initially press the tongue of the anti-theft device. To do this, insert the key into the switch and turn it from position "0".
6. Install the key or awl in the lock, you need to do this alternately in three positions, in each check the resistance between the contacts. If the contacts are completely serviceable, then the resistance will be zero, and if they are faulty, then infinity, if something is burnt, then the ohmmeter will show resistance.
7. To check the correctness of the backlight, you need to apply a direct current of 12 V to pins 2 and 6 of the wiring harness block. In the event that the backlight lamp does not light, it means it is faulty, there is an open circuit in the circuit, we change it according to the diagram below.
Procedure on a Daewoo Matiz car:
Replacing the ignition switch illumination lamp
- Disconnect the connector from the backlight socket.
- Next, use pliers to remove the cartridge with the lamp by grabbing its terminal.
- Install a new LED. A12-1.2 lamp with an original cartridge is used to illuminate the ignition switch.
