Wiring diagram of Lada Priora: full pinouts and decoding


Car designs are rich in electrical equipment and electronics. Electrical wiring for a car is as important as veins are for the human body. Experienced drivers can navigate this web of wires without any problems, but for inexperienced drivers, learning to read electrical diagrams is useful, because if a problem occurs, you can figure out where it happened and what to check before calling a car service center.

There are three main lines in the wiring of the Lada Priora electrical circuit: for supplying energy, the starting circuit and the circuit for supplying energy consumers. Each of the car's systems is connected by a bundle of wires that connect instruments and electrical equipment. There are four main harnesses in the Priora electrical circuit:

  • coming from the instrument panel;
  • providing motor control;
  • front electrical harness;
  • rear electrical harness.

All these harnesses are connected to each other using detachable connections. The connectors are located under the dashboard. Each of the harnesses is assigned a serial number.

In addition to the main ones, there are secondary electrical harnesses:

  • installed in the front passenger door;
  • identical in both the left and right rear doors;
  • installed in the driver's door;
  • connecting the backlight of the license plate;
  • connecting the electrical package.

Each element in the diagram corresponds to a number with an explanation. Since all elements are standardized, their designations are identical on car diagrams of all car manufacturers. Next to each electrical appliance, the connectors that go to them are indicated. The pins or sockets of the pads are also numbered. Each block has colored wires (the color of the wires in the diagram corresponds to the color of the wire in the car).

At the top, the wires are numbered with numbers written through a fraction. The first number indicates which electrical appliance it goes to. The second number indicates which connector the wire goes to. Wires in electrical wiring connected using connectors (marked with the letter C and a number), or using terminal blocks (marked with the letter S and a number).

The layout of pins, or connecting contacts to certain nodes is called pinout.

Reasons for the breakdown of the ICC

As it would seem, the failure of the light control module on a Priora depends on the number of times the headlights are turned on and off, but this is not the case. Most breakdowns occur not due to the physical impact of a person on a given electrical appliance, but precisely due to the load from constantly switched on headlights. How is this explained?! Driving for a long time with the headlights on provokes heating of the tracks in the MUS board, thereby, when the electrical wiring heats up, its resistance increases and these tracks break.


Priora with daytime running lights

This problem occurs quite often and most prior managers run to the store and buy a new module at a very expensive price. Never rush into buying an ICC as it can be repaired without spending a penny.

If the light control module fails on the road, then you can read how to turn on the lights when the MUS is not working on a Priora here.

Front Passenger Door Wiring Harness

The electrical wiring of the left and right front doors of the car differs in the additional control buttons for mirrors and power windows on the driver's door.

Tuning and replacement of the center console on Lada Priora and Kalina

Modern versions of cars are supplied to the market with a restyled version of the tidy. Here, a relatively old generation, navigation and a liquid crystal display appeared. Installing an updated shield requires the following steps.

Selecting the required version

There are only two types of updated designs with and without a CAN bus. The nuance is that the versions are completely identical in appearance. In order to find out which variety is suitable, you need to check the production date of the car. Machines manufactured before 06, 2012 are not equipped with this technology. The article numbers for the new devices with navigation are as follows:

  • 2170-3801010-50 without CAN;
  • 2170-3801010-60 with CAN.

Also in the kit you need to purchase a navigation antenna and a steering column switch of the appropriate design.

Installation nuances

For Lada Kalina versions, all devices are not equipped with a CAN module. Also the old generation of Priora. Here the installation is carried out without modifications or nuances - just snap out the old panel, remove the terminals, and mount the new set on the stock fasteners. Next, you need to install a navigation antenna on the roof and connect it to the appropriate connector. The second case is when an old panel with a CAN unit, but without navigation, is replaced with an analogue one. Here it is necessary to rearrange the contact connectors of the standard wiring from positions 10-11 to sockets No. 28-29. In case of incorrect operation of the devices, the replaced wires are swapped with each other. After the repair is completed, the counters should reset to zero.

Pinout of the Lada Priora instrument panel connector

The information panel installed on the dashboard contains the most data.

Each auxiliary device is connected to the control lamps on the panel. A computer chip monitors the operation of all devices. Its mission is to control the operation of the panel in accordance with its firmware. All elements of this device are mounted on an electronic board, on which connecting tracks are applied: a microcircuit with an ECU, an LCD monitor, resistances, transistors, a connector socket for the wiring harness. There are 32 cells in the connector for connecting the instrument panel.

Topic: Is it possible to connect the light control module from Priora to a VAZ 2110?

Ideally, I would like to get a working connection diagram for this module instead of the standard “decimal” ones that are on the instrument mask.

Re: Is it possible to connect a light control module from Priora to a VAZ 2110?

Connecting a light control module from Priora

We have a module with one 12-pin connector (No., color in prior) wire purpose (function) 1 - orange-black - input indicating that the rear foglights are on 2 - orange-white - output controlling the activation of the rear + front foglights 3 - yellow - input indicating that the front ones are on prottumanok 4 - brown - output control the brightness of the backlight of the buttons 31 - black - ground (it is also mass in Africa) 30 - pink - input +12volts from the battery 56 - green - output +12volts turn on the head light 58 - whitechern - output +12volts turn on dimensions 56v - serkras - +12 volt input after turning on the head light to control the fog light 58v - white - input for the illumination of the Xz - synchern - +12 volts after the ignition switch G - blue - to control the headlight range control

56 Xz 31 58b 56b G 30 58 4 3 2 1

After comparison with the 2110-2112 scheme, the following came out:

1) it is possible to connect this unit without an electrical package control unit Priors without foglight controls (I will finalize it later) all other wires somehow match in color (.) must be connected to the connector (standard 2110) light control except for the following wires: 1 – orange-black, 2 – orange white, 3 – yellow, 4 – brown (use standard regulator 2110), G – blue (if you want to connect the headlight range control, knock on the priors)

2) it is possible to install a control unit for the Priora electrical package (but later)

Re: Is it possible to connect a light control module from Priora to a VAZ 2110?

That is, here are the contacts of the ICC Priora that should be used? 31- black - ground (it is also mass in Africa) 30- pink - input +12 volts from the battery 56- green - output +12 volts turns on the head light 58- belchern - output +12 volts turns on the headlights 56v-serkras - input +12 volts after turning on the headlight light for control fog 58V - white - input to the Xz block illumination - synchern - +12 volts after the ignition switch

Here is the standard switch for the low beam and dimensions of the old-style instrument panel (on diagram No. 36)

30 (pink) - connect to 56 (green) 58 (white-black) - connect to 31 (black) 56 (green) - connect to 58 (belchern) X (blue-red) - this is also a mass.

I found the remaining contacts in the VAZ 2110 mounting block: Ш3-4 (+12V) - connect to 30 (pink) Ш3-1 or Ш3-3 - connect to 56V (serkras) Ш2-8 - connect to 58V (white) Ш1-4 and Ш4-17 - connect to Xz (synchern) Is that right?

I looked at the contacts from the mounting block here

Re: Is it possible to connect a light control module from Priora to a VAZ 2110?

No, it’s not right on the standard light switch 2110 to connect all the wires in the same colors with the Priora IUS, something like this

Priora 2110-212 30 (pink) - connect to 30 (pink) 58 (white-black) - connect to 58 (belcher) 56 (green) - connect to 56 (green) X (blue-red) - X (blue-black) +12 volts after the ignition switch

The wires of the MUS Priors 1 - orange-black, 2 - orange-white, 3 - yellow, have a trigger switch (i.e. pressed once, turn on a second time, turn off) the triggers are located in the Priora's electrical package unit, so simply connecting them to 2110 will not work, you need to come up with a diagram

Pinout of the lighting control unit on Priora

This switching and control combined module has several functions and is used to turn on/off parking lights, headlights, select the desired light switching mode, turn on/off fog lights, adjust the brightness of the backlight combination, control the headlight range control, on/off and control light inside the cabin and instrument lighting. The module is connected to the vehicle’s on-board network via chip No. 1118-3724500.
