Location of the Lada Granta ECU

We can talk for a long time about how important the correct operation of the electronic control unit (ECU) is. The functioning of the heart of your car depends on it: from increased fuel consumption to the fact that the car may stall as a result of incorrect operation of the controller.

I would like to immediately convey a special greeting to the designer of AvtoVAZ, who came up with this arrangement of this block. In my opinion, I can't think of a worse place. See for yourself.

The ECU is located under the glove compartment under the passenger's feet and hidden under the upholstery. The upholstery is attached to the body on the right with a self-tapping screw.

If your interior heater (radiator) leaks, the antifreeze will go straight to the control unit, causing almost 100% failure. Even though the Lada Granta is initially equipped with a good quality imported Visteon radiator.
As you correctly noted, water can get in from under the hood. The rubber plugs on the Lada Granta are not of very good quality, so when they dry out, water will flow onto the controller. To prevent this from happening, check the condition of the rubber plug.
If the drainage hole (which is shown in the video below) becomes clogged, water may flow into the cabin.

In general, as you understand, the location of the ECU on the Grant is not the best! So we just need to face it.

Why ELM 327 does not connect to the VAZ 2110 ECU

So, why doesn't ELM327 see the ECU? What should I do so that the device can connect and see the block? Today you can find many different adapters for testing a vehicle on sale. If you buy an ELM327 Bluetooth, most likely you are trying to connect a low-quality device. Or rather, you could have purchased an adapter with an outdated version of the software.

ELM327 Bluetooth devices with outdated firmware use a different Bluetooth module that allows you to interact with two of the available six protocols. Accordingly, you can synchronize the device with a smartphone, but when you try to connect the device to the control unit, it will inform you that there is no connection with the ECU.

So, for what reasons does the device refuse to connect to the block:

The adapter itself is of poor quality.
Problems can be with both the device’s firmware and its hardware. If the main microcircuit is inoperative, it will be impossible to diagnose the engine operation, as well as connect to the computer.
Bad connection cable. The cable may be broken or inoperative itself. The wrong version of the software is installed on the device, as a result of which it will not be possible to achieve synchronization (the author of the video about testing the device is Rus Radarov)

If you own a device with the correct firmware version 1.5, where all six of the six protocols are present, but the adapter does not connect to the ECU, there is a way out. You can connect to the unit using initialization strings, which allow the device to adapt to the commands of the machine’s motor control unit. In particular, we are talking about initialization lines for diagnostic utilities HobDrive and Torque for vehicles that use non-standard connection protocols.

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.

Appearance and body structure

As for the dimensions, the VAZ-2112 (16 valves) decreased in length by 93 mm. This change occurred in the rear overhang area. But despite all this, the size of the wheelbase did not transform. The body length was 4170 mm. And the height of 1676 mm and width of 1430 mm remained classic for the “tenth” family. The top line on this body very smoothly transforms into a rather small rear overhang and a huge wing. This design allowed the developers to make the car more manageable.

The one hundred percent zinc-coated body of the “10”, which at one time became very popular, is still susceptible to corrosion. Many owners of new cars did not consider it necessary to perform anti-corrosion treatment. The bottom was rapidly rusting to holes.

Pinout of the lighting control unit on Priora

The module is connected to the vehicle’s on-board network via chip No. 1118-3724500. The standard terminal pinout on a VAZ 2170 looks like this:

G56b – for the gearbox for adjusting head lighting devices;
58b – output from lighting and instruments;
31 – neutral earth cable;
Xz – 12 volts from pin 15 of the ignition switch;
56 – relay switch for high and low headlight modes;
1, 3 – connection of fog lights;
2, 4 – sending a signal to the controller;
58 – dimensions;
30 – power supply from the ignition switch design.

The standard electrical connection diagram (pinout) for the VAZ 2170 Priora has its shortcomings and strengths. However, thanks to the simple design, you can eliminate defects yourself, without the involvement of service station specialists.
