Additional Lada Vesta body electronics unit and LEDs

November 13, 2017 Lada.Online 93 039 86

In some configurations of the Lada Vesta (for example, Lux), an additional body electronics unit (EMM or comfort unit) is installed inside the panel, which is responsible for the operation of the dimensions, daytime running lights (DRL), and wipers. Under some circumstances, the external output circuits of the EMM may short circuit, causing the light sources to not operate. Let's figure out what can be done in this case.

Where the central body electronics unit (CBKE or BCM) and the additional body electronics unit (EMM) are located is shown in the photo:

The electrical circuits of modern LADA cars are very different from previous AvtoVAZ models. Some of the relays have disappeared and instead they are replaced by an electrical package control unit (comfort unit), which is responsible for the operation of the ESP, central locking, turn relays, turn signals, etc.). Lada Vesta and XRAY use a similar CBKE module (central body electronics unit).

Short circuit protection has tripped

The optional body electronics unit uses drivers (vnq6004sa), which have built-in non-volatile memory and electronic short circuit protection. After the electronic protection is triggered, the lighting control driver stops supplying voltage to the headlights or DRL contacts until it receives an unlock command from the controller.

If the command is not received independently, then it is possible to unlock the EMM manually using a special Grade-X scanner (available from LADA dealers). After connecting the device, you need to find the corresponding functions (left or right side lighting) and check the appropriate boxes. After which we perform a reset to factory settings, and the operation of the dimensions with DRLs is restored.

Purpose and description

Lada Largus CROSSodil › Logbook › Controlling the radio using the steering column joystick

On my previous Renault car, I had a steering column radio control from the factory; the radio itself, by the way, is the same as on the Largus. I got used to the controls and first of all I looked for it for a long time in Largus, but it wasn’t there. Muscle memory so to speak. It seems like the mafon is nearby, but it’s not convenient for me to control, and if the road is not even, it’s very difficult to hit the buttons. And here on the joystick and volume, and answer the call. There is no need to stretch, releasing your hands from the steering wheel to the radio.

In general, I decided to install controls, especially since many on Largus do this. I read blogs, watched videos on Largus Shop, and here’s what I don’t like. It seems like there is a template, but by making it according to it, it’s like a collective farm and everyone has a slot. What's the point of this template then? And no matter how much I search, I can’t find the steering column panel with a slot, even if I could find the part number. Well, isn’t it true that Renault doesn’t install this steering column anywhere and only supplies it to the rear wheel drive? Maybe someone has seen a shield with a slot and could compare it with the template.

Further, an analysis of the Internet showed that they install it in 2 ways: 1. They cut out a window using a template, it doesn’t look very good. The joystick is recessed into the casing:

2. A smaller window is cut out (the general template is used as a basis):

I like option 2 better.

Just now I noticed another topic, yrbond writes: Help, I’ll post here too! I bought a joystick 255522215R in the Largus shop, received it, cut a hole in the casing, connected this device in the connector... but button 17 according to the manual (mute the sound, turn on and off the phone) does not work at all, and the Radio and Media buttons have their functions swapped . Radio tape recorder HUMAX model HARN 1002, what should I do, it doesn’t work, maybe it’s a firmware issue?

Apparently I have the same phone. What to do. Did I really buy it in vain?

UPD from 10/2/2015 I handed over the joystick to the store until a solution to the problem is found on HUMAX.

After replacing the TsBKE, it is necessary to perform the training procedure (entering parameters) and automatic configuration of the TsBKE using the Grade-X diagnostic device. You can also view error (fault) codes using this device. You can get acquainted with the functionality of the CBKE in more detail, as well as its diagnostics, using the TI (device, fault diagnosis of the CBKE).

_x000D_

On the one hand, this functional device allows you to more finely tune the operation of the electronics. On the other hand, the unit has a complex structure, which makes independent repairs more problematic. If the TsBKE fails, you will have to contact the dealer, because It is unlikely that the necessary equipment for programming or diagnostics will be at hand.

Attention! It is impossible to retrain a CBKE taken from another vehicle.

Which implementation do you like best? The presence of a simple circuit, where there are turn relays, ESP, etc., or the presence of a central electronics control unit?

Background

This situation arose with one of the Drive members, who is known there under the nickname Schoolboy11, with his Lada Vesta Red Menace car.

After purchasing Vesta, he decided to replace the size lamps with two-pin LEDs. He approached the choice of diodes responsibly - he purchased high-quality, proven products that were selected by professionals. Naturally, with them the exterior of the sedan was completely transformed.

Vesta looks much cooler with LEDs!

Problem

However, difficulties began very soon. One “fine” day, the dimensions on his car burned out, everywhere. Naturally, he tried to install standard lamps, but this did not help. As you know, in such situations everything is usually limited to replacing the fuses for the left and right side lights, which in Vesta’s manual are indicated by the symbols F16 and F17.

However, if you remove the cover that covers the fuses, the owners will find one very unpleasant surprise - fuses F16 and F17 are not there. There are not even contacts - just technological holes.

The cover that covers the fuses.

Separately, it is worth mentioning the lid itself. It is made the same as on Grant - from hard plastic. Moreover, plastic clips do not look very reliable and, as practice shows, they break quickly. On the other hand, the lid is equipped with a foam insert that serves as sound insulation.

AvtoVAZ prescription (unlocking circuits in EMM)

The EMM unit goes into defense. To unblock channels:

1. Without removing the block from the EMM block, connect the connector with the wire to the white block, pin 3 (free).
2. Connect the other end of the wire to the glove box illumination block (green wire).
3. Turn on the ignition for 2-3 seconds.
4. After turning off the ignition, remove the wire connection.
5. Use Grade-X to clear errors in the EMM block.
6. Check the functioning of the previously blocked circuit in the EMM unit.

Apparently, to unblock the circuits in the EMM block, you should apply 12 V to the 3rd pin of the EMM block for 2-3 seconds. Then reset the errors using a scanner, and this can be not only a Grade-X scanner. The order was posted by one of the users of www.lada-vesta.net.

The EMM unlocking process is also shown in the video:
