Light switch position.

- 0 = LED full brightness + front parking full power, rear parking and backlight of the plate is off, No backlight of indicators (clocks)

- AUTO: Full LED brightness + parking lights, front dimmed, low beam, board backlight is off

- Parking = Led and front parking lights full power, board lighting works, no rear parking lights, No backlight of indicators (clocks)

-Dipped beam = Led full power, parking dimmed, low beam, parking rear and plate lighting

The led goes out when the indicator is thrown

[KamilPL]

1 error found: 02195-Light brightness controller for switches and indicators (E20) 008 - Incomprehensible signal Frozen frame: Error status: 01101000 Error priority: 3 Error frequency: 1 Internal error counter: 3 Mileage: 165 047 km Time indicator: 0 Date: 2042.14 .05 Time 21:57 56

After disconnecting and reconnecting the cubes to the bcm, the brightness of the lighting is not regulated

[ciclo]

Insert the terminal T73b/4 correctly in the slot T73b/4, if previously there were no faults regarding the (E20 - Dimmer) they do not have to appear now.
The contact terminal has two tabs that hold it to the connector, ... with much love and care open them slightly, a minimum angle is enough. You can do this with a cutter or a fine razor.

Clear the faults with the VCDS.

... and retest with the new BCM coding.


Please, be precise about the results.
- AUTO:
Lights ON =
LIghts OFF =

This is starting to look like a real joke ...

Light switch position.

- 0 = full LED brightness + full front parking power, no license plate light and rear parking lights + right / left turn signal turned off right / left LED

- AUTO = full LED brightness + dimmed front position lights, low beam, rear parking lights, NO NUMBER PLATE ILLUMINATION

- Parking = LED + front parking lights full power and license plate light, No rear parking lights, turning on front fog lights turns off LED lights, + left / right turn signal thrown off right / left LED off


- Low beam = full LED brightness + dimmed parking + low beam + rear parking + license plate light;

Error E20 gone OK, BCM won't respond to the new encoding unless I'm wrong

BCM won't respond to the new encoding unless I'm wrong

It does not mean that, now we are trying to find out if there is a problem in the electrical installation.
Let me check it out, I'll post a new BCM coding soon/tomorrow for another test.

Thank you very much for the video, very good idea!! (more clarifying)

For me it is better that you post the BCM coding as text and not as an image, it makes my job easier. Thanks.

Well, the final conclusion is that your electrical installation is not correct at some point, either original wires were used when it was advised to use "new wires" and isolate the original ones, or the wires are interconnected (drl with parking/side lights wires) due to some trick done in the past.

You must use a multimeter to make sure that the wires are not connected to each other (drl with parking).
When you are absolutely sure that the installation of the wires for the parking lights is as in the following diagrams (1 or 2), contact me again.

1

Note: front and rear share the same wire.

2


These diagrams are a repetition of what has already been indicated for this installation, perhaps it is easier to understand this way.
All possible BCM codings will only work correctly if the electrical installation is correct.

3 DRL

You should also check the new installation of the 5 new wires in the area of ​​the light switch - bcm.
It must be as indicated, it's very important.

While you make sure of all this, use this BCM coding:
7C8829F88861010001200EF06EEB9EC85FC067FF608D30C1200000030000
It is the one that most closely approximates an original and legal condition.

2.5 are ok, 3 should be taken from bcm and insulated? I will finish the work, I will visit the company service and check the correctness of the wiring from the above diagram. Throw advice on how to drag the cables from the cabin to the lamps, I will break the wiring and add 2x2 cables to the front lamps

[ciclo]

Everything will work perfectly as indicated in the diagram I made for you (and everyone).
You make me understand that English is difficult for you because everything is perfectly explained in the diagram. I think that is the problem of everything that is happening.

I am going to explain it to you so that you can use the translator in case it is necessary.


Wires.

1- Remove original T17/16 wire , once remove it, splice a new wire to this removed wire, and connect this new wire to T73b/7. (the T17/16 slot is now empty)
This action will make your license plate lights work properly.

3- In the BCM black connector you have to remove the original T73a/45 wire and isolate it. Now install a new wire from T17/13 to T73a/45.

4- Install a new wire from T17/5 to T17/16.

Easy and simple.

I don't know how the people who retrofit the Ibiza 6J run the wires from the cabin to the engine compartment.

Do some research on it, surely you will find in a retrofit (CCS for example) how they run the wire that goes to the ECU.

The correct thing is that you find the place where the original harnesses run. Look from the engine compartment towards the cabin.

I suppose that the cable routing is +/- identical, I have to remove the wiper motor grills and I will see everything, in your opinion, all the rest of the cables according to the diagram are correct, the problem is 2x2 lamp wires and wiring in the above diagram, point 1,3,4 or look for further problems?


Lamp connectors are the same as for bcm?
How many +/- 0.5mm cabling length do I need?

[KamilPL]

What the f**k is done here .... Cable 4,5,7 cut, bridge t17 / 5 -> t17 / 16 cut, t17 / 16 bridged to T73B / 7. cyclo tell me what the T17 / 7 cable is responsible for, how important it is, I will connect it back (currently cut and insulated),

I do not see the original T17 / 16 cable in the original bundle, because there was a t17 / 5 bridge -> t17 / 16, so what cable should I connect to the t73b / 7?
a f*****g idiot not an electrician


Edit: t17 / 4 (j828 relay) ok

[KamilPL]

I will make a T17 / 5 bridge with the T17 / 16, where do I get the cable from to connect it to the T73b / 7 if it will not be physically in the bundle?

[KamilPL]

The original cable from the T73a / 45 is removed and insulated, but there is no cable in the T73a / 45 to T17 / 13, there is a cable in the light switch T17 / 13 make a bridge for this cable or throw the cable out of the switch and insert a new one ??

[KamilPL]

I have a big problem, I can't pull the cable out of the T17 ankle, do you have a patent for it?
