What the hell is byte 74

Sent from my Pixel 3 XL using Tapatalk

All the options you see in the proxy alignment screen are just "helpers" to modify the according byte(s).

Not all the options are available in the screen - if you know what to change, you can access the byte sequence manually via CTRL+C in the proxy alignment screen.

but ATTENTION should NOT change the bytes without being sure what they are doing

Absolutely.

You might end up turning your car into a diesel or Stelvio [emoji12]

 

[MacGeek]

Technically you could really end up turning it into a Stelvio as far as the infotainment system is concerned, the firmware contains both car graphics and the displayed ones are dictated by a proxi setting...

I was expecting (and hoping for) such a comment from you

On topic:
I've just tried it - without success.
To begin with; my car had "A3" and not "A7" at byte 74.
After changing it to "AB" and executing the proxi-alignment the menu option did indeed show up.
However - every time I changed the option to "On", it would default to "Off" again after a few seconds.
All of that while the easy entry was still working (as before).

So in summary: functionality was unchanged, but I enabled a useless option

I'm in the process of returning everything back to normal right now.

Tell me you have blind spot monitor ?
If yes you have only visual or visual + acoustic ?

Yes - I have the blind spot monitor.
I have seen the triangle in the mirrors, I'm not sure about the acoustic warning however.

Rear cross path detection is also working fine. (No idea if that's relevant)

This is a video as you can see is a 2016 giulia with acp/aa , easy access menu and blind spot monitor with acoustic and visual alert

But this car was fitted with a 2nd gen infotainment-unit, correct?

Regarding AA/ACP:
What exactly has to be changed in the proxi-config?

 

[ratix]

Yes second generation
All I know is giulia/stelvio 2016 2017 ( H in vin number ) has to be changed internally and proxy change

We would great appreciate if you can provide more info a step by step to do this for "H" VIN cars. Can you find the exact procedure from your friend? Thx

 

[ratix]

After several updates the system cross lane departure warning now have this sound

In my opinion more cool

Hey @ratix,
If you cant give us the exact procedure for the H cars, can you at least show us a screenshot of your "Ctrl+Alt+C" screen with the codes in MES under the Proxi Alignment Procedure Page? Maybe some of us can decipher them.

This is what a procsi read out looks like: i don't know which position the H from the VIN is though. 2017 Q4 with latest USB and ETM:

30 34 36 32 31 30 31 36 37 32 35 4F 55 54 50 55 54 2D 53 49 54 20 17 03 24 4F 0C 40 65 10 40 19 02 0A 00 00 00 C0 00 00 00 4B 0C 00 65 10 40 19 02 0A 00 00 00 C0 00 00 00 41 5A E7 01 C9 82 07 F3 54 31 A1 07 40 10 30 0A A2 20 04 72 00 FF 63 28 00 43 C2 B8 1D 83 AC 48 45 43 05 00 80 00 0C 4E 00 00 1A 04 00 89 00 5B FA 02 07 F5 05 31 20 09 72 14 3D 81 10 7B 00 EA 00 BB 10 10 A0 3D 49 03 03 3A FF 5F 81 00 01 01 00 00 F0 20 08 20 02 0A 00 00 00 04 00 0C 1C 00 00 00 50 30 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

I've tried looking for a sequence of numbers as mine is H755 to see if I would find some sort of pattern, but cannot. I do have a sneaking suspicion that if you even change the VIN in the BCM procsi, it may cause the ETM to show a mismatched VIN and ask for a security code on the radio.

If they are doing standard ASCII to hex encoding, "H" = 48

 

[Beta Romeo]

If they are doing standard ASCII to hex encoding, "H" = 48

Interestingly I had put if through a Hex to ASCII converter(so at least some of it is in common ASCII). and clearly you can read "OUTPUT" in the conversion:

04621016725OUTPUT-SIT $O@e@
ÀKe@
ÀAZçÉóT1¡@0
¢ rÿc(C¸¬HECN[úõ1 r={ê» =I:ÿ_ð
P0

I just don't know exactly what to change. Since there is only one H I may try to change it to a J and see what happens, I'll keep you posted.

You could be the first to “brick” an entire car?‍♂

 

[JeFizz]

H or J is the 10th spot in the VIN, not sure where that comes into play here folks. Dancing with the devil I say!!

 

[Beta Romeo]

"You could be the first to “brick” an entire car?‍♂ "

Well, I'm mighty-mighty, just lettin' it all hang out.

 

[lockem]

Try converting the long decimal digit strings of your VIN to HEX and then see if there is a match. Maybe the VIN is not coded as ASCII.
