[TUTO] Télécodage et calibration d'un NAC / RCC / CIROCCO / CMB_NUM SANS Diagbox via Arduino

Could someone help me activate ACC in MG1CS032?
I've already done everything in the other ECUs, but I can't write to this one.

Hi, it looks like you have the same issue as I do. I tested the config from @JonnyMnemonic, and it seems they used the zones configuration from CMM_VD56 and modified my config accordingly. I think you could try the same approach.
For me, this actually worked — I managed to eliminate the error about missing communication with the engine ECU. However, I still get a message about "Activation not possible due to conditions" This probably means I haven’t configured something yet.
 


As has been mentioned before and in other forums, this type of control unit cannot be modified because it includes a manufacturer's protection system. Modification will only be possible by the manufacturer, depending on the case. This system is currently implemented in several BOSCH control units, as far as I know, to prevent modifications to the engine's ADA and anti-pollution systems. I don't know if it will be possible to bypass this protection in the future.
 



First, you have the wrong shift lever for manual mode. This is probably why it doesn't work because your shift lever doesn't have the appropriate CAN command programmed into it.

Voir la pièce jointe 41402I retrofit the car from M to P, and made the codings, now the car park automatic.My friend have this function from the factory (with P) and when he wants to shift manual select this from drive mode button,I think i have to code something but I don't know what and where.

salut tu peux m’aider svp j’ai une peugeot 3008 Gt 2021 Diesel Eat 8 j’ai eu un problème après avoir fait la procedure de Drive Assist l’angle mort ne marche plus quand je met On ca reviens sur OFF
salut, l'as-tu resolu? j'ai exactement le meme probleme, apres l'activation du park assist, l'angle mort ne marche plus et reviens sur "OFF"
 

Hi guys, I'd really appreciate any help. I have a Peugeot 308 T9 and I need to enable the DSP function in the power steering DAE_BVH2. Here's the code in my car:
>6B5:695
81
21A0
:2305:83:C0
61 A0 03F0FF 0802000001

What code do I need to enter to activate DSP? Thank you.

Ok here’s the update from my 3008 which got upgraded from the old 8” screen with a wave 2 to a 10” with a wave 4.
I uploaded the calibration file and updated the 212A value with the new restyled one.
Did the steps as instructed by Vlud and the camera image is now fixed! :-)
Thank you Vlud for the help.

I do have ONE last little problem, that I hope you can help with in some way.

Beside the camera problem, I also had problem with echoing when calling from the car.
I read before in the forum that this was due to a wrong calibration, and since I’ve been running a custom calibration I thought, it must be because the calibration is wrong.
So since Vlud just posted the calibration for the new restyled 3008, I was hoping that it would finally fix that problem as well.
But unfortunately that was not the case, the problem is still there.
So I got curious, and examined the file provided by Vlud and my custom calibration file, and they are identical. So I guess that this calibration is an adapted version but not the Real one extracted from a restyled 3008.

If I got access to a new 3008 restyled, what would it take to extract the calibration from that? I couldn’t seem to find the steps required with arduino to extract it from it.

What are your inputs? Do you think it will fix my problem if I get the “real” calibration?
In theory it should right?

Thank you in advance.
I'm having the same problem, can you help me?
 

Bonjour,

J'aurai besoin d'aide de la communauté... 😊
Sur 208 avec NAC W2, j'ai installé une camera pano 180° et mis à jour les zones 2105 et 212A.
La camera se déclenche bien en marche arrière, par contre la vue est écrasée en horizontale et mal centrée.
Impossible de faire prendre en compte les valeurs de la zone 212A au NAC W2.
J'ai essayé l'apprentissage auto avec Diagbox 9, et également le rafraichissement via commande Arduino (static 3101DF09), mais rien n'y fait.

@VLud m'a indiqué que les NAC W2 sont récalcitrant à prendre en compte la zone 212A, contrairement au NAC W4 pour qui ça passe très bien.

L'un de vous aurait réussi la prise en compte de la zone 212A sur NAC W2 avec cam 180° ?

To fix the echo problem, you need to update calibration, try one from hybrid, worked for me.
To fix the camera: read a NAC address 021A, answer would be 0 or 1, you need to write there the opposite and then rewrite back the original.
Code:
>764:664
1003
22012A -> returns value 00 or 01. (6E012AXX)
:D91C:03:03
2E012AXX -> opposite of the read
1001
reboot NAC
>764:664
1003
:D91C:03:03
2E012AXX -> original
1001
 

Thank you for your reply. My problem is that the rearview camera's viewing angle is too low. I will follow your instructions and respond with the results soon.

Hey guys, little bit of a random question. I want to install a custom headunit in my car (2018 308 GT with Denon amp), but I'm looking into not removing the NAC, as outputting audio directly from the headunit to the Denon amp is not feasible (lots of noise). My headunit can output audio via USB, so my plan is to connect the headunit to the USB port in the NAC and output from there. My only doubt is (as I won't have the NAC screen) if there's a way to make the NAC default to USB audio input. Maybe disabling radio, android auto / carplay and etc? Does any of you guys have any experience with this edge case? Thanks in advance!
 

Hello @jweber018

I don't understand "Output audio by USB" ?!
USB is data connection. Not analogic for input/output audio signal.

Why don't you use the auxiliary input ?
 


you can activate aux input.

Hi to all! I've changed my Corsa F rcc to nac (coming from another Corsa F) but I'm currently having three main problems:
1) Color artifacts in android auto
2) Electrical interference in the audio system
3) Even if coding the language setting as Deutsch when I factory reset the unit always go back to english
Do you have any suggestions? Thx in advance

Hello everybody!

@VLud thanks for the great pioneer work.

Is it possible to change IVI config on a car thats on nae2020? (2024 3008).
Factory original IVI that came with the car.

I want to activate seat cooling function on the screen.

When I try to open the parameters, I get an error:
"Index and length must refer to a location within the string. Parameter name: length"

This tools is only for NAC/RCC. It's not working with IVI

Hello, the NAC on my 5008 Wave 2 is broken. I replaced it with one taken from a 3008, but the image on the reverse camera doesn't match reality (the actual distance is much smaller than the distance measured on the NAC). I tried changing to different 5008 .Cal files but without success. Finally, I bought a NAC from a 5008, and it works perfectly. Does anyone know what the problem was?

Hello everyone. I activated the ACC system in my c5 aircross vehicle. I had tried this many times before but I found that the ESP90 ECU was incompatible. I replaced it with an ESP90 ECU from another C5 aircross that had ACC and ACC worked. There were a few other faults. I solved all of them by coding except for 1. The system is currently working actively but there is a C1383 - Brake Fluid Level Sensor - Open Circuit - Permanent error. Therefore, when I start the car, it says stop the engine and brake fault. Does anyone have information about this? According to my guess, my previous ECU was working with level sensor on/off. This ECU expects the sensor to work according to the resistance value. I can only guess that this may be the fault.
I think you are right on that one. Have succeed? Thanks
 

Hello everyone,
Does anyone here know if it’s possible to enable ACC (Adaptive Cruise Control) on ECU MD1CS003?
Here is my zone 2101 configuration:

I have already enabled ACC in RADAR_AV4 and CVM3 ...... However, I still get the error “Automatic speed control fault” on the cluster, and in Diagbox the radar shows a message about missing communication with the engine.


In the MD1CS003 engine ECU configuration I can’t find any option related to ACC.
Does anyone have any knowledge or ideas about this?
I'm fighting the same problem with engine ECU EC5 v46.6
