Deactivate GHAS on M2/M3/M4 - Airbus - 11-08-2022
Is there a solution to remove the GHAS completely out of the "vehicle"?
I fdl-coded GHAS, DSC and ICM and removed most of the fault memorys but there are still two entries left in the DSC but nothing to code anymore regarding the HAS System
Did any1 get it working?

Noone any ideas?

Have you disconnected the ghas ecu in the trunk?
RE: Deactivate GHAS on M2/M3/M4 - Airbus - 17-08-2022
Yes, I tried that too but still errors

Some people say that it is doable via coding, however I managed to do it by using emulator, coding didn't help.

if you have coded correctly DSC and ICM Ecu maybe you need to check the Kombi Coding
When you have correctly disabled you'll have always an error in ista when you diagnose the car, but on the cluster no problem at all.
i've done it 2 m2 comp with this method because they swap the oem Elsd with a mechanical Lsd.

Didn´t code the Kombi. But the error comes from the DSC.
Do you have the fdl-flags you successfully changed for me?

Yes, the error comes from dsc but you have to remove it in kombi, the error in the dsc can’t be removed.
I’m out of my workshop until the 29, if you have patience i can send you the cafd after this date.

I've done it on F87 comp, F82 and F10 M5 before. All replaced with OS Giken Superlock mechanical diffs.
It requires changes to the ICM, DSC and KOMBI coding. You'll always have a permanent error in the DSC module (Missing message QMVH rear axle torque distribution) when reading fault codes but no fault on the dash. DSC will still be fully functional. MDM, dynamic brake control, ABS and other DSC functions will operate as before.
Please PM me for more info.
