G30 No communication with FlexRay modules after coding.

dominikmazurowski · Jan 19, 2024

Hi,
I was coding EU radio frequencies to my US spec M550i, by mistake I pressed 'code' instead of 'code FDL' in Esys. After a few days, I realized that ISTA won't connect with modules connected via the FlexRey bus.
I saw a few posts about this issue, but unfortunately, I lost a copy of the SVT file backup.
Could someone guide me what is the procedure to fix it? I'm attaching a few photos from Esys.

I saw this thread, but I'm not sure if the described procedure by @@shawnsheridan will help.

Write svt back to vcm. If you doesn`t know how to write me pm I can do it over teamviewer

Would you be so kind as to give the explanations here? The solution could be useful to more people if you are so kind, thank you.

No need for battery charger,
Calculate svt taget. Load it in VCM section. Write SVT target to vcm

Like TheNine90 said
1. Go to "Coding" mask, in the right tab: select "full calculation", choose correct i-Step shippment and i-Step target.
2. Then press "Calculate SVT"
3. Save calculated SVT as "target.xml"
4. Go to "VCM" mark
5. Choose saved on step 3 file as "SVT target"
6. Go to "Master" tab, press "Write SVT"
7. Go to "Backup" tab, press "Backup data"
8. Reboot car
Enjoy
