You’re trying to do ForScan mods, these aren’t Sync3 issues.
The climate control not working means you either have incompatible firmware in the FCIM or the climate repeater is set wrong.
The auto start/stop symbol means not available which can happen if: 1) the cars 12v battery is weak; 2)the BMS wasn’t correctly reset after the battery was replaced; 3) the car has a manual button to enable/disable the function

What is the FCIM?))

By Forscan I need to check climate repeater settings, can you advice in which module I can find them??

Battery power in:
sleep mode(vehicle engine off) 12,8V
Working mode (engine work) 14,4V

Battery wasn’t changed, just disconnect for 35 min.

What is BMS??

Manual button ON.

The BMS (Battery Management System) should be reset after every battery change.
It resets the battery days in service back to zero thus ‘telling’ the technology how the new battery should be charged.

If it is not reset you can possibly get issues including spasmodic functioning of the stop/start ‘feature’ because the car’s system still ‘thinks’ it is dealing with the old battery.

Also the battery needs to be fully charged for the stop/start system to operate as indicated earlier.

For the climate, check the Corsair or Kuga forums and look for ForScan info, you may find something on fordescape.org as well.
Typically if you have a physical manual start/stop button you cannot enable it on the APIM screen.
Keep in mind that any changes made with ForScan can cause other issues, just because you can change things doesn’t mean it will always work correctly or have a positive impact.

Hallo everyone.
Problems solved.
Maybe will be helpful for others, what to do:

1. Auto start/stop - restart BMS or BdyCM module (in Forscan). Without adapter, very easy:
   Ignition ON(Engine OFF),
   5 times flashlight,
   3 times brake,
   Battery indicator should be flashing, then steady.

2. Climate control on SYNC 3.4 & time on main screen - need Adapter (was used ELM327 HS/MS Can) & Forscan:
   Configuration → Module APIM → Climate
   control Strategy → North America (don’t switch to Europe, as the SYNC 3.4 not fully adopted for Europe)

Added screen where to find. But in Russian language.
Thanks for everybody and good luck ))
