HU55 Entry Ambient Light Change follow IC Design

[maximusmx]

Hi All,
I recently upgraded IC213 firmware to 205 (SuperSport design). Previously my ambientlight can changed follow by cluster design with "Adjust ambient light" option but after upgrade software the ambientlight won't change. Could somebody advise the parameter use to make it work?

Can you show us the coding data for ic213 and alc213 as there is too little information?
Perhaps we can correct the VARIANT coding for either of them.
