Amarok codes

Good morning people, someone has the description of the Amarok FF fault cod
, A9, 15
FF, 90, 8b, 71
and FF, 92, 34, 71
gives them as specific to the manufacturer, and I don't have the description.
Thank you very much

Hello where do you get those codes since the DTCs if they are of electronic injection begin with the letter p xxxx and four numbers

Vehicle software version: V28.21 Diagnostic application version: 3.10.010 Test Test: 2017-10-21 08:23:56 Diagpath: System selection> 08 Air conditioning/heating Result of the diagnosis
FF, 90.8b, 71 Please check before proceeding passive/abiogenesis
FF, 92,34,71 please check before proceed Liabilities/Abiogenesis
FF, 90, A9,15 Please check before proceeding active/statical

This is what the lunch throws me, and when you look for them it tells me that they are specific to the manufacturer.
