      'ACTIVE'=>'Y',
    'DEPTH_LEVEL' => 3,
    );
$rsResult = CIBlockSection::GetTreeList($arFilter);

while($arResult = $rsResult->GetNext()){
   $arResult["ID"] = $hi;

Nothing is displayed on the screen. I don't use any components.

Add somewhere above:
And it will become a little clearer. And so at a "look":
You assign an undeclared variable in a loop to each element:

while($arResult = $rsResult->GetNext()){
   $arResult["ID"] = $hi;
}

And then you try to use a scalar (which doesn't exist) as an iterator... What do you want from such code?
