Perhaps '\', '\i', or '\is' is mapped to something else. Try:

:map \
:map \i
:map \is

Before trying out 'a.vim', for example, I also had:

:map \i :cs find i ^<C-R>=expand("<cfile>")<CR>$<CR>

As pointed out in :h <Leader>, the 'let mapleader' must be done before
the mapping is defined. If 'a.vim' is in your .vim/plugin/ directory,
it might be sourced before your 'let mapleader' was. If you want to
change it, you should have it somewhere in your .vimrc.

It might also be the case that something else is setting mapleader.
Look in the output of ':map' for what is mapped to :IHS<CR>, e.g. in
mine, without setting mapleader, I have:

:map
[...]
n \ihn :IHN<CR>
n \is :IHS<CR>:A<CR>
n \ih :IHS<CR>
