Normally, the word moha is used to describe those who have ten types of wrong views (miccha ditthi).
– That is the strongest level of “ignorance.”
When those ten types of wrong views are removed, one gets to mundane Samma Ditthi.
But one has not comprehended the Four Noble Truths (or Tilakkhana) yet.
– Thus one still has avijja, a lower level than moha.
That is why the akusala-mula Paticca Samuppada process starts with, “avijja paccaya sankhara“. It ends in “the whole mass of suffering.”
To remove avijja, one must first learn them from a Buddha or a true disciple of the Buddha, of course. Then one must contemplate on what is learned, and comprehend the “anicca nature.”
– That is the “previously unheard Dhamma” until a Buddha is born.
The kusala-mula Paticca Samuppada process comes into play ONLY after the comprehension of Tilakkhana.
– That process DOES NOT lead to “the whole mass of suffering”. It ends with “Dhammanam samudayo hoti” and leads to only Ariya births (i.e., as a Sotapanna Anugami or above). Whehter one is reborn a human, a Deva, or a Brahma, one WILL BE an Ariya.
