Crack The Code Puzzle

Question

During a secret mission, an agent gave the following code to the higher authorities

AIM DUE OAT TIE MOD

However the information is in one word only and the rest are fake. To assist the authorities in understanding better, he also sent them a clue – If I tell you any one character of the code, you can easily find out the number of vowels in the code word.

Can you find out the code word?
