Problem with 4WD Isuzu D-Max 3.0

What is your problem and what year is the car

The same thing happens to me ... that is to say the check4wd is activated .... This happened when the battery was left without load ...... It also happens to me that the battery does not charge enough, I checked the alternator and this ok, I changed Correa but it is still the same ... I do not know what it can be ...
it is 2005.

What old is the battery? , The acid of the cells are empty? The terminals are dirty? Do you have current theft due to the installation of any accessory? Approximately when Kizas failed from Ke, did you take him to a workshop for any reason?

Thanks for the solution ..... many questions few answers .... The main theme here was 4x4 the battery is the least.
Thanks anyway for your availability. But I already solved the subject.

I needed to know well what it was what I was happening to you, I bought the manual and it cost me 285.00 gringos dollars and I cannot give a great information just like that because I bought the manuals until 2008 and they are charisimos then I just wanted to know if you were worth giving you such information but it seems that I do not, I have offered free information for all the friends of this forum Given information I have always had to pay if it is not the original amount a part as thanks and what I will charge in my work in the future and wisdom is priceless and apologize for bothering you with my questions
