I measured the voltage between the alternator's output terminal and the battery's positive post with the engine running and loaded ( headlight on, ac on ect). The voltage was 0.22 volt
I measured the voltage between the alternator's housing and the battery's negative post with the engine running and loaded ( headlight on, ac on ect). The voltage was 0.06v.

Also I measured the voltage between the positive terminal of the starter and the positive post of the battery when cranking the engine ( I push all the way down the gas pedal to prevent the engine from starting) the voltage was 0.1 vot

i measured the voltage between the negative terminal of the starter(case) and the negative post of the battery when cranking the engine ( I push all the way down the gas pedal to prevent the engine from starting) the voltage was 0.26v
are the numbers in spec if yes what the next step please?

The linked file contains the complete diagnostic steps for the P0562 code.

What is the battery voltage with everything off?

What is the alternator output when you full field the alternator (Turn on lights and stuff)?

What is the battery voltage when you crank the engine over?

How many amps is the starter drawing when cranking?

When I crank the engine over the voltage is between 10 to 11 volt
the voltage when everything s off is 12.4
the voltage when the alternator is loaded is 13.9 to 14.0 volt

You've got a cell dying. 10 is the absolute lowest you want to see it while cranking. See if you can pop the covers off and add electrolyte. The best thing to do is to boil some water and collect the condensate. Or, bottled water. Last option-tap water.

I went to autozone and they did battery check. Alternator check and starter check and all of them passed?

So they say. 10V under load is a bit low. It's still within the "acceptable" category, but at the very bottom of it. Like, another tenth of a volt and it becomes unacceptable.

Most of those are related to a low or no voltage present condition. The U0101 tells me you've got a bad PCM.
