I have 2003 Dodge RAM 1500 4.7L V8

Battery is good
Alternator new and been tested in the bench and it's working
new PCM

still getting this code P0622

any idea how to fix this problem cause it seams like the alternator is not charging the battery which means i have to drive using the battery only.

Thank you in advance,

Vehicle: 2003 Dodge RAM 1500 V8 4.7L

P0622 Generator field control circuit

If the alternaor and the PCM was replace this problem leaves you with a wiring problem, P0622 are mostly cause when there is a open in the field wire, Another form of P0622 is when the leak detection pump is shorting out,
