Is that reading with both charger and battery connected, in off state?
If not, check it now.
Also post PPBUS_G3H voltage in the same condition.

"pin 9 is 0,5v and pin 15 is 0"
Something is strange there, AMON is too high; battery doesn't seem to sink current.
So check again R7021/22 and their traces to ISL6259 and R7020.
Also check pin9 without battery connected.
