Good signals, no need to change it.
Good enough to short R5150 pads, when in doubts.

Check UD200/1 SCL/SDA lines; voltage and diode mode to ground.

For UD200 /
pin 2 : I2C_SMC_PWR_1V8_SCL : 0.520 in diode and 1V78
pin 3 : I2C_SMC_PWR_1V8_SDA : 0.553 in diode and 1V78
pin 4 : I2C_SMC_PWR_SDA : 0.377 in diode and 1V22
pin 5 : I2C_SMC_PWR_SCL : 0.032 in diode and 0V

Abnormal for pin 5 i have replace UD200 and RD200 same

have replace UD201 and now have 3v3 on I2C_SMC_PWR_3V3_SCL
i see the percentage now but when plug charger don't charge
i have 19V and when start and logged bettween 0.165A and 0.3A

"SYS_DETECT_L : 3.28V after replace UD201
.............................
SYS_DETECT_L : 0V"
When I should believe you?

"i have 3.2V on pin 5 J5150 only whith battery connected"
It must be always 0V; make permanent short on R5150 pads.

"When I should believe you?" Yes because when battery is plugged on pin 5 J5150 i have 3.28V but on pin R5150 i have 0V is strange
I have make permanent short on R5150 and same. Not charge too
