820-00165 does not recognize ssd

[andrespi]

This computer does not detect ssd good condition in disk utilities

corrosion C8070 and around U8070, clean U8070 and change c8070

these are some measurements whith ssd inserted

U8070
PP3V3_S0SW_SSD_FET_R=2.5
PP3V3_S5=3.3v

U3740

pin 1 PP3v42_G3H: 3.447V
pin 2 P3v3SSD_VMON: 0.73
pin 3 SSD_RESET_L : 3.291V
pin 4 SSD_RESET_CONN_L : 0V
pin 5 0V
pin 6 SSD_PWR_EN: 3,2V
pin 7 SSD_CLKREQ_CONN_L: 2.4V
pin 8SSD_CLKREQ_: 3,288V

Change U8070 first.

"pin 7 SSD_CLKREQ_CONN_L: 2.4V"
This must be 0V, pulled down into SSD.
So check SSD connector and traces.
