PM_PWRBTN_L 3.42 to constant 0,352V when SMC_ONOFF_L is triggered

820-00165-02 PP3V3_SUS 3.3v PM_BATLOW_L 3.3v

Suddenly it stopped starting. Stuck 5v. I replaced CD3215A10. I can't complete DFU revive without error

Mac is stock on 20V 0.3A. Its stuck in recovery mode in Apple configurator 2. It begins installing the system using system restore. The outputs "failed to recive message from device, might be a connection problem with usb host) [AMRestoreErrorDomain - 0x9 (9)] SLPS2R I AWAKE are present What to do ?

Hi guys this time I have a 820-00163 board with no water damage or corrosion. I checked: PPBUS_G3H 8.6v PP3V42_G3H. 3.43v PP5V_S5 5v PP3V3_S5. 3.3v PP5V_S4RS3. 0v PLT_RESET_L 0v PM_PCH_SYS_PWROK 0v SMC_ONOFF_L 3,43v PM_PWRBTN_L 3,42v PM_SLP_S4_L 0v PM_SLP_S3_L 0v

Sorry for the confusion. I replaced Q7155&R6950 and still the same

Only battery PPBUS_G3H 0v 3V42_G3H 0v

I changed the batteries. MacBook sees the battery, will charge the battery until full but will shut off immediately if it is unplugged from the AC adapte.

Yes. PP3V42_G3H - 3,42 v

I replaced the D7105 and it starts but will not power on with battery power. C7116: pin 1 - 1,4 v pin 2 - 8,6 v R7151 and R7152 pin1/2 - 8.6 v I tried a new battery and a pram reset.

PPDCIN_G3H 16.2 PPDCIN_G3H_ISOL 16.2 But diode mode F7140 pin 1 - 0,125 pin 2 - 0,460 Is it just a burnt fuse ?

I noticed that ppbus grows slowly from 0.6 to 1.7

I replaced U7100 and R/D7105 1- 0 2- 5.4 3- 4.3 4- 3.3 5- 1 9- 0.03 12- 3.4 13- 3.4 15- 0.04 17- 8.6 18- 8.6 19- 5 20- 5 27- 16

I'm changing U7100. PPBUS_G3H 1.2 V U7100 voltages: 1- 0 2- 7 3- 4.3 9- 0.03 12- 3.4 13- 3.4 15- 0.03 17- 8.5 18- 8.5 19- 5 20- 5 27- 16

diode mode 3 - 0

The short was on c7314. Now: PPBUS_G3H 0.4V U7100 voltages: 1- 0 2- 15.6 3- 0 9- 0.02 12- 3.4 13- 3.4 15- 0.04 17- 0 19- 5 20- 5 27- 0

4v and nothing. Can I give more volts ?

Big coils are good, the closest are: L7310 - 12 ohm L7320 - 12 ohm

The board is clean, However, I have a short to ground on: PPBUS_G3H,0.9-0.4 ohm PPBUS_S5_HS_COMPUTING_ISNS 0.9-0.4 ohm PPBUS_S5_HS_OTHER_ISNS 0.9-0.4 ohm Is the CPU dead ? What to do ?

Thank you for your help. I reflash UB090 and ordered a new CD3215 again. It helped
