Test first disconnecting webcam.
If still low, try known good trackpad board/flex.

Check if R5260/61 are good.
Also test removing R5222/23.

Do you get only one error in ASD?
Run it in Continue mode.
That error is still related with trackpad (Palm Rest temp sensor).

Change the motor; see if other errors disappear.
Try another trackpad flex/board.
Inspect trackpad connector pins.

Motor errors still present after changed it?

Check R5270/71.
Post diode mode to ground on their SCL/SDA lines.

* check it R5270/70 1K
* R5270 PİN2 / SDA = 0,532
* R5271 PİN2 / SCL = 0,562
* I changed the motor, same result.

Looks like big diference on that bus; compare readings with similar board.

So you still get motor related errors after changed the motor?

yes same error
yes same error

asd is very slow working , takes 1 hour

different cards have different values, what should i understand from this ?

Diode mode

820-3115b = J5800 PİN 19 = 0,708 PIN 17 =0,609

820-2936B = J5800 PIN 19 = 0,561 PIN 17 = 0,532

Yeah, the first error is about right fin stack proximity (Th1H), not palm rest.
Pay atention when you read the ASD messages!
Check Q/U5520 areas.

Your machine has only one fan, I don't understand how do you get messages about two fans.
In fact, left fan is reported as OK.

I suppose you didn't use proper ASD version.
Try ASD EFI 3S144.
