MacBook Pro 13" M2 No trackpad click high fan spin

[Stephen]

Board powers on and display turns on, battery holds charge, I know the trackpad is the issue, replaced the trackpad with new M2 trackpad and cable since they were burnt, also replaced the connector on the board good as new, pins are getting power, however since I do not have the schematic for this and cannot seem to find it, can someone point me in the right direction to get this trackpad working and also maybe provide a M2 A2338 schematic?

I have no power on these pins so far
7,11,12,27, 29,41
pin 25 is .5volts which is low. Need schematic to pin point the short so I can get this trackpad happy.


update: found the schematic on here. I’ll come back with my findings

So no click on track pad still, cannot seem to find the short that is causing this trackpad to not click which will cause the major fan spin and the keyboard to not function (from experience)

I am getting voltage on the PPBUS_AON pins without issue. But I am not getting voltage on pins as follows

Pin7
Pin11
Pin 12
Pin 25 (.5v) is being shown which is in my suspicion low.
Pin 27
pin 29
Pin 41

Remove all power. Measure the resistance to ground of pin 25.

[Stephen]

Nothing coming up from pin 25

What is the resistance to ground on pin #25?

[Stephen]

No readings coming up for pin 25 with resistance to ground
