Macbook Pro A2442 EMC 3650 The keyboard isn't working.

[citymagua]

Hi everyone. I’m looking for help with a MacBook Pro A2442. The trackpad works fine, but the keyboard doesn’t. We’ve taken measurements and the key voltages are present: PP1V85_S2_IPD
PP3V3_AON_KBD_CONN.
Any suggestions on other signals or measurements I should check? Thanks in advance!

I have also replaced the UT101 and UT102, but I still haven't had any success.

First of all, welcome to the forum!

Any fault history available?
Is your MLB 820-02098?

You should try first with known good trackpad board/flex.
Keyboard sends its information to CPU via trackpad.
