Trackpad and keyboard not functioning after replacing parts

Coconut Battery
Hi all,
I got hold of a A1502 Mid 2014 Macbook Pro Retuna where the keyboard and trackpad wasnt working.
I’ve replaced the battery and trackpad assembly (with new flex cable), SMC, PRAM reset with fresh OS, but still doesn’t work.
Oddly though, if I hold down Option CTRL Shift and the power button, I can see that this resets the SMC as the light on the charger changes colour. But when the mac is up and running, it’s not working. Odd.
Can’t see any marks of water damage, or know if anything is shorting but not sure how to test either. Keyboard illuminates.
Thanks,
Is this a good question?

Does the onboard diagnostics run without problems or error?
Restart your system and press the D key to enter into it.

Hi Dan,
I can get into diagnostic with external keyboard, in the diagnostic it doesn't work still and comes back with the error;
There may be an issue with the trackpad
Reference code NDR001
There may be an issue with the keyboard
Reference code NDK001
Also to add I get the error "battery needs service PPT004" but I don't get any errors at all on the OS itself.
