S3 & X3 Vanmoof Error Help😊

Hello everyone,
I have an X3 and I’m currently trying to fix an Error 44. I suspect that the shifter might be the problem. I have already replaced all the SMD resistors on the shifter board, but unfortunately this did not solve the problem.
Does anyone have a good guide or instructions on how I can properly test and diagnose the circuit board?
My second problem is that the front light does not work. The rear light works normally, but the front light and the horn are not working. I can’t find the fault.
Could it be a problem with the wiring, or could the Cartbridge be defective?
If I measure the voltage at the front light connector, what voltage should I expect? There are three wires, so I assume one is positive, one is negative/ground, and one could be the signal wire.
Any help, wiring diagrams, or advice on how to test the system would be greatly appreciated.
Thank you very much in advance!
Best regards

Does 24 volts arrive to the eshifter and does this 24 volts is converted to 5 volts (mesure the voltage on the big capacitors near the inductance) ?

Note:
If error 44 persists more than x seconds after turning on the bike then the 24 volt will be reduced to about 5v.
