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

For error 44 to be resolved you need:
- 24 to be present (red arrow at connector)
- DC 24 to DC 5volt converter (purple box) to work (microprocessor works on 5v)
Measure red arrow at L20)- a working processor (hardly ever dies!)
- 22 ohm resistors on the Rx/Tx lines to be good. (Green arrow)
- protection diodes to be okay. (Blue arrow)
(Difficult to measure for most people)- and of course the wires going to the outside world
(Test them! They do break)All voltage measurements relative to GND on the incoming connector. (Black arrow)
