7. Fehlerbehebung
7.1 Fault Code Persistence
Ausgabe: You clear a fault code, but it reappears immediately or shortly after.
Lösung: Clearing a fault code only removes the code from the system's memory; it does not fix the underlying problem. If a fault code persists, it indicates that the hardware fault still exists in the vehicle. It is crucial to diagnose and repair the vehicle's physical issue first before attempting to clear the fault code again. Consult a qualified mechanic if you are unsure about the repair process.
7.2 Gerät lässt sich nicht einschalten
Lösung: Ensure the device is fully charged. Connect the charger and wait for a few minutes before attempting to power it on again. If the issue persists, contact customer support.
