73 System error

When the message "System Error" is displayed on your scooter, it indicates that a problem is detected, but the controller is unable to identify the exact cause. It is therefore necessary to carry out some basic checks to try to locate the origin of the failure.

First checks to be carried out:

✅ Measure battery voltage : A weak or defective battery may be the cause of the problem. Check with a multimeter if the voltage is consistent with the specifications of your model.

✅ Inspect external cables : Look for signs of cuts, loose connections, or oxidation on visible cables. A damaged wire can cause the system to malfunction.

✅ Test the engine by hand :

• If the motor jerks or vibrates when turning it manually, this could be a sign of a damaged motor cable or a controller problem .
• Disconnect the motor cable and retest: if the resistance disappears, there is a good chance that the problem comes from the controller .
• If the motor still struggles, inspect the motor wiring for broken or shorted wires.

If the problem persists

If after these checks the fault remains undetermined, it is advisable to take your scooter to a specialist repairer . A professional will be able to carry out in-depth tests, accurately diagnose the problem, and replace the defective parts if necessary. This will save you additional complications and ensure the safety of your vehicle.
