Damaged cable
Pinched, kinked, or damaged cables can cause signal and communication errors.
Moisture or dirt
Moisture, dirt, or corrosion on contacts can impair the electrical connection.
Defective component
If wiring and plug connections are in order, a component itself may also be faulty.
Important Safety Notice
Error codes often concern electrical, mechanical, or safety-relevant components. Work on the battery, controller, motor, brakes, wiring harness, or plug connections should only be performed if the necessary expertise is available. If unsure, contact WANDLER Service or a qualified specialist workshop.
