Cause
Error code 12E (or 12) indicates a problem with the communication between the ECU and other components of the scooter. This could be caused by:
- Loose connection: One or more of the serial connectors (like those for the battery, motor, or display) might be loose or disconnected.
- Damaged connector: A connector might be damaged or corroded, preventing a proper connection.
- Faulty wiring: The wiring connecting the serial connectors could be damaged or broken.
- ECU malfunction: The ECU itself might be faulty, preventing it from communicating properly.
Fix
- Disconnect and reconnect connectors: Disconnect all the serial connectors on the scooter, including the battery, motor, and display. Then, reconnect them firmly.
- Check for damage: Inspect the connectors and wiring for any signs of damage, corrosion, or breaks. If you find any damage, replace the affected connector or wiring.
- Try a different ECU: If the problem persists, the ECU might be faulty. Consider trying a different ECU (if available).
