What It Means
The "LCD Signal Abnormal" error indicates an issue with the communication between the LCD display and the controller. The bike's LCD is unable to send or receive data correctly, which may prevent certain functions from working or display incorrect information. This error is specific to Pedego's Element electric bike.
Possible Causes
- The connection between the LCD and the controller is broken or loose.
- The communication circuit in the LCD is faulty.
- The communication circuit in the controller is faulty.
- A 5V circuit inside the controller may be damaged.
How to Fix It
- Inspect the LCD connection – Ensure that the cable connecting the LCD to the controller is properly plugged in at both ends.
- Test the cable – If the connection appears secure, unplug and re-seat the cable. Check for signs of wear or damage on the cable.
- Replace the LCD – If reseating the cable doesn’t resolve the error, the LCD might be faulty and require replacement.
- Check the controller – If replacing the LCD doesn’t fix the issue, test the controller. A damaged controller may need to be replaced.
- Test for a short circuit – Disconnect other components (e.g., throttle, motor) to isolate any potential 5V circuit short causing the error.
Preventive Measures
- Regularly inspect cables and connections for damage or wear.
- Avoid exposure to water or moisture around the controller and display.
- Ensure cables are secured and not subject to excess bending or tension.
When to Contact a Pedego Technician
If these troubleshooting steps do not resolve the error, contact a Pedego technician or authorized dealer to diagnose and repair the communication circuit between the LCD and controller.
