3. Check for:
   • bent pins
   • loose pins
   • contamination
   • moisture

If bent pins are found

Carefully straighten the pins if safe to do so.

Reconnect the display and test again.

If the issue remains

The display may require further inspection.

Please contact support.

If the pins appear normal

Inspect the controller and junction box wiring.

Step 3 – Inspect controller communication wiring

1. Open the controller compartment cover.
2. Locate:
   • the XHB8 connector between the display main line and junction box
   • the SM yellow/green 2-pin connectors between controller A and controller B
3. Gently check whether:
   • red wires are loose
   • yellow wires are loose
   • connectors are incorrectly connected
   • pins are bent or contaminated

If loose or incorrect wiring is found

Reconnect the wiring securely and test the scooter again.

If the issue remains after reconnecting the wiring

The controller system or display main harness may require further inspection.

Please contact support with:

• Photos of the wiring
• A video showing the E30 error
• Photos of any visible damage

The throttle may require further inspection.

Please contact support.

If the connector appears normal

Inspect the green wire connection at the XHB8 connector.

Step 3 – Inspect the green wire connection

1. Open the controller compartment cover.
2. Locate the XHB8 connector between the display main line and junction box.
3. Gently inspect the green wire connection for:
   • looseness
   • incorrect wiring
   • bent pins

If loose or incorrect wiring is found

Reconnect the wiring securely and test again.

If the issue remains after reconnecting the wiring

The controller or display main harness may require further inspection.

Please contact support.

E05 – Undervoltage Protection

What This Error Means

E05 indicates the scooter voltage has dropped below the protection threshold.

Possible causes include:

• Battery fault
• Incorrect P8 voltage setting
• Controller fault

Step 1 – Charge the scooter fully

1. Charge the scooter fully.
2. Confirm the charger operates normally.
3. Test ride the scooter safely.

If the scooter operates normally after charging

The issue was likely caused by low battery charge.

Continue monitoring battery performance.

If the scooter quickly loses power again

The battery may require further inspection.

Please contact support with:

• Charger behaviour video
• Battery percentage before and after riding
• Approximate riding distance achieved

Step 2 – Check the P8 voltage setting

Inspect the P8 voltage setting on the display.
