2. Quick Diagnostic Process: Reading the C10E LCD Display #

The C10E is equipped with a multi-color LCD display that communicates directly with the controller. When the onboard self-diagnostic system detects a malfunction, the display automatically shows a code beginning with “E-“ (e.g., E-06) in the multi-function display area. The number shown corresponds to the specific fault content detected by the system.

Power-On Self-Check #

When you power on the scooter, the display and controller perform an automatic self-check. If any component fails this check — such as the brake cut-off switches, throttle signal, or motor Hall sensors — the corresponding error code will appear immediately. You cannot ride the scooter until the fault is cleared.

C10E Single-Motor Architecture #

The C10E is a single-motor (rear-drive) model with one 500W motor. This means the scooter will only display error codes related to the rear drive system and system-level components. Codes E-01, E-03, and E-08 pertain to the rear motor and rear controller. Codes E-11 (front Hall fault), E-13 (front controller fault), and E-18 (front motor stall) are dual-motor-only codes and will not appear on the C10E.

Step-by-Step Diagnostic Workflow #

• Stop the scooter safely — step off the deck and engage the brake lever. Do not continue riding if a motor, brake, or controller error is displayed.


• Read the error code — note the exact code shown on the LCD multi-function area (e.g., E-06).


• Inspect cable connections — visually check the wiring harness near the steering stem and rear motor for loose plugs, bent pins, or water ingress.


• Check brake and throttle — ensure the brake levers return to their resting position freely and the throttle lever is not stuck.


• Restart the system — power off, wait 10 seconds, then power back on. If the error persists, refer to the complete error code table in Section 3.

3. Complete Error Codes & Diagnostic Solutions Table #

The table below lists all official error codes applicable to the Joyor C10E. Because the C10E is a single-motor model, only codes E-01 through E-09 are relevant. Dual-motor codes (E-11, E-13, E-18) are included for reference but will not appear on this model.

4. P-Settings Parameter Table & Factory Reset Guide #

The C10E operates on a 48V system, which means the P03 working voltage parameter must be set to 48. Below is the complete P-Settings reference table with factory defaults for the C10E 48V single-motor configuration.

C10E Factory P-Settings (48V Single-Motor) #

How to Access P-Settings on the C10E #

• Turn on the scooter by pressing and holding the Power button.


• Press and hold the “+” and “−” buttons simultaneously for approximately 3 seconds to enter the setup menu.


• Use the Power button to cycle between parameters (P02 → P03 → P04 → … → P99).


• Use the “+” and “−” buttons to adjust the value of the selected parameter.


• After adjustment, press and hold to return to the main interface and save changes.

Factory Reset via P99 #

If you experience unexplained electrical glitches or after replacing components such as the display or controller, restoring all parameters to factory defaults is highly recommended.

• Turn on the scooter and enter the P-Settings menu as described above.


• Navigate through the parameters until you reach P99.


• Press and hold the setting button for 5 seconds.


• The display will flash or reboot, confirming that all parameters have been restored to their factory defaults.

5. Official Warranty Terms & Battery Maintenance #

Warranty Coverage #

Joyor provides a limited warranty covering manufacturing defects in material or workmanship under normal installation, use, service, and maintenance. The warranty applies only to consumers purchasing from an authorized Joyor retailer or reseller and extends only to the original purchaser — it is non-transferable.

Warranty Exclusions (Not Covered) #

The warranty does not cover problems caused by:

• Commercial use, accidents, abuse, or neglect


• Shock, heat, or humidity beyond product specifications


• Improper installation, operation, maintenance, or any unauthorized modification contrary to the user manual


• Use of batteries or chargers from other manufacturers — any resulting damage is not covered


• Water damage from riding in rain, through water, near saltwater, or at the beach — rain and water damage are explicitly excluded from warranty coverage


• Riding after a collision, crash, or fall without prior inspection


• Products returned with removed, damaged, or tampered labels, or any unauthorized alterations


• Cost of international warranty shipping at any time

Battery Maintenance Essentials #

The C10E is equipped with a 48V 10.4Ah lithium polymer battery. The average battery lifespan is approximately 1,000 charge cycles, and under normal use and proper maintenance, it can generally exceed 1,000 cycles. Proper maintenance is essential for maximizing battery lifespan and preserving warranty coverage:

• First-time use: Fully charge the battery to 100% before riding for the first time.


• Avoid full depletion: Never let the battery fully discharge. Always maintain a minimum of 10% charge. For optimal performance, keep the battery above 50%.


• Charge promptly: Do not leave the scooter with a significantly discharged battery for several hours. Recharge immediately.


• Long-term storage: If the scooter will not be used for an extended period, ensure the battery is charged to at least 40–50%. Charge the scooter at least once every 30 days to prevent deep-discharge damage.


• Use original charger only: Always use the charger supplied by Joyor that matches the C10E model (C10 charger: 54.6V output, 100–240V input, 50/60 Hz). Using chargers from other manufacturers may cause malfunctions and will void your warranty.


• Charging indicator: Red light = charging in progress. Green light = charging complete. When the light turns green, unplug the charger from the power source first, then disconnect it from the scooter.


• Charging environment: Charge in a dry, well-ventilated area. Never charge in enclosed spaces, damp environments, or near flammable materials. If the charger becomes excessively hot, stop charging immediately.


• Supervised charging: Never leave the scooter charging overnight or without supervision. Polymer lithium batteries require extreme caution — inappropriate charging, damage, or overheating can result in fire. Do not use, charge, or leave a damaged battery unattended.


• Temperature limits: Do not store or charge the scooter in temperatures below 0°C or under direct sunlight. Keep the battery dry — negative environmental conditions can damage the battery.


• Keep charging port clean and dry: Always ensure the charging port cover is sealed before riding. Moisture in the port can cause short circuits.

Routine Maintenance Recommendations #

• Monthly: Check and tighten all screws, nuts, and bolts. Inspect tires for proper pressure, wear, and damage.


• Brakes: Regularly check brake pad thickness. If significant wear is present, replace promptly to prevent brake failure.


• Cleaning: Power off the scooter before cleaning. Wipe with a dry cloth only. Do not use alcohol or cleaning agents. Do not spray liquid directly on any component.


• Folding system: After extended use, check and tighten the folding mechanism screws using an Allen wrench to ensure they are secure.


• High-intensity use: For professional or frequent use, inspect screws monthly and consider replacement every 6 months.

Before Contacting Support — Prepare the Following #

To ensure a fast and efficient warranty or diagnostic service experience, please have the following information ready before contacting Joyor support:

• Proof of Purchase: Original order number or receipt verifying the purchase date and authorized retailer.
