1. Quick Diagnostic Process: Reading the S10-SZ LCD Display #
The S10-SZ is equipped with a multi-color LCD display that communicates directly with both the front and rear controllers. When the onboard self-diagnostic system detects a malfunction, the display automatically switches to the error interface and shows a code beginning with “E-“ (e.g., E-06, E-11) in the multi-function display area.
Power-On Self-Check Sequence #
When you power on the scooter, the display and controllers 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.
Understanding Front vs. Rear Drive Errors #
Because the S10-SZ is a dual-motor model, error codes are split between rear-drive faults and front-drive faults. Recognizing which motor system is affected is the first and most critical step in diagnosis:
| Error Category | Codes | Affected System |
|---|---|---|
| Rear-drive faults | E-01, E-03, E-08 | Rear motor / rear controller |
| Front-drive faults (dual-motor only) | E-11, E-13, E-18 | Front motor / front controller |
| System-level faults | E-02, E-04, E-05, E-06, E-07, E-09 | Throttle, brakes, battery, communication, temperature |
Step-by-Step Diagnostic Workflow #
- Stop the scooter safely — step off the deck and engage both brake levers. 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).
- Identify front vs. rear — determine whether the fault is isolated to the front drive (E-11/E-13/E-18), rear drive (E-01/E-03/E-08), or is a system-level issue.
- Inspect cable connections — visually check the wiring harness near the steering stem, front wheel, and rear motor for loose plugs, bent pins, or water ingress.
- 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 2.
âš Safety Notice: Do not attempt to ride the S10-SZ if it displays any error related to the brakes (E-04), throttle (E-02), or either controller (E-03/E-13). Push the scooter manually to a safe location before performing diagnostics.
2. Complete Error Codes & Diagnostic Solutions Table #
The table below lists all 12 official error codes for the Joyor S10-SZ, covering both universal codes (E-01 to E-09) shared across all S-Z Series models and dual-motor-exclusive codes (E-11, E-13, E-18) that apply only to dual-drive models like the S10-SZ.
| Code | Description | Affected System | Troubleshooting & Solution |
|---|---|---|---|
| E-01 | Rear Hall fault | Rear motor | Hall sensor failure or loose wiring in the rear motor. Inspect the rear motor cable connector for water ingress, bent pins, or disconnection. If the connection is intact, the internal Hall sensors may require professional replacement. |
| E-02 | Throttle fault | Throttle assembly | The accelerator throttle is sending an abnormal signal. Power off, ensure the throttle lever returns to its resting position, then restart. If unresolved, inspect the throttle cable under the handlebar cover for loose connectors. The throttle assembly may need replacement. |
| E-03 | Rear controller fault | Rear controller | Internal fault detected in the rear drive controller. Allow the controller to cool for 30 minutes in a ventilated area. If the error persists after restart, the rear controller requires professional diagnosis — do not open the controller housing yourself. |
| E-04 | Brake fault | Brake system | Triggered during instrument or controller self-check alarm. Check if either brake lever is physically stuck or if the brake cut-off switches are jammed. Free any obstructions and ensure both levers return to their resting position freely. |
| E-05 | Controller undervoltage protection | Battery / Controller | The 60V battery voltage has dropped below the safe threshold. Fully charge the battery using the original Joyor charger. If the error appears on a fully charged battery, the battery cells or BMS may be degraded — contact support. |
| E-06 | Communication fault (Display not receiving data from Controller) | Display ↔ Controller | Wiring fault between the LCD display and the main controller. Trace the communication harness from the display down the steering column. Check for disconnected plugs, bent pins, or moisture. Reconnect firmly and ensure the folding mechanism is not pinching the cable. |
| E-07 | Communication fault (Controller not receiving data from Display) | Controller ↔ Display | Reverse communication failure. Verify that the display is properly seated and the main cable is not damaged. If the display works on another scooter, the controller’s communication board may be faulty. |
| E-08 | Motor stall protection (rear) | Rear motor | The rear motor is physically blocked or overloaded. Lift the rear wheel and check for debris, foreign objects, or brake pad interference. Clear any obstruction and manually spin the wheel to confirm free rotation before restarting. |
| E-09 | Temperature protection | Controller / Motor | The controller or motor is overheating. Stop riding immediately and park in a cool, shaded area. Allow at least 30 minutes for cooling. Avoid riding in extreme heat or on steep inclines for prolonged periods. Do not operate the scooter below −5°C. |
| E-11 | Front Hall fault | Front motor (dual-motor only) | Sensor failure in the front motor. Inspect the front motor cable routing and connector pins for damage or water ingress. If all external connections are secure, the front motor Hall sensors need professional inspection and possible replacement. |
| E-13 | Front controller fault | Front controller (dual-motor only) | Fault detected in the front drive controller. Check all connections leading to the front controller box. Do not attempt to open the controller housing. If a system restart does not clear the error, the front controller requires professional repair or replacement. |
| E-18 | Motor stall protection (front) | Front motor (dual-motor only) | The front motor is physically obstructed. Lift the front wheel and check for debris or brake drag. Ensure the tire spins freely. Clear any obstruction and restart the system. |
📌 Note on Dual-Drive Codes: Error codes E-11, E-13, and E-18 appear only on dual-motor models such as the S10-SZ. If you see these codes, the issue is isolated to the front drive system and the rear motor may continue to function independently. However, we strongly recommend resolving the fault before resuming operation.
3. 60V System P-Settings Parameter Table & Reset Guide #
The S10-SZ operates on a 60V system, which means the P03 working voltage parameter must be set to 60. Below is the complete P-Settings reference table with factory defaults for the S10-SZ 60V dual-motor configuration.
S10-SZ Factory P-Settings (60V Dual-Motor) #

- Use the up/down buttons to adjust the value, then press Mode again to confirm and save.
Single / Dual Drive Switching #
The S10-SZ supports single-drive and dual-drive mode switching (controller support required). Short press the designated key to toggle between single-drive mode (for extended range and energy efficiency) and Dual-Drv dual-drive mode (for maximum power and hill-climbing capability).
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 Mode/Menu button for 5 seconds.
- The display will flash or reboot, confirming that all parameters have been restored to their factory defaults.
âš CRITICAL — Post-Reset Verification: After performing a P99 factory reset, you must manually check and confirm that P03 is still set to 60 for the S10-SZ’s 60V system. An incorrect voltage setting (e.g., defaulting back to 48V) can cause erratic performance, false error codes (such as E-05 undervoltage), or damage to the controller and motor system.
