Welcome to the Joyor Official Technical Hub. This guide is dedicated to the Joyor S10-SZ (also officially known as S10S-Z) — the flagship dual-motor electric scooter powered by a 60V system with a rated 1000W dual-motor output (2x500W) reaching up to 2000W peak power (2x1000W Peak). Whether you are dealing with an LCD display error code, adjusting P-Settings for your 60V configuration, or preparing for a warranty service request, this document provides the official diagnostic framework, parameter tables, and maintenance protocols to keep your dual-drive scooter performing at its best.
1. Quick Diagnostic Process: Reading the S10-SZ LCD Display #
The Joyor S10-SZ (S10S-Z) is equipped with an LCD display that communicates directly with both the front and rear controllers. When a malfunction is detected by the self-diagnostic system, the display automatically switches to an error interface and shows a code beginning with “E” (e.g., E-01). Because the S10-SZ is a high-performance dual-motor model, error codes are split between front-drive faults and rear-drive faults.
Follow this quick diagnostic workflow when an error appears:
- Stop Safely: Step off the deck and engage both brake levers to come to a complete stop. Do not continue riding if a motor, brake, or controller error is displayed.
- Read the Error Code: Note the exact code shown on the multi-function area of the LCD (e.g., E-06, E-11, E-13).
- Identify Front vs. Rear: Codes E-01, E-03, and E-08 relate to the rear motor/controller. Codes E-11, E-13, and E-18 relate to the front motor/controller. Codes E-04 through E-07 and E-09 are system-level faults.
- Check Cable Connections: Visually inspect the wiring harness near the steering stem and both front and rear motor connections. Look for loose plugs, bent pins, or water ingress.
- Restart the System: Power off the scooter, wait 10 seconds, then power it back on. If the error persists, proceed to the detailed error code table below.
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 and perform diagnostics before resuming operation.
2. Complete Error Codes & Diagnostic Solutions Table #
The table below lists all official error codes for the Joyor S10-SZ / S10S-Z, including both universal codes shared across Joyor S Series models and dual-motor-specific codes (E-11, E-13, E-18) that apply exclusively to dual-drive models.
| Code | Description | Affected System | Troubleshooting & Solution |
|---|---|---|---|
| E-01 | Rear Hall fault | Rear motor | Indicates a rear motor Hall sensor failure or loose wiring. Inspect the rear motor cable connector for water ingress, bent pins, or disconnection. |
| E-02 | Throttle fault | Throttle assembly | The accelerator throttle is sending an abnormal signal. Power off the scooter, ensure the throttle lever returns to zero position, then restart. |
| E-03 | Rear controller fault | Rear controller | Internal fault detected in the rear drive controller. Allow the controller to cool for 30 minutes. If persistent, contact official support. |
| E-04 | Brake fault | Brake system | Triggered during self-check. Check if either brake lever is physically stuck or if the brake cut-off switches are jammed. |
| E-05 | Controller undervoltage protection | Battery / Controller | The 60V battery voltage has dropped below the threshold. Fully charge the battery using the official Joyor 60V charger. |
| E-06 | Communication fault (Display ➔ Controller) | Display ↔ Controller | Wiring fault between the LCD display and main controller. Inspect the main harness down the stem for disconnections or moisture. |
| E-07 | Communication fault (Controller ➔ Display) | Controller ↔ Display | Reverse communication failure. Verify that the display is properly seated and main wiring is not damaged. |
| E-08 | Motor stall protection (rear) | Rear motor | The rear motor is physically blocked. Lift the wheel and check for foreign objects or brake interference. Clear and manually spin wheel before restart. |
| E-09 | Temperature protection | Controller / Motor | Overheating detected. Stop riding immediately, park in a shaded area, and allow 30 minutes for cooling. |
| E-11 | Front Hall fault | Front motor (Dual-motor) | Sensor failure in front motor. Inspect front motor cable routing and waterproof quick connector near the front hub. |
| E-13 | Front controller fault | Front controller (Dual-motor) | Fault in the front sub-controller. Check dual-drive switch wiring and sub-controller connections inside deck. |
| E-18 | Motor stall protection (front) | Front motor (Dual-motor) | Front wheel physically obstructed. Lift front assembly, check brake rotor clearance, and spin wheel freely by hand. |
Note on Dual-Drive Codes: Error codes E-11, E-13, and E-18 appear exclusively on dual-motor models such as the Joyor S10-SZ (S10S-Z). If you see these codes, the issue is isolated to the front drive system.
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 official reference table with default factory configurations:
| Parameter | S10-SZ Default | Description |
|---|---|---|
| P02 | 0 / 1 | Speed unit selection: (0) km/h, (1) mph |
| P03 | 60 | System rated voltage (Must be configured to 60V for S10-SZ) |
| P04 | 5 | Automatic sleep timer: 0 (off), 1–60 minutes |
| P09 | 1 | Start mode: (0) Zero start / Instant; (1) Kick-start safety mode |
| P12 | 5 | Start torque level: 1 (softest) to 5 (maximum dual-motor torque up to 2x1000W peak) |
| P15 | 100 | Maximum power speed limit percentage (1%–100%) |
| P99 | — | One-key factory restore: hold Mode button for 5 seconds in setting menu |
Critical Notice: After performing a factory reset via P99, always ensure P03 is set to 60. An incorrect voltage selection will cause false undervoltage errors (E-05) and erratic power readout.

5. Frequently Asked Questions (FAQ) #
Q1: How do I switch between Single Motor and Dual Motor mode on the S10-SZ? #
The Joyor S10-SZ (S10S-Z) features a dedicated red/yellow toggle button located on the left handlebar assembly. Pressing the button engages or disengages the front 500W motor, allowing you to seamlessly switch between single-rear-drive (for energy saving and cruising) and dual-drive mode (for maximum 2000W peak acceleration and climbing torque).
Q2: Why is my display throwing an E-05 error even though the battery indicator shows full? #
An E-05 code indicates controller undervoltage protection. If your battery is fully charged, this usually happens because the P03 parameter in the setting menu was accidentally changed from 60V to a lower voltage (like 48V or 52V). Access the P-Settings and verify that P03 is set strictly to 60.
Q3: How do I switch the speed unit from km/h to mph? #
Power on the display, press and hold the Power and Mode buttons simultaneously for 3 seconds to enter the P-Setting menu. Toggle to P02 using the Power button, change the value from 0 (km/h) to 1 (mph) using the Mode button, and hold both buttons again to save and exit.
Q4: How can I reset all P-Settings back to factory defaults? #
Enter the P-Setting menu by holding the Power and Mode buttons together. Navigate to parameter P99, then press and hold the Mode button for 5 seconds until the screen flashes. After a factory reset, double-check that P03 is set back to 60 for the 60V power architecture.
Q5: What should I do if my S10-SZ shows dual-drive error codes E-11 or E-13? #
Codes E-11 (Front Hall fault) and E-13 (Front controller fault) are specific to the front motor drive system. Power off the scooter and inspect the quick-connect waterproof cable leading down to the front wheel hub. Ensure the connector is tightly plugged in and no moisture or bent pins are present. If the issue persists, contact technical support for a replacement front controller or Hall sensor cable.
