E10/E02 troubleshooting method
Step 1: Turn off the LCD and remove the battery.
Step 2: Controller Parts: Take out the controller and keep only the power supply cable, main wiring harness, motor cable, and blue, green, and yellow wires on the controller side. Disconnect the wires of the phone holder and booster, and it is better to mark them with stickers or tape to prevent incorrect insertion.
Step 3. Handlebar Part: First use tape or stickers to mark the plug to prevent incorrect plugging later. Only keep the connections of the thrumb throttle and LCD, and disconnect all other parts connections.
Complete the above 3 steps, install the battery, and turn on the LCD for power. E10/E02 may disappear or still exist. The following are the corresponding solutions:
- Situation 1 and Solution: Turn on the power, if the E10/E02 disappears and returns to normal, it means that the E10/E02 is caused by the booster, or phone holder, or brake cable, or headlight, or horn/hedlight switch, or headlight. Try these accessories in turn and plug them in to check which accessory causes E10/E02, then we will send you corresponding part for replacement.
- Situation 2 and Solution: Turn on the power, if the E10/E02 is still there, we will send the main wiring harness, controller, and motor cable for your replacement.
