Cause

Error code 02E on an Okai scooter indicates that the battery voltage has fallen below a safe operating threshold (43V). This can happen due to:

• **Depleted battery:** The scooter has been used extensively without recharging.
• **Battery damage:** The battery may have internal damage or is nearing the end of its lifespan.
• **Faulty ECU sampling circuit:** The ECU's circuit responsible for monitoring battery voltage is malfunctioning.

Fix

1. **Charge the battery:** Connect the scooter to a suitable charger and allow the battery to charge fully. 2. **Check Battery Health:** After charging, if the error persists, consider the following:

   * **Battery Age:** If the battery is old, it may be nearing the end of its lifespan and needs replacement.
   * **Physical Inspection:**  Examine the battery for any signs of damage (bumps, cracks, leaks).

3. **Replace the ECU:** If the battery is in good condition and charging doesn't resolve the issue, the ECU may be faulty and needs to be replaced.
