Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, wrench).
Safety Warnings: Disconnect the negative battery terminal to prevent electrical shock before starting any work.

2. Disconnect the Battery

Using a wrench, disconnect the negative (-) battery cable first, followed by the positive (+) battery cable.
Remove the battery from the vehicle if necessary for better access.

3. Reset the Battery Management System

Reinstall the Battery: Reconnect the battery, starting with the positive (+) terminal followed by the negative (-) terminal.
Ignite the Ignition: Turn the ignition key to the "ON" position without starting the vehicle, allowing the BMS to initialize.
Use OBD-II Scanner: Connect the OBD-II scanner and navigate to the BMS reset function (if available) to perform the reset.
Follow Scanner Prompts: Follow the prompts on the scanner to complete the reset procedure.

4. Final Checks

Recheck Battery Voltage: After reset, measure the battery voltage again with the multimeter to ensure it reads correctly.
Start the Engine: Start the vehicle to confirm that the BMS reset was successful and that all systems are functioning properly.
