      • Disconnect the affected module from the battery pack.
      • Replace it with a new module from a reputable supplier, ensuring compatibility.
      • Reconnect all wiring securely.

  4. Reassemble and Test:

    • Reassemble the battery housing and any components removed during the process.
    • Reconnect the 12V battery and clear any codes.
    • Test the vehicle to ensure proper operation.

Step 3: Battery Conditioning (if performance issues persist)
