Solution

To understand more

This error is a safety feature of the ECU. It performs a self-check before allowing programming, and if any pre-set requirement is not met (like improper voltage or poor connections), it will reject the request to protect its memory from corruption. Fulfilling these conditions ensures a stable environment for writing data.
