To understand more
This specific error code indicates that the Bench access port has been intentionally or unintentionally locked by previous tuning software or security patches. When bFlash attempts to initiate communication, the Unexpected data response is the ECU's way of rejecting the unauthorized diagnostic request, necessitating a low-level hardware connection via BDM to regain control.
