No no need to remove the battery terminal or any speed sensor. I had already described it is bleed like a conventional system. So no need to reverse bleed it.
The procedure is as follow which we are practising regularly.
Starts from rear left wheel and then rear right then front left and front right wheel.
Remember to replace the brake fluid with a new one never use the old bleeded out brake fluid. Of the fluid is dirty or discoloured then keep bleeding from individual wheel until you see the clear fluid running from that specific wheel.
