Turn the screw back to it’s original position, and your ECU should now be in the diagnostic mode II.
From the first mode you will want to enter Mode II, to achieve this you must turn the mode selector screw fully CLOCKWISE, and hold it there for 4 seconds. To begin your ECU diagnostic procedure you must turn the ignition key to the “ON” position, which will put your Nissan ECU into Mode 1.
