That is the ECU, the dial turns it to normal and diagnostic modes, and the green flashing light is an indicator. When you check your codes, that light and a red light will flash in sequence for the diagnostic codes. There's a how-to in the garage.

Yep, its the ECM. The lights are not just for displaying codes, when you are not in diagnostic mode, they are displaying the operation of your O2 sensor. when they flash back and fourth, thats good.
