No crank, code P180C

When I turn the Ignition on, the dashboard will come On but when I crank the whole light will go off and accessory relay will be clicking as you attempt to crank, I have check power to terminal 87 and there is B+ voltage and check ground terminal 85 and there was ground. Checked the control side of the relay by connecting test lamp to terminal 86 and 85 and turn ignition on and the light illuminates. What could be the problem is it the ECM? Attached the picture of scan report.

Holy cow. That is amazing. Great job if not only figuring that out but providing that update so that we understood what happened.

Thanks for using 2CarPros.
