Then got to the ground strap at the back of the head... And it was loose. I had already cleared the codes but the SES was still in. Started the car, tried to clear the codes, and the light was still on.

Drove it a mile, stopped and started it back up and the SES light is off.

Checked for codes, none.

Fingers are crossed.
