Default Service park assist 20mph

So, I replaced the two bad sensors on the park assist, and the unit works. My issue is that at around 20mph, the "service park assist" comes on the DIC. I noticed the light is still on when in drive, so I'm wondering if it might be the switch. All of the sensors tick when checked with the stethoscope. I thought at first it was a loose wire, but the issue is for sure speed related. When I press the switch (light on in drive going down the road) the light flashes and then stays on.

Any thoughts?
