My 2015 Freightliner M2 has an alarm going off and the park

Customer Question

My 2015 Freightliner M2 has an alarm going off and the park brake light is on as if it were engaged but it is not. Seems to stop as we stop the truck but then starts right back up as we go.
JA: We'll do all we can to help. Is there anything else important you think the Heavy Equipment Mechanic should know?
Customer: no
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Heavy Equipment Mechanic about your situation and then connect you two.

Good morning
Do you have air or hydraulic brakes?

It seems to think the e-brake/park brake is engaged but it isn't.

I'm asking my driver for more info as I know this is a non cdl truck and doesn't have air brakes. I answered hydraulic prematurely but is there other options for this vehicle?
Customer: replied 11 months ago.
Seems to make sense that they are hydraulic then and to my driver

The park brake
Is it a yellow button on the dash or a foot brake like on a car

foot brake like on a car

The sender for the light is down by that peddle. It has a little metal tab that breaks. And I think that's what you have going on. Let me know how you do
Customer: replied 11 months ago.
Thanks. I will check it out when the truck gets back.

I can see the switch/sensor and the little metal tab is still attached so that doesn't seem to be the issue. I got freightliner to send the schematic but everything seems to be in place?
Expert:  go-west.. replied 11 months ago.
Manually toggle the switch up and down with your finger
Does the light stay on?
