This type of concern is usually caused by a bad parking brake sensor. This is a pneumatic switch on the inside of the firewall. On the cab pass thru panel on the drivers side, the switch is clearly marked by “PBS”. I would replace this switch and that should remedy your issue. Thank you

I'm not sure where you are talking about?
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 7 months ago
The cab pass thru panel is where all the wiring and air lines pass thru the cab on the drivers side. If you remove the lower kick panel where the diag plug is you will see the panel and sensor right behind it
