Abstract
Various embodiments of a system and method of controlling an electronic parking brake system for an air braked vehicle are disclosed. A dash switch module receives a signal indicative of a parking brake request. The dash switch module transmits a parking brake control message using a first communication path in response to the parking brake request. A braking system controller transmits a check message in response to the parking brake control message using a second communication path. The dash switch module transmits a confirmation message using the second communication path in response to the confirmation message. The brake system controller transmits a control signal to the park control module to park or un-park the vehicle in response to the confirmation message.
