A method for engaging a pneumatic parking brake 30 of a parking brake system 12 of a motor vehicle 10, wherein a first controller 14 of the parking brake system 12 receives a parking brake command 18 (e.g. from an autonomous driving system 20) and attempts to engage the pneumatic parking brake 30 via a first mode 36. The first controller 14 transmits a parking brake status 24 to a second controller 26, which is a separate component from the parking brake system. If the parking brake status signal indicates a failure in the engagement of the pneumatic parking brake 30 via the first mode 36, the second controller 26 engages the pneumatic parking brake 30 via a second mode (38; fig. 2). The second mode may involve repeatedly engaging the service brakes to deplete pressure from the pneumatic parking brake or actuating a valve of the parking brake system.
