Activating/Deactivating The Parking Brake When Moving

It is possible to activate the parking brake while moving, that is to say at speeds exceeding 3 km/h. But this is an emergency function which must only be used when the normal brakes are not functioning.

A condition is that switch parking brake (3/272) is activated during the whole sequence. The ABS-function is used to obtain safe braking.

A sound signal is heard when the parking brake is activated when driving.

When activating the parking brake when moving the Park Brake Module (PBM) (4/115) will transmit a request, to the brake control module (BCM) (4/16) via the CAN network, to brake the vehicle using the ABS function. When the speed is less than 3 km/h the park brake module (PBM) will take over the braking by activating the electric motor in the brake calipers (6/146-147).
