The PDU tests whether or not the antenna raises and lowers correctly. Although it is obvious if the antenna is not operating, the PDU analyses why it is not operating and indicates problems such as a faulty radio head signal output, faulty wiring, loss of power due to a blown fuse - two fuses in the fascia end fuse box left side and one in the luggage compartment fuse box.
