Announcement Of Terminal 15w "Wake-up"

The CAS and the ZGM (Central Gateway Module) are the only control units that can wake up the vehicle electrical system.

The control units on the K-CAN S, K-CAN P, byteflight and MOST are awakened by the network management (NWM) on the respective bus.

The control units on the PT-CAN are woken up via a high signal on the activation wire for terminal 15 wake-up. If a PT-CAN control unit receives the change in voltage "low-high" at the wake-up input, the control unit begins with reception and the evaluation of the messages from the PT-CAN.

Two modules (ZGM and the Power Module receive KL 15 wake-up as a hardwired input from the CAS in addition to the network management wake-up signal over the bus.
