Packaged up into bytes, multi-command data is sent internally to various vehicle modules. They can also be sent remotely to central fleet operations over mobile data networks. Multi commands are split into outgoing commands and incoming states.
A request from an end user who is monitoring a vehicle remotely is sent to the vehicle. The user may be requesting a lot of information at once and the vehicle needs to process it once it has been received. These multi commands are received by the vehicle, processed, and returned to the end user in real-time thanks to onboard CPUs and telematics devices.
