Synchronization Of The System Time

In order to ensure the same system time in all modules, a regular synchronization of all satellites is necessary.

There is a distinction between the synchronization in normal operation and synchronization of new modules installed in the vehicle as spare parts.

The mileage reading is also stored in the SIM. In order to set up a relation between the system time and mileage reading, the current mileage reading is saved during the synchronization of the system time.
