This function is used when a new battery has been installed in the vehicle. If registration of battery replacement does not take place the vehicle's power control will not work correctly. This may lead to malfunctions such as, e.g., reduction or deactivation of individual consumers in the vehicle.
Primarily, a battery with the same battery capacity should be installed in the vehicle. If a battery with higher or lower battery capacity or an AGM-battery is installed, the vehicle's coding data must be changed.
