Information 

If the Gateway  control unit is programmed, ensure a charging voltage of 14.0 - 14.2 V  at the Gateway control unit. Adjust the charger's voltage if necessary. When programming is complete, reset the charger's voltage.

Information 

Ensure the consistency of a combination of hardware and software versions 

After performing software updates, always make sure that the target software versions are also actually installed on the control units and that the system is therefore ensured.

This also applies in the case of hardware replacement.

See TI 9X00 Information on tie software system for various control units in the vehicle (112/21)
