	Notes on SCN coding of control units		AH54.21-P-0004-01X
	Check
1	Check whether vehicle is affected by measure.	For authorized Mercedes-Benz service partners, only the entry in the "Extended VEGA Application" (EVA) system, in the "Current" tab, is decisive. An additional test of the affected vehicles in the workshop information system (WIS) or vehicle list is thereby not necessary.

3	Connect charging equipment.
	Maintaining on-board electrical system voltage when performing test and diagnosis work on vehicle	During the entire work procedure a sufficiently large voltage supply must be provided for the vehicle's on-board electrical system. Otherwise any undervoltage that occurs may damage the control units. Follow the operating instructions for the charger. Use the charger to ensure that an adequate power supply (min. 12.5 V) is provided for the on-board electrical system battery.	AR54.10-D-1127TS
4	Update SCN coding of powertrain control unit (Common Powertrain Controller (CPC)).	The maintenance interval is increased in the powertrain control unit from 30,000 km to 40,000 km. The maintenance interval is recoded from code JI5 (Maintenance interval starting distance 30,000 km) to code JI6 (Maintenance interval starting distance 40,000 km) in the powertrain control unit. It is absolutely essential to precisely follow the operation steps as described in the vehicle diagnosis system.
5	Disconnect diagnostic system.
