	Check
1	Check whether vehicle is affected by measure	Affected vehicles: Perform SCN coding of headlamp control unit For authorized Mercedes-Benz service partners, only the entry in the Extended VEGA Application (EVA) edition, 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.	SM82.10-S-0019-01AAA
	Perform SCN coding
2	Connect diagnostic unit	The operation steps must be performed exactly as per Xentry Diagnostics. If Xentry Diagnostics is already connected to the vehicle: ↓ continue with operation step 3.
3	Connect battery charger
	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. Use the charger to ensure that an adequate power supply (min. 12.5 V) is provided for the on-board electrical system battery.
