	Check
1	Check whether vehicle is affected by measure.	Affected vehicles: Perform SCN coding in SAM control unit (code: VS2FARIANZ) 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.	SM54.21-S-0230-01AAA
	Perform SCN coding
2	Install the 12 V charger.
		A sufficient power supply for the on-board electrical system battery must be guaranteed throughout the entire work procedure. Otherwise any undervoltage that occurs may damage the control units. Follow the operating instructions for the 12 V charger. Use the 12 V charger to ensure an adequate voltage (min. 12.5 V) for the on-board electrical system battery.	AR54.10-S-1127E
3	Install vehicle diagnosis system.	If diagnostic system is not yet attached.

	Service Information: Regio DVD and Retail Data Storage	Always use the latest XENTRY Diagnosis software. It is absolutely essential to precisely follow the operation steps as described in the vehicle diagnosis system. If diagnostic system is already connected to vehicle, ↓ continue with operation step 4.	SI00.01-D-0044SG
4	Perform SCN coding on signal acquisition and actuation module (SAM) control unit (N10/1).
		To do this, select the following menu items: Control units view → N10/1 - Signal acquisition and actuation module (SAM) → Adaptations → Control units update → Updating of SCN coding Follow instructions in XENTRY. You are automatically guided through the SCN coding procedure. After successful SCN coding, the following is shown: Documentation for repair order. The SCN coding sequence has been completed successfully.	AR54.21-S-0015E
5	Remove vehicle diagnosis system from vehicle.
6	Remove the 12 V charger from vehicle.
