	Check
1	Check whether vehicle is affected by measure	Affected vehicles: Perform SCN coding on instrument cluster control unit	SM54.30-S-0020-01AAA
	Perform SCN coding
2	Connect diagnostic equipment
	Connect STAR DIAGNOSIS and read out fault memory	Use XENTRY Diagnostics Version 07/2014 with all relevant and updated add-ons or a higher XENTRY Diagnostics version. 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.	AD00.00-S-2000-04E
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.
