Programming of Control Units
Please note that the state of charge (SOC) of the high-voltage battery must be checked before every control
unit programming procedure. The SOC value must be read from the instrument cluster or COMAND (under
hybrid functions).
If the SOC shows a value< 50 % , the high-voltage battery must be recharged (charging when stationary).
Follow the instruction in Charge High-Voltage Battery document AR54.1 O-P-1170EH (operation step 5.1 ).
The high-voltage battery must be charged to a state of charge of 75 % SOC before a control unit is
programmed with Xentry Diagnostics. If the SOC is between 5 % and 10 %, the HV contactors of the highvoltage battery must be closed manually.
Please note that there are two different procedures depending on which XENTRY DAS version is used. Jn
both cases, a password must be requested from the SDS HelpDesk.

high-voltage battery must be charged to a state of charge of 75 % SOC analogous to the document AR54.1 OP-1170EH operation step 5.1.
Valid for XENTRY DAS Version 11/2013
The high-voltage battery must be charged to a state of charge of 75 % SOC analogous to Charge HighVoltage Battery AR54.10-P-1170EH operation steps 4 and 5.1.
