Reading and Writing of Data
The SVT-current, SVT-nominal, vehicle order, vehicle profile and the I-levels can be read out from the VCM via diagnosis. These data are written in the VCM during vehicle programming and coding. SVT nominal, FA, FP and I-levels can be written independently of each other.
For data security reasons, signatures are used in the data exchange between the diagnosis or programming systems and the VCM.
