Question:
Does VXDIAG VCX NANO GM scanner support 2017 Roewe ERX5 new energy vehicle?
No, GM license does not do Roewe diagnosis.
You will need a VDI interface.
VDS2/VDS3/GRADE-X is a diagnostic software for Chinese SAIC group brands Roewe, MG, Wuling, Baojun, Maxus, Datong etc.
Or use universal diagnostic scanner Launch X431, Autel or thinkdiag etc.
