Q1: Can i use SSM4 (Subaru Select Monitor IV) software with VXDIAG Multi Tool for Subaru?
A2: Yes, use software 2020.07 and above. It is compatible with VXDIAG Subaru VCX PLUS . Older software is not compatible with SSM4.
Q2: I try to install VXDIAG Subaru SSM3 software, it gave me an error “Com. with All systems Failed”. Interface was connected and the device indicator turned red. The I saw there is a SSM4 software folder, then installed SSM4, it told me to change computer date otherwise the SSM4 license will be invalid soon.
To install VXDIAG Subaru SSM III software, you need to install the patch as well.
Don’t not run SSM4 software. Run SSM-3 software.
Q3: I bought the VXDIAG SSM III with 2017.10 software. Can I use the old patch with the new V2018.04 SSM3?
A3: Better use the new patch with 2018.2V software.
