Thank you so much for your kind effort on this issue. Today, I could resolve this issue by using waveform analyzer.
Conclusion : User's manual that Xhorse provide should be modified ....
1. In case of VOLVO S80 1999 2. Waveform between ignition switch and key : when Key is put in ignition switch and turn on No.2 position again within 2 min. waveform is exactly same waveform on each turn on timing. 3. However When Key is put in ignition switch and turn on No.2 position again more than 2 min, then wave form become different on each timing. 4. So, to turn off VDDI MINI key tool is "not" necessary. and also to turn off blue tooth of smartphone is "not" necessary too. 5. So, as user's manual , in case of VOLVO , you need to have interval to collect data more than 2 min between each data collection steps. You don't need to turn off VDDI MINI key tool and blue tooth of smart phone.
PS : within 2 min , 2 or 3 small relay sound are observed from dashboard of VOLVO. According to analyze Those small relay sound looks like a reset timing of communication between ignition switch and key.
