Xhorse VVDI MB Tool can support renew ISM/Gearbox, you need read the ecu firstly, if read failed, it will not support.
But we received feedback than read ISM OK, and get erase password OK, renew shows : Erase target unit success. But after renew OK, read the ISM again, it gets “Read fail Position01 error”
Engineer replied:
If this status, it means not support either.
