Unfortunately, i do not know the models as they were doing all the work very quickly.
One scanner was wired with a large screen.. And the other two scanners were pluggable into the car's scanning port. After doing so; they tried connecting it wirelessly on a handheld tablet.
I am in Peshawar and went through 3 highly reputable workshops but returned with no success.
The workshops even replaced the ecu of my car assuming that may be my car's ecu had an issue but no luck in getting it connected with the computer scanner either
