first thanks for replay me.
in the obd 2 you have can h can l , k line etc.
sorry but what do you mean.....i dont understand "can h can l, k line"
There is no way you are going to sort out the protacol on your own.
I used google to search information but I could not find anything that could help clear, i see more ODB scanner, software, cable & connector......thanks for more information
