Re: About to use my Tech 1a for the first time, pointers? ---
You will plug the needed cartridge in before hooking it up top the car. The mass-storage cartridge is a more modern big memory chip style that contains many of the earlier cartridges in an all-in-one unit. I have not been able to communicate with my ABS unit with my bosch cartridge (maybe its bad), but he mass-storage pretty much works for everything else.
it will give you choices to enter if you want to read codes, erase codes, look at live sensor data, record while running, or a few other choices.
