A:For example if car is some further from workshop and you must spent time driving to the car or customer is just TOO far to drive, so then he can sent EIS or drive by himself bringing EIS it with him at workshop. It's time saver and what if tool will not work via OBD? You will loose many time driving ex. 30 miles x2. If you have on bench, you can work at your place without risk of wasting time. Also calculating psw at the place of car might last 30 minutes, 1 hour in all keys lost? It's much time to sit in the car + you have to take care of battery charger. If you have on bench, you can drink a coffee or a beer if you want and enjoy the waiting time. Still no tool which can do all merc by OBD anyway.

A:CGDI can show mileage from EZS, new software come out, updated.

A:When using OBD, need disconnect ESL connector and look for K line pin to connect Yellow clip. When using on bench: look for EZS-ELV wiring and plug the clip to kline pin
