I have been an auto mechanic for about 10 years. I always wished I could use my laptop to be used as a scanner. Why could it not be? It makes sense. Because PC is much more sophisticate than a conventional scanner. All it needs is an adapter that connects between PC and DTC (Data Link Connector) and a software.
Now, these are on the market. Small adapters or cables translate vehicle’s info through OBD2 port to your laptop, smart phone, or tablet. Here is the site introduces you all software and products. I share my knowledge about these devices and software and want you to get information you need.
