Using OBD2 Scan tool cable and adapter

I have an Innova CanOBD 2&1 Tool Kit. Can I use a "female 25 pin to USB adapter" to connect the cable in the kit to my PC? I have downloaded FORSCAN software to my PC and would like to disable the "Tire Pressure Sensor"

The Innova tool is specific to Innova to include the hardware/software.

The ForScan software is similar to what the Ford Company would use but it's free, it also needs a special adapter to work with the software and connect to the vehicle computer. These adapters will state ForScan modified or compatible since not all adapters will work with ForScan.

You can check the following link to get a better understanding on the Adapters.

Yes, that is a very good summary which I had already read, and now reread. The OBD Kit cable and 25 pin connector should provide a connection for all of the pins. If it would not work, would be because the response time and / or baud rate are not adjustable? Does the switch on some adapters control which pins are active, or the time / rate, or both? I am just trying to understand why the cable would not work. Do the referenced adapters contain software?

Unfortunately ForScan is engineered for the Adapters mentioned and of course you need drivers to interpret the data that's passed from PC to OBD, not the 25pin connector. The switch deals with the 2 different networks on the OBD CAN (HS/MS) within the vehicle computer. The ForScan is the Software that will interpret the data and convert it to your understanding and functions.

However, if you're a software engineer then you might be able to make it work with an understanding on the OBD Protocols. I have a decent understanding but I would not consider myself a SME.
