Subject: Re: 96 PCM to cluster communication question by merlot566jka on 2013/9/11 1:31:43 Yes, the tech 2 uses class 2. It also reads 8192 UART, 160 baud, and CAN. With different expansions, it can read almost any manufactures data. The rest of you are stuck with the old data, for now. But that old data (GM 8192 UART) is much easier read by a pc. Ie the interface is cheap an easy. Be happy about that. To clairify, GM 8192 UART has nothing to do with PC UART. It also has nothing to do with RS-232, which is just a style of connection. GM 8192 UART is proprietary to GM, and follows guideline writte by the SAE. Those guidelines are public, as is all of the communications protocol for all US vehicles. They are readily available on google. By law they have to be, which was the whole point to OBD2 to begin with. |
