Figured I'd start a new thread on this. In another thread here, it was posted that it is possible to read and clear error codes using a standard protocol OBD II reader found on Amazon or eq. I purchased a very cheap version (<$20), and along with a 6-pin adapter was able to connect, read and clear an error code on a V7-850 model. NO IT WILL NOT RESET THE SERVICE WRENCH OR RESET THE TPS unfortunately.
