Jack, et al who have read OBD ABS codes w/ your Actron. Are you reading them on the D1 or the D2?
I'm trying to figure out if the problem is "reading" the codes, or "interpreting" what the codes are. Its my understanding right now that the SLABS codes aren't readable via a regular OBD 2 reader. This would indicate that a testbook is sending an escape sequence to switch from an OBD2 protocol to their proprietary protocol. If this is the case, I'll need to sniff that sequence in order to be able to pull ABS codes on a D2.
I also just got off the phone with a friend of mine who is a serial communications geek (embedded hardware/software engineer). He is willing to work with me to "sniff" the serial communications between a testbook and the OBD II port, so we can implement the same thing ourselves in our own free/low price software. The problem I have is getting access to a testbook or autologic unit with an experienced operator for a few hours. Anyone in the Pacific Northwest that can help?
