taoybb Posted April 30, 2019 Report Share Posted April 30, 2019 Hello, is it possible to use CAN to read some data from OBD-II port?. My car is 2005 Toyota MPV running on Monsoon ECU (Sorry just borrowed ECU from a friend and mine own is on it way, so serial will come soon). I couldn't get wheel speed input to work properly and interesting in reading data from OBD-II port instead. The OEM OBD-II is ISO 9141-2 (5 baud init, 10.4 Kbaud) so is it possible?

Adamw Posted May 2, 2019 Report Share Posted May 2, 2019 We dont have OBD2 available as an input at this time. I dont think there are any plans to at this stage either. Not a bad idea though, it is not something I had considered before. I would expect your car to have CAN bus though. You might have to buy a cheap CAN sniffer and learn how to find it. Have a look at the original ecu and see if it has any wires that are twisted pair connected to it, if so that will likely be the CAN bus. I have a liitle bit of CAN info for a couple of late Toyota's and they both have wheels speeds on the same CAN ID's. Quote Link to comment Share on other sites More sharing options...
taoybb Posted May 3, 2019 Author Report Share Posted May 3, 2019 According from my car wiring diagram, there is another bus available is BEAN (Multiplex). I had read on AltezzaLink in help section but don't really get what " ECU contains a CAN to BEAN converter" mean. Is Monsoon support this as input?
