Diagnostic Port

[murcod]

Jules, did you ever get the Scangauge working? I'm still hunting for a compatible option for connecting via the OBDII port but don't want to end up with another useless device that won't connect.

Some more info- I ended up purchasing one of those Ebay cheap ELM 327 V1.2A interfaces for use with a laptop.

Once again, it won't connect to my XL-7. It works fine on the wife's Mazda 6 and has some functionality on a Renaultsport Clio (- but hasn't picked up a logged coolant sensor fault I know about.)

I've continued "head butting the brick wall" and have all but given up now:

Hi David,



Unfortunately your Suzuki is not OBDII compliant. The important lines in your log file are listed below.



31 0100 55:22.251

32 SENT READ PIDS_0x20 55:22.251

33 SEARCHING... - OBDParse 55:25.566

34 NO DATA - OBDParse 55:25.566

35 SECS HAVE ELAPSED 55:36.251



Line 31, is where OBD 2007 sends the command 0100. At that point the Elm chip starts searching for the correct protocol for your vehicle . However on line 34, the Elm chip reports NO DATA from that command. Note it searched for approximately 2.5 secs. The rest of the log file can be ignored as OBD 2007 automatically resets and tries again with the same result.



On a successful connection, the log file would have shown a response on line 34, by listing the supported pids of your vehicle. It would have looked something like the following.



31 0100 23:35.093

32 SENT READ PIDS_0x20 23:35.093

All OBDII software should work in a similar way, therefore there is no point trying different software packages because they will all fail to connect if they are trying to connect to a non OBDII compliant vehicle. The US versions of the vehicle will be OBDII compliant, because all vehicles in the US have been compliant since 1996.



If you have any further questions, please do not hesitate to contact me again. To see OBD 2007 in action, you will have to connect to an OBDII compliant vehicle.

Graham

That's info from the guys at OBD 2007 who are an Aussie based company. I tried their demo software with no luck.
