OBD Land Rover Specific

G'day,
I own a 2000 model Land Rover Discovery TD5. There is an OBD socket below the dash board.
I purchased an Elmscan 5 USB interface which only worked partially, the first 5 codes out of approx 100. The Elmscan would be a very useful device on OBD II compliant vehicles and the people are very helpful. They have agreed to refund my money ($129 US) upon the return of the device.
This leaves me with two problems:-
1. Can anyone describe a cable or interface that converts the signal levels in the OBD connector to RS232 or USB? I do not want a device like the ELMSCAN which interprets the codes, merely a voltage converter.
2. Is there software available (source in C preferable) that I can use to converse with the OBD processors via the connector?
Regards, Terry

Welcome, Terry.

I think this is what you're looking for. It might be cheaper to just go to the dealer though....

G'day,

Thank you for your suggestion. It may work on my Australian model but I am not certain. I have asked the supplier for confirmation.

The other problem is the price..... $2,000!!!

Why is this so expensive? I may be forced to go down the make it myself track.

I have kept the OBD II <-> RS2323 cable that came with the ELMSCAN 5 to carry oiut some preliminary experiments. Can you tell me the voltage levels that I can expect from the OBD II connector? Baud rates would help also.

Thanks, Terry

Try nanocom (should do all of DII) only costs about £200+ tax.
