It is actually really hard for a new FL1 owner to figure out what diagnostics systems will work with the FL1. Information is scattered across the net and nobody seems to give a clear answer.
By far the cheapest option is a a knockoff delphi ds150 interface from China with dodgy software installed on an old laptop. These range from £25 to £65, the more money you spend, the better the interface you get.
Once setup this will provide full diagnostic access to all of the freelander's systems.
Things that don't work include: ELM327 style dongles, JLR mongoose (ISS/SDD), VAG-COM etc.
It has taken me many years but I have finally come to understand why you cannot see anything useful using a standard ELM327 style dongle. It would seem older LR vehicles used a kind of security authentication for diagnostics access. Beyond that it is just boring old K-Line one wire like everything else. Below is a link to the code for calculating the security response for the TD5 engine. I suspect the FR1 uses exactly the same mechanism but since getting a knockoff delphi I am less inclined to figure it out.
