Freelander 1 OBD2 - No communication with vehcile

So, as some of you will be aware, I've been having a lot of issues since acquiring our 2005 2.0 diesel TD4 just over a year ago. Basically, it keeps cutting out at random and despite trying A LOT of things we haven't managed to fix it (separate post here if you want to read the background - https://www.landyzone.co.uk/land-rover/td4-2-0-diesel-cut-out-no-start.323156/page-2#post-4151176)

Anyway in order to try and help us get to the bottom of this I bought a used Hawkeye diagnostic tool on eBay. It promptly arrived today and so I went straight out to test it and see what it would throw up. And that's where it ends I'm afraid, 2 steps back!

I kept getting a communication error and I couldn't get it to communicate with the Freelander. As a test I then connected an old generic OBD2 reader that has linked with this car in the past. Although it never brought up any codes it always 'communicated' OK. I got the same issue as this machine was also unable to link to the car.

Does anyone have any ideas where to start with this and why it may have suddenly stopped working (the only parts we've changed over are the ignition switch and the crank sensor?). Ideally we need to get this sorted so we can press on with cutting out issue.

Did the Hawkeye come with the correct cable/ adapter for the FL1?

Hi Nodge, yes it did. It was used by the previous owner on their Freelander 1 and as far as I know is set up for this vehicle?

There's only one cable for the hawkeye. There are some optional connectors depending on vehicle/use which change the pin wiring when fitted to the end of the cable. If the hawkeye is programmed for use with yer FL1 then "Freelander 1" will be listed int main menu when it's first powered when yer plug it into yer obdii socket. Are yer still having problems using the hawkeye or got it sorted?
