Hawkeye Question

Hi there, I'm completely new to the Landy world and just bought a 1999 Disco 2 TD5.

Within a few days I started getting the three Amigos (which didnt surprise me after reading a lot of posts here) so that gave me the excuse to buy a Hawkeye to diagnose my problem.

When I plug the Hawkeye in and try to use any of the functions, it hangs with the following message:

Performing Test
Please wait...

When I try the Vehicle Comms Test I get the following error:

VEHICLE COMMS FAIL
K1 K2 K3

So I assumed that there is a problem with the Hawkeye communicating with the ECU. However, when I try the Hawkeye Self Test I get the following error:

Selftest Complete
Unit FAIL

So is there a problem with my Hawkeye or is it the link to the ECU or both? I've not managed to get it working yet.

I've emailed omitec so I'll see what they say. In the meantime, I checked the ECU and have found oil in the red connector (I've read the posts here and found this to be quite common). I've tried to clean all that out with wd40 and compressed air.

I'm guessing that I may need a new wiring loom and possibly ECU before I even find out what caused the three Amigo's. Just wondering what your thoughts are.

Its just a bit frustrating to buy the Hawkeye and not be able to use it to diagnose my problem lol.

Cheers,
Pete

p.s. If anyone is in the Stamford area, you are welcome to use my Hawkeye.

have you received the unlock code from omnitech prior to using the hawkeye

Yea, I've input the code

Sounds like you may have a duff hawkeye, can you plug it in another TD 5 Disco and prove it
Your dash lights will be an ABS sensor very often front nearside. Do prove this first

There are another three ABS wheel speed sensors on a Disco. If your 3 Amigos is due to an ABS sensor it would probably be on of the front ones first. There are other reasons for the 3 amigos, amongst them a fault on the shuttle valve switches in the ABS modulator.
Whatever the cause, the only sure fire way of finding out is diagnostics. As to your Hawkeye trouble, another TD5 to plug it into could go some way to faultfinding, or borrowing another Hawkeye will help finding out where that particular problem lies.

the loom you need is injector loom amr6103

Thanks for all your replies.

I'll wait to see what Omitec say about the Hawkeye. Whilst I'm waiting, I've removed the ECU, cleaned the red connector. Even though the car is running fine, I'll replace the injector harness now. I may even get a couple of ABS sensors as I have a feeling, that's what the problem is.
