My 2002 D2 has decided to annoy me. AGAIN.

[Markf]

Does anyone have any ideas please. My 2002 D2 auto is behaving strangely (badly).

It is, at random, giving me the 3 amigos. This, of course, is no strange thing in a D2 but what is unusual is that there are no fault codes. I've even tried updating my nanocom ...

The only work I've done recently is to replace the serpentine belt tensioner and about 3 months ago the injector seals and washers so I have nowhere amigos related to get me started.

Anyone have any ideas bearing in mind that I will not be blindly replacing things that [B]might be the problem.

Oh well, it is a D2 and I suppose it is character building and it is teaching me patients and tolerance.

Failed SLABS ECU or an earthing problem.

Undo and clean all the earth points between the fuse box and the battery.

That's about all I can suggest.

Hi - How good is your battery. Mine recently started to play up - 3 amigos etc
Battery had seemed to be ok, but then i noticed it was getting slower to turn over

I replaced Battery - and the problems disappeared.
perhaps a battery load test??

cheers

Shack and Nobby I have already been down the check all ground connections path and just this very morning I got the battery back from being tested uphill and down dale. The end result is that the battery is good and all the ground connections are bright and shiny and clean as are all the fuse connectors. I was starting to think my labours had been successful when "bing bing bing" and my friends were back. I was even starting to think I may have an actual fault recorded but alas the old no fault found mate was still there.

Shack, I'm starting to think the SLABS ECU may be the only culprit left - aside from just waiting until a fault finally shows up.

Is there much jiggery-pokery involved with changing the SLABS ECU ?

[Tins]

I'll add my little bit. Check the inside fusebox. They are known to corrode, and mine caused many kinds of weirdness with warnings and things not doing what was expected. Reasonably common issue. Pull it out and check. It's not as hard as it looks. And it doesn't take much green muck to make it go stupid.

Not really. Pull the glovebox lid off and it's up there. Some swearing will have it out.

And THAT is most certainly worth checking out. A few months ago I had a "wet carpet" episode when the roof rail sealing stopped sealing... The leak has been fixed but I haven't had a look at the fuse box. That's on the agenda for tomorrow.

With replacing the slabs unit, you will need a Nanocom or similar to select air suspension or not, and if you have air suspension you will need to enter and save the height settings from the original unit.

I'm not 100% positive that it is the SLABS ECU, but if you rule out everything else, it's likely the problem.

Try to get a late revision unit, they are better and also had better fault tolerance as well as slightly different behaviour with the CDL engaged (if you have one).

That'll do it.

I had one last year that was setting of the amigos on light application of brakes (squealing must've hit the right frequency)

I had one last year that was setting of the amigos on light application of brakes (squealing must've hit the right frequency)Would that normally log a fault though?

It's a long time since I had any issues, I've forgotten what I knew!

No faults logged, ditto with issues, D2 related ones anyway.

[shack]

Markf,

With Discorevy's comment in mind, it would pay to see whether braking triggers the fault or not, even if it does it may not do it every time, but if it only ever happens when braking, that would be a good indication.

[sharmy]

The brake light switch on these used to cause all sorts of problems especially if its the original unit. An updated one came out at one stage and was less problematic. they are easy to change.

[Markf]

It's been a while but I have got to the bottom of the issue.

Believe it or not it was an intermittent battery of all things.

I was going around all the various boxes, connectors, etc. and tapping them with a 4oz dead fall rubber mallet seeing if I could disturb a connection somewhere to the extent that it caused the fault. No joy...[bigsad] It didn't matter what I hit the issue wouldn't raise its ugly head and then I'd go for a drive down the street and low and behold 'bing bing bing + 3 amigos". AAARRRGGGHHH...,

Anyway for some unknown reason I tapped the negative battery terminal. "bing bing bing 3 amigos" Hmmmmmm. Retightened the battery terminals and the 3 amigos went away until I tapped the negative terminal. "Bing....". Disconnect battery and reconnect and all is good. Tapped negative terminal and back they came.

A few days ago I had the battery replaced after demonstrating the problem and since then the issue has gone.

Problem solved. Land Rover electrics can certainly keep you on your toes. I wonder what's next......[bigsmile][bigsmile]

Thanks for letting us know, Mark.

John, Is this a clean up and refit, or is a replacement required?

[Tins]

John, Is this a clean up and refit, or is a replacement required?

Clean and refit in my case. Fairly straightforward. Hardest bit is getting the plugs out.

[Tins]

I used IPA and some electronic contact cleaner and some gentle sort of lacquer to try and seal it, but you have to be careful with PCBs.
