    Nanocom to Diagnose Air Suspension Fault

    Belated Update With advice from other threads in this forum I successfully replaced the height sensors and air suspension units at the weekend, so thanks to the posters concerned. it is however worthwhile making sure you have four new 10mm M5 flange hex bolts before you remove the old...

    Nanocom to Diagnose Air Suspension Fault

    I appreciate how the SLS is supposed to work sierrafery, it's just that my SLS seems to have forgotten....... And at the risk of exhausting your patience, just one last query... Would you recommend connecting the negative lead to the negative terminal of the battery or to the car body... or...

    Nanocom to Diagnose Air Suspension Fault

    I realise that now.... just didn't think something with that small a point of contact would fuse so tightly... i assumed the body was sticking.... But this is a big learning curve for me, so your help is appreciated.... and if you feel like giving a tutorial on how to set up the kind of parallel...

    Nanocom to Diagnose Air Suspension Fault

    Thanks again sierrafery... never thought of using anti-rust spray on plastic connectors, but I'll give it a go.............. And I'm not sure I have enough knowledge to improvise the wiring you suggest, so maybe I should just stick to your second option. But thanks again for your help.

    Nanocom to Diagnose Air Suspension Fault

    Not much progress due to the freezing weather. Highest temperature today was -1........ The only fault code I get when I switch the ignition on relates to a faulty ABS sensor on the hub that was replaced by a garage a couple of months ago. Not relevant to my current problem, but something for...

    Nanocom to Diagnose Air Suspension Fault

    Thanks again for the ongoing advice sierrafery. There were no fault codes stored and I haven't touched any of the components inside the compressor housing yet. Just a visual inspection. I'll take a look at the ecu plugs as soon as I get a chance. The weather at the moment doesn't exactly...

    Nanocom to Diagnose Air Suspension Fault

    Thanks sierrafery, that's what I was beginning to suspect. Any ideas on how I can test the ECU if I pull it out? I've got details of which pins are connected to the valves. Or is it really a job for an auto electrician ...if I can get one to come out into the wilds... or for my main dealer?

    Nanocom to Diagnose Air Suspension Fault

    Done all that. With the engine on and running, all I get when I test the valves are readings of 0.00V or 0.06V. And the reading across the relay is 0.20V. Same readings with ORM selected... or when using Nanocom to inflate the bags. Zilch. Nothing. The fuse is ok and the relay seems to be ok...

    Nanocom to Diagnose Air Suspension Fault

    Thanks guys, but I know the bags need replacing. I had already bought new bags and new sensors, BUT........ on the Friday evening before I was going to replace them the car developed this additional fault. And there is no danger of the compressor burning out coz it's only running for a few...

    Nanocom to Diagnose Air Suspension Fault

    Thanks thebiglad, but that was my first thought. I don't think you can imagine how many times I have gone around that vehicle opening and shutting all the doors...... Also the Nanocom says that the door switch is closed.

    Nanocom to Diagnose Air Suspension Fault

    My issue is that I can't get any of the valves to open. When I start up the engine, the compressor runs briefly but neither of the inlet valves open and there appears to be no voltage across them. Then after a few seconds the compressor stops working. The car is sitting low due to a leak in...

    Disco II Air suspension – the definitive guide

    Hi All. I asked this question in another thread, but it's probably more appropriate to ask it here so I hope I'm not breaching any site etiquette by asking the same question in different places. I've got a 2001 TD5 with air suspension problems. Using the excellent advice and guidance on...

    Nanocom to Diagnose Air Suspension Fault

    Thanks for the offer of help Ahaggar. I had read about the "Transport" problem before and I'm aware of that. I think I must have some kind of electrical problem. My problem is I've never used Nanocom on the SLS while it was working properly, so I don't know what responses I should get to the...

    Nanocom to Diagnose Air Suspension Fault

    Well that's very encouraging to hear Ahaggar.... but have you ever used it to diagose faults on the air suspension or to inflate the bags? I'm having a few problems and would appreciate some guidance. Thanks.

    Thanks for the welcome ...and if I can keep my Disco going for another 17 years chunkymunky, i'll be a very happy bunny...................... but probably even poorer than I am now.......

    Nanocom to Diagnose Air Suspension Fault

    Does anyone have any experience of using a Nanocom Evolution to diagnose faults with the air suspension on a Discovery 2. I've just got myself a Nanocom, but I'm having difficulties interpreting the results of my tests.... voltage readings across the valves and relay.... and I'm not even sure...

    Another Rear Air Suspension Thread.....!

    Tried operating the compressor and the valves individually with no joy. Suspension didn't rise at all. Got readings of 0.06V across the valves and 0.20V across the relay during this test. Anyone have any idea what the readings should be? And I have to admit I may not have been using the...

    Another Rear Air Suspension Thread.....!

    I would if I had a towbar........ but thanks for the advice. I'll try it on axle stands. And I've just got hold of a Nanocom Evolution. This is its first test.... so I don't really know what I'm doing yet. I connected it up and there were no faults showing for the SLS.

    Another Rear Air Suspension Thread.....!

    Hello all. New member here, but one who has read this forum before and used the advice to identify and repair problems with the airbags and sensors. Sorry if I'm going over old ground, but I seem to have a new problem and would appreciate some help with diagnosis. One of the bags on my TD5...

    Yet another poor misguided soul....

    Thanks Nick. But if this how it is while it's still a baby... what's it going to be like when it becomes a teenager?
