just driving and ping ping eas fault with all lights flashing on switch and dash light picture of rr with arrow on. Looks like compressor is running as it is hot not sure if it cuts out though. Any ideas thanks jeff
 
Get yourself the Diagnostic Lead and software from Datatek (member on here) he sells them for less than £20 I believe....

Plug your vehicle in and read the faults....without diagnostics we could be guessing til noon next Saturday....

Most likely feeding a leak, time to get the soapy water out and check the bags and pipe connections!

+ 1, I have had similar happen when I unloaded the car after carrying loads of ceramic tiles, think it took the height sensor's out of their normal travel range. Plug in laptop and reset cured the problem:)
 
As it's gone to wading height it's a soft fault, next stage it will drop to the bump stops and go to hard fault. Diagnostics is the only way forward. PM me for details.
 
Thanks all, I do have lead and cd, but laptop has no serial and no cd drive, one of those little useless laptops. So I may just have to get a old laptop that will do the job.
 
Thank God I do not live in the centre of Brighton but just at the downs. I bought the RR as I am going back to France to live, lived in France for 7 odd years then 1 year in Austria and then came back to UK. Now after 1 year in UK decided to go back to France where a 4x4 is needed as when it snows I cannot get out until it thaws a little and have a steep track to get up. Snows not the problem but the compact ice underneath. Also the RR will be useful on the land for pulling things out and around. Anyway to day the system is back to normal, so whats going on there then.

Again, diagnostics!!

As I said, it was a soft fault, quite likely a height sensor giving a duff reading, you still need diagnostics. Mine's pretty reliable but I would never leave home without the EAS diagnostics just in case.
 
Today during round trip to Ferndown (185miles), I had the "random high mode" about 5-6 times. Four times I managed to press the down switch in time and avoided the fault mode, but twice I missed it, and EAS went into fault mode. Reset each time with Nanocom & continued journey.

So for the last 50 miles I thought, lets try data logging on the Nanocom and catch the fault. . . . . . no further problems . . :confused: so my wife says "just connect it when you drive !

Does Nanocom usually prevent EAS faults while connected ?

History:
Already bypassed the white connectors in left footwell:- soldered joints instead of green corrosion.
Connectors in engine bay look good. Still need to check sensor connectors.
Compressor seals & piston seal replaced 3 weeks ago:- good pressure before & excellent now.
Replaced all seals in Valve block yesterday:- no more leak from exhaust outlet.
All height sensors give similar readings on Nanocom at all height settings. . . might be glitchy, but does't look like it on Nano.
------------------------------

I now suspect driver pack strangeness but being an electronics engineer, I want to investigate rather than part-swap.

  1. So, firstly does anybody have an internal diagram for driver pack ?
  2. Are the 12V switched inputs from ECU filtered for vehicle noise ? (maybe the capacitors have dried out)
  3. Do the height sensor inputs to ECU have sensible low-pass filtering ? (I'm sure the ECU does not need to know every small bump on the road)

My thoughts are to start fitting additional capacitors to the ECU & Driver Pack inputs to remove random vehicle electrical noise. Many years ago I designed a variable wipe system form my old XJ6, and you would not believe how random the wipers were until I filtered the electronics properly.

BTW, In case anyone finds it useful, I just uploaded the Land Rover "EAS - System Information Document" I found on Nano forums, to the EAS sticky section in How-To's.

I've got a spare driver pack in the shed if you want to borrow it for testing voltages and so forth? Your location says Heathrow. Do you come up near Bucks much? Alternatively my brother's down that way so I could see if he's willing to deliver a parcel next time he's passing.
 
I seem to remember a post somewhere from a guy who had troubleshooted a EAS computer and driver pack. Might have been on RangeRovers.net. It was very detailed and interesting. Cannot remember exactly where now.

Someone on here had made their own EAS controller out of an Aduino or something. Might be worth a PM?
