Thats the main fuse that land rover charge the earth for if it blows..You have to buy the complete cable with fuse.I have in the past just bought some off ebay and bolted a new fuse inline, does the job and saves you pounds lots of them..

hello all! thanks for your time and energy here.
just to sort of piggyback on gstuart's info:
i am using both NANOCOM EVO and FOXWELL tools.
the laundry list of codes provided was pulled *after* the truck had entered crash/emergency mode.
if i do a code reset and the truck isn't in crash mode, i'll only receive faults from the EAS ECU.
citing all of the "incompatible software" faults, i have reflashed several ECUs: RLC, TCM, HVAC, ATC, IPC, probably more...
i have used the foxwell VEHICLE RESET numerous times, but it can't exit crash-mode. all it seems to do make the cd changer make lots of noise.
i'm currently inspecting the under-hood fuse box where the compressor relay socket seems to have endured a little bit of melting... i physically inspected all cabling and connector at the EAS ECU. replaced all splices in driver/pass door sill loom. the photo of water trails is coming down from the heater core adjacent to the glove box fuse box. i've shined a light all up in there and don't see any evidence of water trails on the A-pillar or firewall, just the heater. there's also evidence that up to 1.5cm of standing water has existed in the door sill looms, but it's been outside on a slope in the hardest rainstorm of the year without any ingress.
i've inspected the body harness connection near the rear wheel, seems fine. next stop will be the harness within the front fender well.
will be happy to chime in with add'l info as required.2010 NAS Disco 4 HSE LUX HD petrol

Many thks, havent seen one before so that’s why i thought it was a battery monitoring sensor
Most appreciated
Ref the codes u mentioned that need sorting , what does PO mean plse

Hi buddy
Great u found the link ok, as indeed know there is a vast amount of knowledge here and everyone is so helpful , covering as many bases as possible
Sounds like you’ve been busy
Indeed see what those 3 x connectors are like
Meant to ask what error lights come up please on ur dashboard
Many thks

Well I believe I have two issues... one may be symptomatic of the other though.
If the truck is behaving (not going into crash mode) then I get a single chime and an amber suspension light (never red). Occasionally this is accompanied by Special Operations Unavailable or whatever that message is. When I don’t get the special error, I can still select various terrain modes or hit the raise button, and the vehicle will indicate that it’s lifting but it never does obviously.
When it goes into crash mode, the dash lights up like a Christmas tree, with HDC, EPB, ABS, and whichever other systems it feels like. It’s rarely the same but it almost always includes HDC and EPB.
If I clear all codes and can stay out of crash mode I’m only pulling one code from the EAS, but after a crash mode session I’ll get 40ish codes from 15-20 different modules.2010 NAS Disco 4 HSE LUX HD petrol

Hi
Where u had the bad connection under the suspension relay have u cleaned it up and fitted a new one or not had chance yet
Have u pulled every fuse to ensure there sound in the engine bays fuse box , inc the J fuses , don’t know if ur aware but can remove the plastic covers on the J fuses and test them with a multimeter
However , I expect you’ve already done that
As u fitted the new hitachi compressor have u disconnected the power connector plugs and put 12 volts directly on it to ensure it’s not a faulty new compressor
Also when u remove the front wheel arch liner it might be an idea to do a continuity test from the front connectors to the ones at the compressor / reservoir valve block and pressure sensor to prove there sound
Remember u saying you’ve done the following
What I’ve done:
Replace brake switch
Replace brake lamp bulbs
Replace battery AGM
Replace air compressor (hitachi version replaced with hitachi)
Remove/inspect/resolder IC plug

Confirmed all fuses. Compressor relay socket is melted but it won’t be until this evening that I have a chance to figure out how to fully open the box and inspect.
Compressor (old and new) are sound and run well on bench. All of the wires near the compressor plugs have had the insulation stripped a little so I assumed they tested out... I can double check for voltage and continuity when I pull the fender liner. I’ll have to put a few things back together a little bit first because I’m running out of space on the garage floor for new piles.
I also need to look at the back of the cabin fuse box but that looks like a real chore to get out.
At this point I’m not sure which came first, the suspension fail or crash mode... maybe crash mode is due to a medium speed can bus failure on the EAS segment of the bus. Maybe the EAS failure is caused by whatever’s causing crash mode.
I’ll get there sooner or later, and appreciate everybody’s unique experiences and POV.2010 NAS Disco 4 HSE LUX HD petrol

Hi
Easiest way to get that fuse box apart is that bolt at the front, snip the cable ties very carefully at the back then lay it on its side , u can then release the 4 x tabs and the bottom will slide off
With the fuses removed u can lever the top plastic sections off to inspect it
Will find some pics for u when I done mine
Ref the inside fuse box, wonder about one if the cheap ebay endoscope that work with iPad, to see if u can see behind the fuse box, heard there suppose to be sods to get out and back in again
Great it’s been bench tested , but if I remember rightly it didn’t show the correct pressure when installed, assume that’s because the system shut down
Always the way when u turn round and end up with half the landy on the floor when trying to gain access to items
Fuse F 26 is the compressor fuse , daft question have u tried removing the fuse so the suspension is disabled , then rescanning the system to see what fault codes come up , trying to think if it will narrow the search down in the way of elimination ???
Alas don’t know if u can do that with other ecus , by removing them and then rescanning ???

Some more pics, u may have seen some before , I bought a second hand fuse box for the heated jet retrofit
Hope fully they will help

There are crash sensors around the vehicle - someone may know where they are. I am interested in how it goes into "crash mode", is it something you do? or does it do it on its own.

There is no rhyme or reason to crash-mode. It’ll be fine for hours and then be in and out of crash mode every other start. There’s nothing I can do to make it go in or out of crash mode. Sometimes it starts fine and goes into crash mode while running, some times I power it on and it’s already in crash mode. If I leave it and come back to it in 30 minutes or so, there’s a fair chance it will come out of crash mode, but it’s no guarantee.2010 NAS Disco 4 HSE LUX HD petrol

That indicates a bad crash sensor or connection to a crash sensor

Hi
I think there’s some confusion , The crash mode is technically the air bag system, think what ur talking about is limp mode
When a faulty airbag or sensor activates ur see an airbag light show up on the dashboard , then sends a crash data message to the airbag ecu that’s sits underneath the centre glove box, inc some gyro sensors
Alas experienced this when I first bought mine, previous owner had cut out curtain airbags so ended up quite a long job to resolve
There are impact sensors around the landy
2 x each side at the front , near headlights
2 , each aide in each front doors
2 x each side at the bottom of the B pillar
2 x each side behind the boots side locker
Black impact sensors are for the front bumper area , red sensors go inside
After the ecu has logged an impact it’s has to be reset via dignotics, after I repaired / replaced some curtain airbags the gap iid allowed me to reset the ecu , which in turn put the airbag light out
however the crash data will still be stored in the ecu and has to be retrieved by a specialist
Sometimes diagnostics won’t allow u to clear the crash data signal , then I believe the ecu has to be replaced , luckily the gap came up trumps and reset it
Hope that helps

This may help for wire tracing. I think it will go large when you click on it, if not its in my gallery.

Hi
Did send some of those pics over
Also an electrical library manual, shows where all the connectors are , after downloading it if u press on the blue descriptions it will show that page
