I've had my LR3 since October 2009 but it's a 2006 and recently I've been having issues after starting the car.

Upon starting the following lights appear in the dash:
Low range light-flashing green
DSC- solid amber
BRAKE- solid amber
With the messages:
SYSTEM FAULT SPECIAL PROGRAMS NOT AVAILABLE
HDC FAULT SYSTEM NOT AVAILABLE
SPECIAL PROGRAMS OFF
Also, the range selector in the center flashes

A little background info on the problem: It first occurred after lowering my suspension with the engine off, which is a normal function. Then it happened on my way back from a river trip in Arizona at a gas station on a normal start up. It has happened increasingly since the first occurrence about 3 months ago but goes away after restarting the car. I took it to the dealer to get new rotors and told them about the problem and they suggested a faulty battery, but could not get the car to do it for them. I drove it home (1 hour drive), got out for 5 minutes, then got back in, started the car, and the lights came on again. Feeling a little frustrated, i restarted, but the lights came on again. This was the first time it happened continuously. After about 8 restarts, i called LR Miramar and they "apologized for the inconvenience" and suggested I drive another 2 hours to drop it off again (no), so instead I had road side assistance tow it back to them. I didn't want to drive a car with faulting brakes and transmission problems. I currently await news from them.

I can email pics and a video of the problem (can't post from my iPad)

UPDATE:: Just got the car back from the dealership. Its getting towed back tomorrow. Their diagnostic tests found a good battery and no corrosion or open connections in the wiring. The suspension is now acting up and lowering to access height along with the SUSPENSION FAULT message. Also getting a TRANSMISSION FAULT message. Lemon perhaps?

Please let me know what you find out. I too have an 06 that I purchased in 09. We are having very similar issues. i am new to this site and I dont think I have configured my profile to notify me of a response. If you dont mind, email me direct at [email protected] if LR is able to figure out your problem.

I posted my problems back on 7/12 and have recieved very little feedback.

Thanks!

With electrical gremlins, it is best to start your troubleshooting with the battery. Given that the LR3 is a highly electronic vehicle, lack of battery juice can cause all manner of error messages to appear. Based on the age of your vehicle, a battery change is about due if one has not already been done in the past couple of years.

Jkhazraei,
This sounds very like my problem with my transmission module. If you take the battery out behind there you will find a small plastic flap, this folds forward and behind that is the transmission module. If you see any water or corrosion around the multi pin terminal block that's the problem. I'm not sure if you've heard of Blackbox Solutions, they operate out of Cyprus, they do a unit called a Faultmate MSV 2 which you plug into the D3 com port this helps you diagnose problems like this. If you replace the Tranny module you have to reset the hand brake clutches, this unit walks you through this process. Other than this suggestion you might take the D3 into your local agent and ask them to check the condition of the multi pin connections on the transmission module. This first happened to me after I gave the vehicle an engine bay wash, a definite lesson learnt here....... I'm really paniced when I first turned the vehicle back on and all these lights came on and told me an awful lot of "stuff" suddenly stopped working.
Hope this helps.

I sold my LR3, but the dealership did seem to solve the problem after the third week long visit a few months ago... If anyone has this problem in the future, you can PM me and I'll try to explain what the dealer did. It was a very long list of car parts I've never heard of, so I don't want to type it out right now.

I have recently had the same sequence of problems. I have a 2008 lr3 se. I changed the battery out for a new one, that did NOT fix it. I then took it t my local mechanic (not LR) he cleared all the codes and one kept comming back, rear brake light fault. We then checked the fuse it had blown!, replaced it cleared the code and now good as new.

Probably just a faulty brake light switch or bulb.

Review the link below.

Everything does not crap out all at once on any vehicle; even a Land Rover; it is just the computers reacting to some minor fault, most likely a faulty brake light switch or just a burned out or defective tail light bub. Did you recently install a non LR bulb?

DISCO3.CO.UK Photo Gallery - Brake Light Switch Replacement

Also as above in other posts, a bad battery is another common problem - the 3 is the worlds first electric 4x4 - well it seems that way.

I had this same issue for several years before I was able to resolve it. The issue was a broken ground wire located behind the driver’s side lower trim panel (LHD). It was intermittent until the ground wire completely wore through.

You will need to remove the foot rest and bonnet release in order to remove the trim panel. There are three grounding lugs directly beside the area where the foot rest is located. The ground wire to one of these lugs was rubbed into. Presumably from rubbing or vibrating against the inner panel. I repaired the faulty section of wire and haven't received a single error in over a year.

I have had this problem going on for about a year now i have an 06 LR3 HSE and initially the dealer replaced the transfer case ecu, rear light bulbs, and said they repaired several corroded wires, this fixed the problem for several months then the issue came back, this time they replaced the brake switch, but said they couldn't pinpoint if it was the switch or the wires on the other side of the circuit. The issue occurs a lot less frequently but still does happen, i would be very interested to know what the ultimate solution for you was.

Own a 2005 LR3. VERY EARLY American production. Same code problem periodically reappears, then seems to "self heal" only to appear later. Battery voltage was 12.94 volts this morning (used a VTVM meter). Am receiving other messages which come and go. Seems to be a slow progressive failure in the system. As I understand it, there are 33 computers throughout the vehicle and under the two dash boxes is a fuse panel with close to 200 fuses. So the problem could be anywhere ... a great mystery. Yet, when I had a leaky thermostat housing, the diagnostic software nailed it correctly with the appropriate message! Unfortunately, Land Rover Policy seems to be to update software ONLY FOR SPECIFIC FAILING MODULES. Instead of upgrading ALL software as the patches come out. This is a VERY SHABBY practice. When I am working on computer systems (all the time!) I ALWAYS install every patch. Maybe a joint bitch to Land Rover will get them to move off of their butts and upgrade software correctly. Who knows, most of these messages may disappear with the complete software upgrades.

Dealer did find a suspension fault and replace a few components in the air suspension system. I routinely use a fault detector plugged into the diagnostic port, but it seems to report mostly generic automotive faults, not the ones which flash on the dash. Land Rover seems reticent to release codes to the diagnostic instrument manufactures ... to bad, as it lessens our ability to see what is failing.

Very similar prob. 06 lr3. Changed the battery, the brake switch, lights are good. I narrowed it down to the wires beneathe the passenger side door sill. When i jiggle them i get the fault. Anyone else have this prob?????

It was a bad splce under the passenger door. I think this should be the first thing to check as it was very obvious when you know what to look for.

It would be notably important to describe every symptom, and every light, including the sequence when possible. I did not see a mention of suspension lowering which is typical of the brake light switch problem. One thing in my opinion is worth consideration for those of you reading but have not yet experience problems.

There are a number of problems which will eventually pop up, so rather than waiting until the most inopportune time for the failure, be a bit proactive now.

You will need to replace your brake light switch, so replace it now, keep the old one for a spare if you haven't experience any problems yet.

If you have ever replaced a tail light bulb, and did not use a genuine LR bulb, just go ahead now and replace all the bulbs with genuine LR bulbs. Any working bulbs you can keep as a spare. A blown brake light bulb will cause many of these symptoms. Unlike, say a Lexis, that puts a light on the dash to say a light bulb is out, LR practically disables the vehicle because of their engineering creativity or dry Brit sense of humor.

Check your battery, ground cable, terminal, cowl. Batteries have reported lasted 2-5 years, I am in the 2 year category. A battery not operating at the proper voltage causes a cascading effect of meaningless failures, glitches and error codes, none of which indicate a bad battery. Perhaps in future centuries, LR engineers will decide that, IF the battery voltage is lower than X at start, and Y and run time, and the following errors are tripped, light up the Battery light.

The negative terminal is prone to corrosion which also contributes to corroded the negative terminal as well. This should be checked, cleaned or replaced and sealed. You should also check the negative terminal connection where it bolts to the body.

I have read about this wire problem now several times, so it seems like it is time to tear it apart and try to prevent that. It would be great for someone who has done it to post up some pictures.

It would be best to be proactive in checking and maintaining these and many other items, instead of waiting for failures. It is pretty well established, that we will all eventually have the same failures, even the tailgate failure-- which I thought wouldn't happen to me, did at the worst possible time. It is much easier to order a few inexpensive parts and do some maintenance ahead of time.

"Defaults differentials to HDC system, DSC, suspensions"

(new member) I've noticed that looking threw the posts that we all had similar problems without the answers? I've had about everything come up on the on-board computer each time i start the RR 2006 v8 4.2 model, this started about a year ago..., the car had even gone into security mode stuck in 3rd gear restricting speed etc.... If you listen to the RR experts each garage have a different version one said i had to take the whole front apart to line up all the sensors, another said i had to change the gearbox etc... don't trust any of them specially in France... I forced the key a few times and it switched everything off deleting all the faults and back to normal... A garage in the UK say its the ignition & needs changing (bad contact) or can this come from the automatic gear leaver (sensor) etc...? recently the problem is back... Any ideas inbox me pls?:)

There are plenty of suggestions in this thread as well as lots of other places on this forum and many others.

How many of the symptoms and things to check have you gone through and checked?

No, but your 3 does have air suspension.

. Lemon perhaps?
No, but you have purchased a vehicle that not only has air suspension, but has a downhill decent restraint function. More systems means more problems.

The good news is that the numerically more nasty fault messages you get at about the same time, the less serious the problem. Land Rover did not put a message in that says "broken wire" or something similar. As such, lacking in vocabulary, you get a string of other messages from a not very smart computer of which none define the problem, but do very much annoy oneself.

This is the reality of purchasing the worlds best 4x4 that in stock condition will go places no other stock 4x4 can go, be it the opera or Pikes Peak. That sort of performance and versatility comes at a price.

Check in both front wheel wells for frayed suspension wires - sometimes the air suspension cable harness to the height sensor comes loose from the frame and the tyres cut the cable harness during a turn when the tyre and the cable harness touch. If you are lucky, the fix while not necessarily cheap, is simple - and LR makes a repair kit for just such an eventuality.
