Strange fault D4

[scarry]

Haven't spoken to the dealer yet,but the D4 has been intermittently bringing up a message something like 'cannot detect smart key refer handbook'.It only happens occasionally when the engine is running & the passenger door is opened.Happened on the farm when the passeneger gets out to open a gate,when door is closed,the message usually goes away.If it doesn't go away,opening the passenger door & then shutting it makes the message go away.
I didn't want to turn the engine off & see if it would start as we were in a remote area.
The key was in the centre console,and moving it around in the vehicle did not change the message.

Hasn't done it for the last 4 days,key has been in same spot & we have had the passenger door opened many times.

Anyone had this type of fault?

Change the battery in the key remote. Instructions are in your manual. Battery World have the battery. I think they use the same size in the Prado, so your local Toyota dealer may carry the correct size as well.

Hi Paul,

I've had that heaps in the almost three years I've owned the car. But never tied it down to a specific event.

My D4 is quirky, electric windows do weird stuff....open a door when they are running to close and they open again. Applying the handbrake can do similar things. I don't like it, can't get LR to find out why, but it now doesn't bother me.

Small price to pay for a freakin awesome car.

Oh, just to give you confidence.....I've never had an issue turning the car off and it finding the key on restart.

I now carry a spare battery in the glove box.....they don't give you much warning. You can get the battery in chemists and Mr Minutes etc....anywhere really.

However, not fnding the smartkey without a battery warning in mine is just a quirk. I've changed two batteries in 3 years and had the warning dozens of times. If you have anything that is wireless or bluetooth, you'll know...they all stuff up on occasions.

Hope this helps,

Kev.

BTW....still give LR a call.

[PKD4]

Paul,

I have had my D4 for 6 months now and it has happened only once to me, can't speak for when my other half is driving. Similar you, it happened when car was running and I had got in and out of car and engine was running - key stayed in car though.

I could not clear the message, except by turning engine off and back on again but has not reappeared since. Thanks to other suggestions about batteries - I think I will get a spare to put in the glove box - easy insurance.

Yer i was thinking the fob battery,but don't think it was the issue.Another thing that was strange happened on Saturday last,the dash readout temperature stayed at 4 degrees all day.It was only 4 degrees early in the day.Since then it has appeared to work correctly.

The fob issue has not reappeared.

It probably will one day in some remote area.......:(

[LRTech23]

Hi guys, I work for a dealer.

This is a common problem, some do it some don't . Land Rover are currently looking for a fix for it. There's not really a whole lot we can do at the moment. I don't recommend replacing the battery until you get a "Key Battery Low" message on your dash.

Unfortunately it's something you sort of have to deal with, but with most cars it doesn't happen very regularly, hopefully there is a fix soon.

[LRTech23]

Just rechecked this issue, there has been an update dice I last checked it.

Land Rover engineering say te fault is cause by metallic objects such as laptops, phones, iPods or other inch devices interfering the with key signal.

Another reason they say is due to the position of they key itself. The best place to keep the key to ensure this issue does not persist is right next to the gear lever on the left hand side.

Hope this solves your issue!

[Tombie]

I concur, I have a laptop DC-DC charger in the vehicle (12v > 18v) which wreaks havoc with the key!

Move them apart and no worries...

Ipod chargers etc can mess with it too.

kind of ironic that statement isnt it :cool:

[Graeme]

Is that for RHD or LHD vehicles?

[gghaggis]

What if you're in reverse? :eek:

Cheers,

Gordon

[LRTech23]

This is for both RHD and LHD vehicles.

If you are still having issues, there is a receiver in the left hand side of the drivers seat in RHD vehicles, so you could also keep the key in your left pocket.

Lol, I'm sorry I don't think I understand the question.

The car will go to ignition position 2 or (ACC) mode if the car is in reverse but it will not start.

The car will only start in Park and Neutral when your foot is firmly on the brake pedal.

My attempt at humour obviously leaves a bit to be desired ................

Thanks for your info:)

No laptops,phones,chargers or anything else electronic in the vehicle at the time.
Oh,there were a couple of rifles one each side of the front seats,that is the console side of the seats.
Mine did it for a good few minutes while the key was in it's normal place in the pocket left side of gear lever.I then picked up the key & moved it around the cabin including holding it below the steering column,message still on dash saying can't find key.
Strange it hasn't done it again....
Also strange this has only started to happen in D4's,they have been out for a few yrs now?
Anyway,sounds like they are onto it.:)

[roamer]

Mine has done that a few times now just on 3yrs
I find if you just press the unlock button it finds it

Maybe that's why mine never has such problems!

[LRTech23]

Hopefully this helps, if you try these above tips you may need to take it to a dealer, but I'm not sure what they'll do.

But hopfully it won't happen again!

good luck!

[scarry]

Mine did it again today & would not start.Eventually it did,happened twice todayGRrrrrrrrrrr.Got it home.......

Suppose it has to go to the stealers:mad:

[scarry]

OK,back from the stealers,they washed it,that was a surprise,but i think i paid for it:(

They updated the instrument cluster,dunno what exactly was done,maybe replaced complete cluster,or just updated the software.Should also sort out the outside temperature indicater that has been playing up intermittently,and also the average fuel consumption that is also inaccurate.

Asked them to change engine oil & filter,that oil must have gold mixed with it........!

Anyway,they were very helpful & hopefully it will be all ok now.

[Graeme]

..Should also sort out .. the average fuel consumption that is also inaccurate.Wishful thinking?

[jonesy63]

At least the fuel consumption readout is consistently inaccurate! :D:D

[LRTech23]

Hahaha yeah, just so you guys know those fuel consumption read outs are CALCULATIONS ONLY. The car cannot 100% read the exact amount of fuel you are using. It is only there as a guide and should never be taken as fact.

Other manufacturers can get read out accurately so no reason LR can't do it right. It can be fixed using the right diagnostic equipment, so it's just LR choosing to give false readouts.

Brett...

[Graeme]

Adjusting my D4's fuel consumption fudge factor from its original optomistic +7% to a pessimistic -4% has made the calculation pretty much spot on for my driving.

[scarry]

strange LR can't seem to get it sorted:mad:

One of my brother's has a Honda something? which is about 4yrs old & it is almost spot on,that is average for a tank & calculating the figure from fuel used & k's driven.

My other brother has a turbo XR6,it's dash readout for fuel usage is also much more accurate than the D4.

And the other brother has a Prado,it's way more accurate as well

I can use a full tank on a long run,and it will say 9.2,where calculation gives 10.5.And this has been done many times.

Oh,and as Graeme says,bet after the 'fix',mine is still inaccurate.

My bug is what is the point in having something if it doesn't work correctly?

And on a vehicle worth $90k onwards..................

[Tombie]

As those above have so eloquently pointed out - you are talking rubbish :P All fuel usage is a CALCULATION.... Injector flow rate, Fuel pressure, Milliseconds of injection... Once these are known it is easily calculated... Take some unsolicited advice - You unofficially represent your employer marque here and yet provide some unique and often misrepresented information to the masses of a public forum. Keep learning and best of luck....

From what I have been told they are calculations. I'm going to sick by that, but feel free to have your own opinion.

No point quoting verbatim if you don't understand the context or the reasoning or logic behind a statement. ;)

Even the simple act of "I drove 200kms and when I topped up I put in 20 litres - So I get 10l/100km" is a calculation.

The vehicle is set to do the same, it knows how many times the injector pulsed, how much fuel flows for a give pulse length and calculates it from there. If the formula used is a little off, that can cause a miscalculation, but as noted above, a tweak to the CCF can fix the calculation and render the display accurate.

[LRTech23]

Yeah that's a fair point I would say, there are a million things that could throw off the calculation.

[LRTech23]

But it is still just a calculation. Which is really the only point I was trying to make.

[jonesy63]

I would argue it is an approximation on a calculation! :angel::wasntme::D

[scarry]

In a D4,correct.

Many other vehicles seem to be able to have accurate calculations.:):p

[LRTech23]

You have to remember that even if you don't have the same tyres on the car that came with it, as in, wheel size, tyre size, tyre width and profile, the car will think it is travelling a longer or further distance depending in the tyres. This would easily throw out your fuel consumption calculations.

Correct,but in my situation it was way out with the OEM 18's,and the 17's i run are almost the same diameter as the 18's(within a couple of %).

Larger tyres make the car go further than it thinks so in that respect should help correct the calculation. However with original tyres the calculation is overly optomistic and as LR provided an adjustment factor field in the CCF, they should have settled on a more accurate factor. Instead LR marketing prefers to mislead the driver, that is until the driver does their own calculation.

Well that's probably true as well.

[Redback]

Cruise control is rubbish as well, taking ages to set at the speed you set it at, sometimes dropping 5ks before it engages, even more if we are towing, and it overuns about 2 or 3ks as well, LRs lame excuse was it makes it smoother when engaging.

Where as our daughters Amarok is instant, set it for 100ks and it engages instantly at 100ks, because it does it instantly, there's no slowing then speeding up, which is smoother and no overun like with the D4.

It has it's quirks but I still love driving it, I just wish LRA and some dealers wouldn't treat you like your stupid.

Funny, I don't have any key non recognition problems as it is in the darned ignition of my RRC!!
Who was the brilliant rocket scientist who thought up this key proximity nonsense?
I read an article a little while ago that the crooks have already developed devices to duplicate the key /immobiliser signals. My Honda Jazz has the old system and I love it. Key in ignition ,turn to the right , start. It has all the jazzy immobiliser stuff but it is transparent.

I wonder how long the fad will last or will it go the way of four wheel steering, the cassette tape, and several other fads.

Regarding this key proximity thing, if our key is in range, you can open the rear passenger door if the car is locked, you can't open any other door, just the rear passenger door, makes it hard to stop someone knocking stuff off out of the car.

The thing is, the alarm is pathetic, you can barely hear it and we certainly can't hear it in the house, stupid idea.

I have found the cruise control on mine to be seamless.

One touch almost instant application.

Far better than the Toyota two button application.

[Graeme]

CC activation on mine was rather ordinary until the last s/w update. It still slows on inclines and overruns on declines although not nearly as much as it did prior to the change that included fuel being cut totally on gross overrun.

Same as mine,did 70K this morning with it on all the time,almost perfect,better than any other car i have had.A few hills,but not biggies.

I believe no vehicles CC should be used in very hilly areas.

Interesting you mention the alarm, yesterday my 18mth boy got hold of my keys, somehow activated the panic alarm, very weak if that's the alarm, I couldn't hear it from the house.

I've had the lastest 3.0l gearbox updates, didn't change anything except for fuel economy and fixed some faults I was getting.

Yep, I find myself overriding the cruise just to maintain the speed, I'm only talking slight grades too, something that doesn't affect our Amarok at all.

I don't use the cruise in hilly country, I'm talking every day flat country driving.

I hope the actual alarm itself is louder, cause if it ain't, theives are not going to worry about bolting when the alarm goes off, cause no buggar will hear it:(

[Graeme]

Perhaps only gbox updates were done rather than whole of vehicle.

[PKD4]

Well, if nothing else, Landrover seem to be consistent in producing inconsistencies. Or is that what we call 'character'.

My cruise control is great. Easy to use and pretty seemless as reported by others.

My 4 year old set off my alarm a couple of months ago when fiddling with the key fob and it was pretty loud. I did struggle to turn it off.

Still, I would rate it as the best car I have ever had - I have only had it for 6 months, hopefully that feeling will continue.

My CC seems to be fine, about 1-2 kph drop on hills at 108-110kph but no overrun going downhill. In fact it behaves very much the same as my previous '04 Jag S-Type and '96 Jag Sovereign CC's
