ok I'm aware this is a commen fault with landrover I've investigated the site for answers torn in to the electrics this is what I have found and I'm sure there is something a miss here I'm sure interior works like so simple earth to body an earth from door triggers and a permanent live what I have found both interior lights seem to have 2 live feeds purple/brown wire and purple/blue wire and then 1 earth black wire
Now going by front light this is what I figured I should have purple/brown should be live purple/blue should be door trigger negative black is negative to body
So can anyone shed some light to why the purple/blue wire is live ????
Or if someone has the wireing diagram that would be great
Cheers in advance
 
Here's the cct from the Disco 1 RAVE.
From what I can see, there's a live feed to each light and the "override" switch is down to ground. The normal switching is done by the MFU, not by the door switches directly.

As you can now see, the purple/blue (PU) wires will be live due to the feed through via the other bulbs.
 
Thanks Brian that helps a lot seems I need to start looking deeper into the electrics now just looked into the mfu is there a way to test the mfu or is it best to just replace and Sorry Sierrafery I normally do but got a little hasty to post
 
Thanks Brian worked a treat was able to test the system interior light came on during test so I'm a little more confused if this means the mfu is buggered so will download a copy and see if I can figure out what is going on cheers Brian
 
Ok issue update my knowledge is growing by the day all sorted now found to be a broken door trigger switch bit weird really didn't consider 1 door triggers to have been the issue but would seem the mfu must have disabled interior light function thinking one door was left open constant only found by chance I lent on the door lock trigger while driving and doors would not lock as if one door was open
On plus side I now know that if the alarm bleeps when locking it's not normal and means I have an issue just hope that 3 flashes means everything is normal lol

It is normal, it's called "misslock warning" , a built in feature, so are the hazards on lock command

So for you it's not normal to do what it was set to do from factory?:rolleyes:... cos IMO it's normal to give the misslock warning as long as there's a closed to earth input on one of the door switch circuits:cool:

All I can say is read the OPs statement and understand the context, in that It's not normal for the D1 locking system to give a confirmation beep of locking.

I've read all the statements but i can't confirm i understood as it was intended.... anyway for me "confirmation beep of locking" is another dillema as the misslock warning(which that beep is) is not a confirmation of locking in my mind but a warning that the bonnet or a door is not closed well... though for the MFU this is a closed to earth input from one of the doors/bonnet circuits so it can be a wiring issue too ... and that would not happen on a locking command if everything is OK so NORMAL to me ... i can admit that this confusion can be cos i dont think in english :cool:
 
Ok start a the beginning. The OPs statement is "I now know that if the alarm bleeps when locking it's not normal" there's nothing wrong with that its correctly stated.
Its not normal for a D1 to have the bleep on locking, that would be a confirmation function, thats what some other vehicles have, also with an indication when unlocking, which can be annoying feature for some.

So the impression is, that OP knows that if there was a beep when locking it would indicate a fault ... and as we all know is normal, it's termed " mislock" .

Now back to work:)

I'm not gonna go into english semantics with an englishman :) ... for my non-english brain it would have been not normal if there was a problem at the bonnet/doors circuit and no beep on lock command cos as long as there was a problem the beep is normal :cool:

but for the issue itself that's irrelevant

I think what you're trying to say is that if there is a problem on the central locking system including a door or the bonnet not fully closed, a faulty door switch or faulty wiring it will be indicated by a "misslock" and that is shown as a single beep when trying to lock the vehicle. This behaviour is normal when a fault condition exists.
When the system is working correctly there will be no beeps, the doors will lock and the hazard lights should flash 3 times. This is correct and is NORMAL operation.
I think the semantics problem has come about in the effort to equate correct operation with normal operation.
 
Hey sorry for confusion it's was ment in context that's it's not normal to be beeping all the time only when there is a fault I originally thought it was ment to beep to let others know the car is alarmed like an aftermarket alarm keeping in mind I only bought the disco recently and it had always done it since buying it lol
