| Towing Electrics - Re-programming ??? |
|
Hi all
I'm about to fit towing electrics to my 2007 D3 SE. In various other posts I have read about the necessity or otherwise of having the car re-programmed after fitting but I cannot conclude whether it is really necessary or just desirable to avoid untimely beeps and bongs.
I will be using the car for towing a caravan. I don't do any serious off-road activity.
Can anyone please summarise what issues I will have if I don't bother to get the car re-programmed.
I would welcome hearing from anyone who has NOT had theirs re-programmed.
Many thanks.

If you don't get the car programmed for tow-electrics everytime you reverse with the van on your Parking Sensors will bleep continously and if it's like the D4, the vehicle set-up for gear selection on an Auto box is also modified when the vehicle detects a trailor is connected e.g. you can use command shift to select a low gear down hill, then go back into D and it stays locked in that gear down the hill rather than changing up as soon as you put it in D.
I had a D3 with programming done from start, then the D4 was delivered and they'd forgotten to programme it so was done a month or two later and although you could live with it, I just got fed up of the bleepers, only found out about the other things later on. LRs are a fond memory, apart from the maintenance.

Hi all
Sorry for stealing this thread.
What’s involved in the re-programming?
Is it a dealer job or can it be done with a Faultmate?
Thanks

I had heard this as well. I fitted the electrics to my 07 RRS three weeks ago and no reprogramming was necessary. When I connected the trailer all worked as it was supposed to. Rear parking assist stopped and the trailer display on the dash also worked.
My car had never had the wiring attached previously.

Most D3 ccf i,ve looked at have had the tow bar enabled even when not been fitted so you may be ok there are some that have not been enabled and as said your get the bleeps from the sensors.
My advise would be wire it up and see how you get on

Thanks for your replies gents. Worst case, doesn't sound like there will be any issues that I can't put up with for a while.
I will fit the electrics and see what happens.

Tow bar electrics will work , trailer icon will work , rear pdc will disable when electrics are plugged in . All this without any enablements .
If you enable the towing ...it justs disables the terrain response knob when towing ... You can still lift / lower via the height button .
This is for the d3 ... There were some issues with d4 towing ... Which I believe have been sorted with a software update G4 Gone ...but not forgotten

I'm pretty sure the D3 has always done this anyway. Mine has always worked like this (with or without a trailer attached) 
I thought that the only thing that really got activated was the disabling of automatic height change (i.e. in certain TR modes and gear ranges) when a trailer is attached. 2006 Discovery 3 TDV6 SE Auto Buckingham Blue

If you have a VSK (Vehicle Specific Wiring Kit) fitted to the D3, there is NO re-programming to be done.
I would always advise fitting a genuine Landrover kit or one made by Right Connections Ltd,
http://www.rightconnections.co.uk/viewpage.php?page_id=7
Right connections make some great products which you can get through any Indespension store, fitted or supply only.
Professional towbar fitters, like Indespension, will nearly always fit a VSK.
The basic "bypass" relays are only suitable for basic or older vehicles.
These VSK's are usually simple plug in kits giving you good quality connections. No more nasty scotchlocks to damage your vehicles wiring. They will not void your vehicle warranty.
To my knowledge, the only Landrover that requires re-programming to enable the C2 function is the Freelander 2.
When you plug your trailer 12N plug in, the C2 function is enabled, rear fog lights should be disabled on the car, and the parking sensors should be disabled & you should also get a lamp on the dashboard to remind you that you are towing!!
The C2 function warns you if an indicator lamp fails on either the trailer or the car. The old fashioned audible buzzers that used to warn if a lamp failed only on your trailer are no longer legal in the UK, Germany & Austria.
The driver must have a warning if an indicator lamp fails on the car or the trailer.
With the C2 function, if an indicator lamp fails on the car or trailer, your indicator will usually flash at twice the frequency to warn you.
On many vehicles, plugging a trailer into the 12N connector will do far more that light up some lamps.
Some VW & Audi's in particular will adjust ride height, stiffen suspension & modify the braking performance.
Vehicles fitted with steering potentiometers & accelerometers in the rear will detect any snaking and attempt to automatically correct this, often applying steering and braking forces to keep yor vehicle & trailer straight. Mitsubishi Outlander Phev 4H 2018.

Programming is needed so the CJB knows when towing electrics are plugged in to disable fog lamps if ever used and parking sensors.

There is NO reprogramming (coding) required on the D3. You'd look a right twit asking for it to be done.
The vehicle is already setup.
Heres a bit of info if anyone is interested.
I.E. For the D3
Fog cut off is done via metal strip.
PDC cut off is automatic (when you plug in your 12n connector).
Coding is not required.
We have fitted towbars & wiring kits to the whole range of Landrovers & the D3 has to be the easiest.
Plug & play.
(Model) (Fog C/O) (PDC) (Coding) (Notes)
Defender 90/110 01/99 >> -N -N -N -Coding NOT required
Discovery II TD5 08/98 > 12/04 -N -N -N -Coding NOT required
Discovery III TD6 01/05 >> -ME -AU -N -Coding NOT required
Discovery IV TD6 08/09 >> -ME -AU -CO -Coding is required
Freelander I 07/98 > 08/06 -ME -N -N -Coding NOT required
Freelander II 09/06 > -AU -CO -CO -Coding is to Stabilise the dash mounted trailer flasher lamp
Range Rover 2002 > 08/09 -AU -AU -N -Coding is NOT necessary for 10/06>> models
Range Rover 2002 > 08/09 -AU -AU -N -Coding NOT required
Range Rover 09/09 >> -AU -AU -CO -Coding is required
Range Rover Sport 06/05 >> -ME -AU -N -Coding NOT required

Diag Coding: Compulsory (CO) Optional (OP) Not Required (N)

As I said before ...parking sensors are disabled when the electrics are plugged in ...NO proggraming needed
Fog lights ... I will test it out tommorow , but don't believe that's the case either G4 Gone ...but not forgotten
