A few weeks ago, I had hooked up to my caravan and switched on all my lights to check they were working. I walked to the back of the caravan and they were going through a sequence showing each set of lights one after another. I have no idea what I did to produce this result but it was a great help in doing this routine check. Unfortunately, I have been unable to repeat it. Has anyone any idea how to do this?

If anyone is still interested, it has taken me nearly a year to find the solution to this conundrum. I have found that if I switch on all of my lights, before hooking up to the caravan, the lights go through a checking sequence. I am not sure if this is due to my Freelander wiring, the new hitch and cabling or the caravan wiring but it works. It has made hooking up on my own far easier.

Not heard of that one.
By all lights, what do you mean?
The factory trailer module is connected to the CAN, so only does what it's instructed to do by the CJB.
I've not seen a light show on mine, but then I generally don't connect the trailer plug with the lights on. Mine has a genuine trailer module and harness installed.

Hi, by all lights I mean they go in a sequence with each set of lights going on for a few seconds one after another. It is then easy to see if one or both bulbs are not working. Lights, brakes, signals, fog and reversing. All one after another. Even my 7 year old grandson can now check them for me. (Although I still do a quite look myself). I have no idea what your talking about on the CAN or CJB so cannot help you there.

I appreciate this is an old post, but I know the answer and have posted how to turn on this feature, assuming the loom has it.

It’ll be the tow electric loom. Assuming it’s a 13 pin (maybe 7pin?) and aftermarket installation or upgrade. I installed Towbar and electrics ( Land Rover specific from PF Jones) to my 2008 freelander2 and it came with a self test function - invaluable for solo caravaning.
BEFORE connecting tow electrics to the car and with the car TURNED OFF.
1. Turn on car ignition (don’t start it)
2. Switch hazard lights on.
3. Connect tow electrics plug to car tow electrics socket
Voila! Lights will go through a sequence of:
lights on, hazards, brakes, reverse, fog, pause, and repeat 3 times.

I got my loom from PF. jones, Land Rover specific.

(Anyone know how to enable this on a Range Rover sport 2014, I’ve now swapped to. It apparently has it according to the handbook…
