Thread: D4 Electric Trailer Brake Wiring

Hi I'm a new member and just wanted to say thanks to all those who posted in this thread. It has been a really great help.

I have a new D4 SDV6 3.0 that I intend to get a trailer brake controller fitted in a week or so. Going to use the same guy in the east of Melbourne to do this who put the one into my D3 TDV6 which I have just replaced. I'll post how it goes.

Hopefully it works for you.

I received it, tested it, and while all the lights on the trailer worked, as did the trailer brakes, nothing has come up on the dash so I can only assume that trailer assist does not work.

There is no tell take sign that illuminates on the dash to say that the trailer assist is working.
The only way to tell if the trailer system is working correctly is that the trailer indicator flashes when a trailer is connected & the reverse park sensors do no operate when reverse is selected.

Trailer assist operates with or without a trailer fitted.
It is the oscillation threshold that changes for the system to operate properly as per the brief in the FAQ.

Cheers

I fitted a Tekonsha P3 to my D4 18 months ago following Pete's very helpful and detailed instructions and have not had any problems what-so-ever.

The reversing sensors do not sound when reversing while towing and the trailer symbol flashes on the dash in unison with the blinkers. My Bushtracker van has a combination of LED and incandescent brake lights.

Thanks snugly. I was wondering when this was going to come out. There is also a video clip on the LR website regarding the trailer stability assist that describes it.

Damn auto correct....

That's what my wife calls me :-) I don't know you that well sweetheart ;-)
Hehe!

Sorry, I meant that I can only assume trailer assist is to working as my reverse sensors still work when put into reverse with the camper on!
