Thread: D4 Electric Trailer Brake Wiring

G'day Sneigy

I'm still at it. The fuses are Ok. Yeah, I'm aware of what the diode is doing. (ex sparkie)

I will give the Installer in Canberra a call on Monday about me fitting the diode. I'm not sure of the consequences re: warranty if I start to change things.

To be honest ,I think I am more clued up than them now, considering the problems I've had since this install. Anyway I'll see what they have to say then.

I'm going to try a few things over the Weekend. I'm just going through
trying to elliminate things as I go.

I live in the Snowy Mountains, Talbingo.

Thanks again Pete & Graeme

Cooling my heels today whilst there's a ban on harvesting.

Call in if you're in the area mate. Just follow the golf course all the way up & you run into my Driveway.

Bring beer.

G'day guys

Just to keep you updated on my little Trailer brake Saga.

I had the D4 booked in at Lennocks LR (Canberra) today for A 52K service & asked if they would look at the "no trailer brake signal" problem that I've been annoying everyone with.

At this stage the rear parking sensors had also taken their bat & ball & gone home.

Also,yesterday the engine warning light had come on

I could not believe all this was happening to my poor D4. It seemed like it was slowly turning it's toes(wheels) up.

Anyway when I went in to pick the car up, the Service Guy said they had found a hard short circuit on the brake signal pickup wire to the EBC. He went on to say that I would have to go & see the original people who did the Installation to fix it.

I got talking to the Technician that worked on my D4 (@ Lennocks) & asked him to cut this shorted wire, which he did.

Presto!!!! The Body Module Computer (BMP) then restored power back to the Brake light signal wire at the Trailer socket.

The rear parking sensors decided to play the game again also.

To say that I was one happy chappie was an understatement I can tell you.

So the upshot @ the moment is that I have decided not to go back to the original installers. They have had their time at it & failed twice.

I am going to give the job to Lennocks LR as the Technician that worked on my D4 was very clued up about the Hows & Why's.

One interesting point I found out, was that Lennocks LR used to have the mob I went to, to do their ECB installs. The last 3 installs they had done all had problems. Lennocks LR do their own installs now.

I wish I had known this before hand. Would have saved a lot of travelling & Heartache!

So that is where I am at now. A whole lot happier that I'm not up for a $2500 computer.

I'll let you kmow how it went when the rewire is completed.

Thanks again Guys for your help

If they found what the issue was, why didnt they just fix it

Lennock's did not do the original Trailer EBC install. The D4 was primararly in there for a service.

They were trying to find why the Trailer stop light cicuit & reversing sensors were not working.

They did not see it as their job at that stage, to work on the other mob's stuff up. I can understand that.

Hopefully all the wiring problems will be solved later this week

They didn't want to void the ebc instal warranty?

And spend his money

Hi everyone.
Picking up a D4 at the end of the week for my wife. The D4 will come in handy when I want to tow my boat. That must be a win win situation. Never had a land rover before. I have to wire up a brake controller for the D4 and found this informative forum.
Thanks
