Thread: Towing Electrics - Big Tick

If I have the parkers or driving lights on, the trailer lights up, the brake lights works, but when I use the indicators....both indicators flash on the trailer....but dash light does not show a trailer is connected.

How does that compare with before the s/w update?

Hi All,
Just hooked up my box trailer with LED lights to my new MY14 D4 and it does not appear to recognize it, no trailer symbol when indicating and reverse sensors remains active. I might shoot an email to the dealer and ask them what they think should occur. My Jayco has normal lights so that should be OK but I need to arrange a EBC before I tow that.

Andy,
Let me know if you experience anything different to this.

Thanks all.

Philippe.
Just tried mine.
Same result as you.
It seems we do need a load sensor on the MY14 D4.
I asked the question on delivery,salesman wasnt sure,he asked the service manager and he said not required.

I had the LED trailer module installed pre delivery, with a nice little switch to turn on and off as required.

Remember the d 4 sends the pulse upon driver door closing (I think it's close only) so you need to plug in trailer then open & close driver door - I think with the d4 you only 1 of those 21w resistor things wired in parallel between an (1) indicator & the earth - but trailer icon flashes on side of resistor - do a search and there are blokes who have posted about doing it this way
