Indicator Problems

[paulfr]

Obviously you have tred disconnecting the battery for a minute or so?

Yes,tried that.I'm lost at the moment!

 

[Robert]

So i checked the fuses today and both seem ok,contacted traven lite and they are going to send me a couple of resistors to put on.........hopeing that fixes the problem or there will be a couple of LED Headlights coming up on the for sale thread....Can't let the van stand in this sunny weather!

Connecting any resistors won't fix your problem.
Your BCM is missing one supply and this needs to be addressed.

 

[paulfr]

Been out again to check the fuses and replaced them just in case but still the hazard lights seem normal in the van(but not working) and the indicators very quick(but not working!

 

[Robert]

Do your brake lights work?

 

[paulfr]

yes they are fine!

 

[Robert]

What exactly have you done to your van recently?
Please list all.

 

[paulfr]

Fitted the OEM led back lights,then the led side repeaters...all fine...then the led headlights worked ok,but then the battery died and had to recharge and now nothing from the indicators or hazzards.Everything apart from the indicators and Hazzards work fine.

What’s up with missing trailer module
Do you have a towbar fitted ? Has it been removed ?

 

[paulfr]

No towbar,but it is an ex AA van and did have a tow bar before conversion.

 

[paulfr]

Thinking i could have blown a fuse from jumps to the battery?

 

[paulfr]

Took the new front lights out and put the old ones back in,but still the same faults and no hazzards/indicators......any ideas?

I am with the same problem, have you been able to solve it?

No,still none the wiser.

Just been out and someone had put the fuse sc47 into the wrong hole.Working now,but they seem a bit fast inside,but ok outside

 

[Robert]

Access BCM plugs by following this video.

And measure voltage on Pin number 13 on BCM plug B (white one).

Just curious - is the double flash with indicators only, or also with hazard?
======================

the led side repeaters..

You are correct mate, you have to add resistor to fix indicator double flash.
Something like this(6Ω, 12V, 50W) connected in parallel before the tail light plug will do

To measure power consumption of any bulb the best thing would be to use adjustable power supply unit with output current & voltage display and your power is ( P = I × U).
If you don't have such a device than you could measure your new bulb resistance( using ohmmeter although not easy in some cases).
Once you have your resistance value, the power would be (P = U² ÷ R).

But you have to be also aware that vehicle voltage is 12V when engine is OFF and it rises to 14.5V when engine is ON.
So even if you do your maths 100% correctly for 12V it may not be accurate enough for 14.5V.
There is some tolerance from the BCM perspective but I have never verified how much that tolerance is (% of expected watts being consumed).

In your case, as a indicative guidance only, cause it is based on some assumptions ( approx. 2.5W for side repeater)
I would suggest to use 3.3 ohm(at least 100W) resistor connected in parallel to any bulb.

======================

So just taken it for a run and indicators are working perfectly now,maybe a lowish battery?

 

[Robert]

Double flash doesn't apply to hazard lights.
They always flash at the same rate (inside & outside) regardless if there is faulty bulb or not.

I know this is an old thread but just in case anyone looks this up in future as I did, I’ve had this problem for a few weeks and thought I had it down when I started metering through the rear o/S light cluster and couldn’t get power to the scotch lock for the trailer electrics. To make it easier to swing through I disconnected the trailer tap in and rejoined the original wire straight through. This solved the problem. Turns out the problem was with the tow bar electrics. Something worth trying if your T6 has a tow bar fitted.
