| Trailer socket 13pin RH indicator 12V continuous (no flash)? |
|
Ok here we go!
My D3 05 have new 13pin trailer socket.
RH indicator is showing 12V continuous (green wire) without normal flashing? Why?
LH indicator is normal (yellow wire).
Indicators on the car is ok.
Trailer Fuses in rear compartment OK.
No faults on IDD-tool.
Removed bumper, checked connections and measuered same 12V (green wire) in all related connections in the rear.
My understanding is that there is no separate fuses for trailer indicators.
But there is 12V power so I suspect a relay (no flash) problem.
Is the relay built in the CJB?
Suggestions Anyone?
Thanks!

There is a fet in the cjb for the towbar indicators
Check it’s set correctly with iidd.
There are many options.
Follow the wire into the rear of the car and see what car wire it is.
What happens if you remove both 15a fuses.
Does the 12v go?

Hi Pete! Thanks for input!
I tried different approaches with same result, 11V still..
I really think the FET in the CJB have "locked" itself in ON mode giving 11V without ON/OFF it normally should to provide "blink".
In desperate need of an MOT approval I choose the short route.
Cut the green wire (right indicator trailer) and pigtailed the right indicator behind the rear cluster.
The IDD-tool didnt protest and now the D3 is MOT approved
