Hi All,

I’ve done some searching but nothing seems to quite match my issue. I’ve got trailer light issues, tail lights and brake lights ( only) when connecting to the Rangie.

for context I fitted a RedArc Tow Pro a while ago for when I tow my caravan with electric brakes.

The tail lights and brake lights seem to work intermittently on the trailer. I built a Resistor Module in case it was something to do with circuit load (as I had done with the caravan) but didn’t fix it.

I’ve double checked everything twice and can’t find any loose wires or bad connections.

i can’t find the exact info about the Lighting Control Module but the wire from the LCM going into the Trailer Control Module had 0v on it and hence 0v on the wire out of the TCM ….and onto the trailer.
I haven’t tested the brake scenario but assume it is the same, ie 0v from the LCM going into the TCM.

All the vehicle lights work correctly.

Before writing more info, I was just wondering if anybody has had similar issues and how they fixed it ?

I’ve read about some LCM issues faults but not like this
