2021 Defender 110 L663 trailer electrics problem
I have a LR fitted detachable tow bar (UK) and all the trailer lighting has stopped working. It has a European 13-pin electric socket and I have been successfully using a 13-7pin adaptor on 3 different small trailers for a year and now none of the trailer lights work and the trailer symbol does not appear on the dash or the show towing as an option in cameras. I can measure 12v+ voltage on the permanent live pin and its earth but no voltage to be found on any other pins. I have checked and tested the only fuse related to the Towbar and I can’t see a way of fault finding an rectifying the issue. I have successfully tested all the trailers.

Today I hooked up a brand-new caravan with 13-pin electrics, the caravan's powered stabilizer activated - but no brake/turn/other lights work.

Any help or advice gratefully received.

Is there any option in the menu related to towing?

If you don’t have the menu option, sounds like the cars forgotten the towing option or the module has failed.

If a hard reset doesn’t fix it, then a dealer trip.

If it’s mission critical call lr assist Mike

Thanks for the reply. I will contact the dealer for the 4th time today. I hope they can understand.

All fixed by dealer, you were correct - Apparently the tow module/controller had dropped out of the car’s software/settings and had to be reinstalled. At least it was covered by the warranty but who knows if it will mysteriously disappear again? Fingers crossed.
