Hi, my towing lights on my outlander have stopped working. My car is a 2019 Outlander rang the dealer on where the fuse would be but they didn’t ring me back . Does anyone know what fuse it is and if it’s in the engine bay or inside the car? . I have read the manual but can’t work out which one it’s under .

Cheers

Can't speak for the Outlander but most cars would have a fuse for each circuits i.e. tail/turn/stop so if they are all not working more likely to be a plug issue or problem with the trailer earth.

Bugger was hoping just a fuse, the rest of the lights are working on the car , just when I connected the bike rack today the rack lights were not working. Tested the rack on another car it worked ok so issue with mine. We are away camping not far to come home with it not working

Assuming a flat trailer plug, check the plug pins. Often the 2 sides of the pin compress together which can be fixed by spreading them slightly with a small screwdriver blade.

with all lights out, i would be checking the earth. cheap way is to earth the lights to the rack so it earths through the tow bar itself. better if they used the earth through the plug. plug connections are typically no1 fault.

otherwise i would suspect it might have a canbus converter which has died.

Failed earth is pretty likely.

Found a video of the installation of the plug, though that's for a US market. No obvious canbus body module in the rear - usually they're right on the harness/connector there.

There seem to be separate indicator/brake fuses so probably not a single trailer fuse.

Check the internal [inside car; probably on/near the dash somewhere] fusebox for a fuse-tap; I've seen lighting harnesses taking supplementary power that way before; the one I looked at recently had a fuse on the fuse-tap and what looked like an additional inline fuse socket too... Fairly obvious 'extra wire' when you open the cover to the fuses...

The internal fuses on a RHD Outlander are behind the glovebox. There aren't any obvious fuses for tail lights apparently they are fed from ETACS unit but as said if tail lights are working unlikely to involve more than trailer plug/earthing of. I would be surprised if trailer plug wiring extended any further into car than it needed to. Certainly not as far as the fuse box. On our car (not Mitsubishi) the trailer plug connects to car loom behind panel at rear of boot.

This almost certainly has a trailer light interface installed. It will take a single power feed to run all the trailer lights based on sense feeds from the various lights. I expect it is installed behind the plastic covers somewhere at the rear of the car and may well have a fuse close to it, or the interface has failed. If it hasn't been properly installed it may have stolen voltage from the boot light circuit to provide power and the fuse for that may have blown - does the boot light (and other interior lights) work? if not, try replacing the relevant fuse for that circuit.

Interesting they have a fuse in that example, might have a peek when back from holiday , thanks for posting

Thank you all so much for your help. I went down to the local dealership but they couldn’t work it out unless tracing the wires. I went and got a new battery on the way home as it’s been not charging well. When I went to swap out the battery i found the fuse . Swapped it out everything now works.
