Hi guys, new to the forum.
I just purchased my first jimny, a 2012 model with 220.000 km under the hood.
its a bit of a lemon, but I really like it anyway.
im having a few problems with it but the most serious one is that the 4wd is engaging on its own.
this happens mostly when I turn the ignition key, dont need to start the car, maybe every other time.
its also happened while driving slowly and turning, only once though.
ive also had the relays go berserk and the 4wd lights start blinking, this happens a few seconds after starting the car.

after the 4wd engages I can simply press the 2wd button and it disengages without any problem. the 4wd and 4wd-lo buttons both seem to work fine and do what they should.

I´m thinking maybe one of the three end stop switches might be flimsy?
or simply something wrong with the 4wd controller, a new one is north of 500$ here, so it would be nice to eliminate everything else firs.
or should I simply get manual hubs?

I only seem to be able to find one post on a similar issue and it does not seem to get resolved there.
The suzuki dealership in iceland said they had never heard of anything like this happening.

hope im not the only one

Welcome to the forum. Sounds like either a connection has gone bad or got water in it or that there is a loose or broken wire somewhere. I would suggest the transfer box connection first as it is the most exposed but unless it's a obviously broken wire you're in for a session probing it with a multimeter.

I am more convinced that is a loose or broken connection or wire. Somewhere.
