S-AWC Service Required Light

I wouldn't brush it off these pumps are a bit pricy mine just went out had 36k miles on the car the pump itself was 1,700$ it was covered under my extended warranty I would advise taking it in and not chancing it

30 000 miles on the car, it was parked for some days, during these days it started to snow, temp was around -10 Celsius....
At first start, I let the engine warm up properly, put it it "snow" mode, drove around 1 mile and on the first corner the "service required" and diff icon light came up
It was the first drive with summer tires on snow, I still hope that it somehow noticed it slips like crazy and this caused the error? Please someone say that might be the cause
But later with light coming on after ignition, I took a "U" turn and I thought I will never make it huge under-steer.
If the $2000 pump burn out just because car was left outside in the snow, then I will buy a Lada Niva and have fun with that, many of them are actually cheaper than this Mitsu pump anyway
Edit: it wasn't the tires, I installed the winter ones. Must be the pump, I will scan it.

its a common problem on these cars fot the ayc pump to rust up and then not be able to build up pressure
most of the time its not a failure of the pump if you can hear the pump spinning and not stopping until after 7 secounds you no you have this problem
the ayc pump should start spinning build up presure and then slow down, if your pump runs at the same speed after starting up for 7 secounds its probably the cause
if you live in a area with cold weather and salt on the roads, u will encounter this problem for sure
good thing is you can get them rebuilt for alot less than a new one, mine came to £300 rebuilt, where dealers wanted £2000+ for new one

the ayc pump is fitted behind the drivers side rear wheel behind the rear bumper, direclty behind the rear wheel, plactic arch liner, low down
if your sat in the car trying to listen for it, you might not hear it unless you no what your listening for
the best thing to is postion yourself crouched down behind the rear wheel area on drivers side next to the rear bumper
have someone else just start the car, and let it tick over your listening for a pump to start up and pump up pressure then slow down, if its spinning the same speed the car will shut it down after 7 secounds and there will be most likely a fault with the pressure the pump produces for the ayc awc sysytem etc
your listening for a pump to start, build up pressure, then slow down , stop, all within 3-5 secounds, if its the same speed and your timining it to around 7 secounds, its most likely a pump failure, if you can not hear the pump like you said there could be a fault with the electircs powering the pump
you will be very suprized how much crap builds up around these pumps, try to have a look if its covered in dirt and clean it off sparay lots of grease around it to

We had rear bumper damage and the pump was part of the repair.

sorry forgot to mention drivers side is right hand side of car here
the pump only starts on starting up the car, its different to a fuel pump that might start with ignition on, 100% sure it only spins up on starting up the car(engine running)
