You have to remember though, the reprogram actually ensures the AWC is not working at full potential until it gets warmed. Is it really something you'll need in SC ?
This is untrue, you can receive the patch at any nationwide dealership if you VIN # was originally from the eligible VINs in that state (I was told that a guy who originally bought his vehicle in NJ was able to get the patch at the same dealership in CA that i tried to get the patch from). When the dealer plugs the MUT3 into your car and then locates patches specific to your VIN # it will find the patch and apply it. Only cars sold in the eligible states have their VINs available to download the patch. This is the reason i'm filing a complaint to NHTSA since i'm unable to even request this patch from dealerships and mitsu corporate will not work with me on getting my VIN added to the list.

Hey everyone, sorry to bump an old thread, but having some issues with car after having the S-AWC reflash done.

So I got the reflash done at the dealer about a month ago, but I'm still seeing the "Service Required" with the drive train image on the display. When I started up my car this morning, it was about -29C and I didn't see it on my drive to work. Although, I did see the S-AWC setting on the top of the display (ie, Tarmac, Snow, Gravel) kinda disappear and reappear every so often. It wasn't until just an hour ago I went out for lunch that the Service Required message popped up. It was a bit warmer during lunch time (around -20C) than it was this morning, so I'm not too sure why it didn't happen this morning and happened to me during lunch.

I used to have the Cobb AP Stage 1 Stock Intake map running on my car, but I unmarried it, then ran the car for about a week before I brought it into the dealership for the reflash. I loaded back the Stage 1 map about a week after I got the reflash done. I've been reading on here that the reflash does not effect the ECU at all, so I don't think reloading the Stage 1 Map has clobbered any data that the reflash did. I'm going to unmarry my car when I get home from work today to see if that fixes anything.

Anyone else experience this problem or might know what's wrong?

Update: Alright I've unmarried my car with the stock settings, but still getting the same problem. Guess I'll have to call the dealership to see what they say about it.

Are you sure you're not getting the "service required" message because your car actually needs service? What I mean is, the MID has the service mileage/time before service. I'm pretty sure the message "service required" is from that needing to be reset. It's not like the SES light. Maybe I'm wrong, but it's worth a look.

Yeah I'm pretty sure, because the actual scheduled service required message has a picture of a wrench on the MID I believe, and this one has a picture of the drivetrain.

But in any case I emailed the service manager at my dealership and this is what he said:
With this cold weather, the AWC hydralic pump cannot flow the fluid properly to the rear diiff and t-case. The re-flash was to stop the pump from working and burning out. You will recieve this message telling you the S-AWC is not active and defaults to the tarmac setting. This is normal for the cold weather. If the light does continue to stay on when it warms up, please contact me to further diagnos the light.
So I'm happy to hear that it's nothing really major, just stupid Canadian weather causing problems.
