It's a flash for cold weather regions. My understanding is that it doesn't immediately prime the pump until after everything has had a chance to warm up a little. It makes it easier on the motor and pump.

 

Are you guys talking about this reflash?Found via https://www.evolutionm.net/forums/ev...formation.html

After reading the SC linked above, it states "Warranty Coverage: Basic coverage 3 years / 36,000 miles".

Not sure if that's a warranty on the reflash itself (that would seem odd), or what part of your warranty covers the reflash. Anyway, if you're still within your 3-year bumper-to-bumper, just print out the SC and take it to the dealership.

 

^That's great info, thanks! I think there is a newer relfash that came out in March of this year though. The number is SC-11-002. I've not been able to locate the actual document to compare the differences. I'll definitely print this out and take it on when I go. Thanks again.

 

SC-11-002 is the same as and replaces SC-09-002. Slightly different program, but the upshot is the same: delay the activation of the AYC pump until the rear diff has a chance to warm up. If you search the Mitsu database, SC-09-002 isn't listed any more.

 

Unfortunately, I don't have a Mitsu database

So is SC-11-002 100% identical to SC-09-002, covering cars made prior to 8/28/09.. or are there newer cars now being covered??

 

I can't get the text, either, so I can't answer your question. All I've been able to find is that it is an alternative program for delaying the start of the AYC pump. Sorry.

 

i did not pay for my reflash and i have 77xxx miles. i am in central-north jersey and i pretty much took the car in and said my pump is broke and i didn tget the reflash and they did it for me. im way over warranty but they did reflash for free so not sure.

As to the pump i jsut got a new one mine was broken and reflash did nothing but reflash is a must for colder weather it lets the pump warm up before it burns out
