I just bought a used 2001 Suburban with 40K miles on it. After owning it a
day or two the SERVICE 4WD light comes on the message center. It goes away
after I turn the ignition off, but will come back after a while. It has
come back two times now and I've only owned it a few days.
I read on another board that it could be a bad transfer case switch. Any

Yes, what history code is stored in the ATC section?
If it's 2725, then the problem is in t/case dash switch.

That will be hard to know unless you diagnose the
problem properly and know what component needs
to be replaced. Then you can call your warranty
company and find out if "that" component is covered.
A lot will depend on what kind of coverage you have.
The dealership has a 30-day warranty that will cover 15% parts and labor. I
also bought a 1-year extended warranty although I don't really know what
this covers. I'll probably find out in the next couple days. I won't be
afraid to cancel the warranty if it doesn't work out in this case.
Yes, the specific transfer cases that happen to be in the
Bravada, Trailblazer, Envoy vehicles. Have a look thru
your SI2000 and see if you can find that bulletin for the
2001 Suburban that the OP was talking about. You won't
find it, because the sensor replacement you are talking
about doesn't apply to a 2001 Suburban. In addition to
that, he was complaining about the "service 4X4" light
coming on. The condition you refer to will not set a
The GMT 360/370 models use either a 126 or 226
model t/case. The C/K 800 trucks (suburban) use
either the 263 or 236/246 t-cases.....different beasts
Pull the dash switch and go over it very closely, I bet it will be the
problem, I have seen too many with this problem. There is no need to replace
the switch if you have any solder skills, I have done a few now and they
take the greater part of fifteen minutes to remove and fix and reinstall.
I had this happen to me about 3 weeks ago and it turned out to be the 4WD
Selector Switch which was covered under my extended warranty. However, I
have a $100 deductible and the bill came to $117 so....it cost me the $100.

That's my exact situation. I have a $100 extended warranty deductible as
well. I'm getting it diagnosed tomorrow... we'll see if it's the selector
switch. Based on everything I've read it seems like the likely culprit.
Thanks to all who chimed in on this thread. I took the truck back to the
dealership and it indeed turned out to be the transfer case switch (code
2725). Since I bought it used from the dealership a week ago they replaced
it for free. Imagine my surprise!
