my wife’s 05 Tahoe started acting up by showing “service 4wd” on the way to church - then on the way to taking the kids to school this morning it showed “stability sys disabled.” I have read some other forms and they are all over the place on what to do or where to start. what they are saying is true — the car acts sluggish and seemed like it switched into 4wd.
looking for any help on where to start?? a sensor ?? some said the encoder motor?? even the 4wd on the dash being replaced??

any ideas would be appreciated & thank you

You start by getting the codes read and not touching the vehicle before that is done.


#3

Are the codes saved?? I could have autozone try to run the codes for me but the problem doesn’t show all the time?


#4

Yes, codes are saved. Go to Auto Zone. Be sure to write down exact letter/digits of code, like P0123.

@JasonM

Don’t be too disappointed if AutoZone can’t read the codes

Not all of those cheapo code readers do ABS

Just giving you a heads up

@db4690 - thanks for the heads up - I plan on taking it this weekend to see what they say - first chance I got!!
If no luck - any other suggestions besides the dealer…

This guy fixed his identical problem by replacing the encoder motor:
