OK, so lately my 2007 H3 has been killing me with messages.... Service 4wd, And Service Stab System... Now Trac System idiot light is on too.... Its got 130,000 miles and actually runs just fine besides the messages and lights (and exhaust leak due to broken exhaust manifold bolts). I tried it in 4 high and low today and it worked reasonably well. i.e. shifted into and out of those modes as usual. where do i start to look into these issues. Any help would be awesome.

 

when was the last time you changed the fluid??

 

Hello, try checking your wheel bearings in front.

 

I was getting Serv 4WD message too. It would just come on periodically and then go back off in a few minutes. Once when it came on, I got off the interstate at an exit, pulled to the side and cycled through the buttons. Then I put it in 4LO and let it roll down the side of the exit for about 50 yards. Whether or not it actually did anything that helped or not, the light has not come back on in the past few weeks. It was doing it fairly regularly.

 

Well, not sure really. Look it up on here with search, never know maybe it is a sensor or something.

 

Service stability light will generate a code in computer, go the advance autoparts and ask them to read abs code and you can start from there. Just remember the abs system is tied into other notifications and when pulling codes on any vehicle you always fix the first code that shows up and they will appear in the lowest order on reader
