4WD Light

[MasterTech8]

On my way home today my "service 4wd" message came on. Don't know what the problem would be. Please help!

take it by autozone they will run/clear the code

i was doing some reading in a book and it said to shut off the engine and then start it back up and see if the message comes back on. i did so and it stayed off. but does that mean that there is something wrong???

It could be the 4wd switch on your dash. check google

Ok if that is the case then wouldn't the light be flashing??

If the "service 4wd" light came on there should be a code stored in the 4wd component memory. It's really the only way to tell what happened.

By the way, what year, model & engine?

Today at work i pulled the codes that should be in the system and there was none. So i am guessing that is not a problem or if there was then it was a false problem. The Truck is a 2004 Chevy Silverado Z71 with the 5300 vortec engine.

OK that's a good thing. However, if the light comes back on again check it for codes while it's on and active. Hope you're using a scanner that's capable of accessing the 4WD system.
