Just got my first "service 4-wd" message on my DIC today. The message appeared after I re-started engine following being shut down for 5 minutes or so. I have reset but still comes back on immediately after re-starting. I drove down the road a couple of miles, pulled over and pressed the button to engage 4-WD High. Appeard to go in OK. Tried 4-WD Lo and I was unable for some time to get it to go back to 2-WD high. Thought I was going to have to ride in for several miles under 45 mph or call a tow.
I have read several posts suggesting this may a faulty 4-WD electronic switch. Truck only has 2,500 miles, 2005 model D-Max. Any suggestions before I head to the Dealership. The GM Dealership in my town is not noted for having the best diagnostics. Had to get the fix for my 1995, 6.5 PMD problem from a diesel troubleshooting website, so you can see why I have little faith in their ability. Any Tech help would be greatly appreciated.
Thanks.
