nurkvinny Posted July 31, 2015 Report Share Posted July 31, 2015 03 crew cab 1500HD 4wd, 6.0L. Over the past few weeks, the service airbag message has came on and stayed on, the 4wd selector switch thinks I'm in 4wd low, and now this morning, the anti lock system tries to kick in during every stop, even going slowly on dry pavement. All related? Ideas? I know... get it scanned. Quote Link to comment Share on other sites More sharing options...
Rocky31186 Posted July 31, 2015 Report Share Posted July 31, 2015 We have had issues with our 2500's doing funky stuff because of the ground by the body mount under the drivers feet area. Abs / 4wd issues. Check to see if that ground is still connected / tight and free of corrosion. Quote Link to comment Share on other sites More sharing options...

aussiek2000 Posted July 31, 2015 Report Share Posted July 31, 2015 front hubs are the usual culprit for ABS kicking on. Air bag could be anything. seen lots of 4wd issues when mice get into fuse box and either piss all over it, or chew up wires Quote Link to comment Share on other sites More sharing options...
Cordell Posted July 31, 2015 Report Share Posted July 31, 2015 Pull up the underhood fuseblock and make sure there isn't rodent damage, they love that spot. Likely needs one of the hubs,and one of the front impact sensors. That stuff is common, 4wd could be a switch or an encoder motor if it isn't wiring. Thats the stuff that seems most typical. Otherwise you should get it scanned. Quote Link to comment Share on other sites More sharing options...
nurkvinny Posted July 31, 2015 Author Report Share Posted July 31, 2015 Grounds mentioned above cleaned. Yellow 4wd harness inspected and looks ok. No sign of rodents. Battery undone, terminals cleaned. We shall see. Quote Link to comment Share on other sites More sharing options...
nurkvinny Posted August 4, 2015 Author Report Share Posted August 4, 2015 Up first... B0100 GM SRS, short in D squib circuit. Front impact sensor ? Quote Link to comment Share on other sites More sharing options...
aussiek2000 Posted August 4, 2015 Report Share Posted August 4, 2015 9 times out of 10 its the sensor. trucks are bad about corroding where bolt goes through the sensor. and then the corrosion splits the sensor apart Quote Link to comment Share on other sites More sharing options...

nurkvinny Posted August 5, 2015 Author Report Share Posted August 5, 2015 Is this an undo battery for a few minutes then replace sensor, or am I really at risk of firing off a big powdery balloon? Quote Link to comment Share on other sites More sharing options...
Cordell Posted August 5, 2015 Report Share Posted August 5, 2015 Is this an undo battery for a few minutes then replace sensor, or am I really at risk of firing off a big powdery balloon? Supposed to, but I never do. GM airbags typically aren't sensitive enough to a quick plug unplug. You may want to play it safe. In other words, don't disconnect the battery at your own risk.

nurkvinny Posted August 6, 2015 Author Report Share Posted August 6, 2015 So if I undo battery, have a slow beer, then crawl under there and swap sensors, I'm good? Next up... encoder motor. Quote Link to comment Share on other sites More sharing options...
NHRATA Posted August 6, 2015 Report Share Posted August 6, 2015 I can scan it for you Quote Link to comment Share on other sites More sharing options...
Cordell Posted August 6, 2015 Report Share Posted August 6, 2015 So if I undo battery, have a slow beer, then crawl under there and swap sensors, I'm good? Next up... encoder motor. Pretty much. Are you sure it's encoder motor? It's common but not the only thing that goes bad. Quote Link to comment Share on other sites More sharing options...
