Ok so I know this topic has been discussed here multiple times as I’ve looked at a bunch of the threads but I wanted to start a new thread in hopes of getting a definitive answer quickly. Here goes.
I drive a 2011 auto Pro4X. So 4wd with rest e locker. And everything is currently fully functional with no apparent issues. I hit a big bump a few days ago which immediately activated the abs, brake, vdc and slip lights. But vehicle still apparently drove fine at that point. (Admittedly I did not attempt to activate 4wd or test abs with brake slam method at that point, just regular driving.) Ok, weird I figured but maybe a fluke. So I stopped, shut her down, waited 5 seconds and cranked her back up. All lights off and I went about my business. Then day after I hit another bump and same thing happened. Shut her down and started again but lights persisted. Shut down for longer then started and lights were off. Then an hour or two after lights came on again on their own, without hitting any big bumps or anything. Then went off after next shut down/start. She still drove fine during all this. And lights haven’t been back on. So questions are...
What system exactly is causing this, abs? I think abs based on most everyones’ input so far that abs sensor is generally to blame. Just want to verify that it is only abs system that would shut all of those other systems down. If not what else controls all that?
Unless I broke a sensor or tore a cable what would cause a big bump to trigger that? Uneven tire spin in the moment? Impact just causes sensors to go wonky?
Could dirt/dust/debris interfere with the system at all? I was driving in really gravelly/rocky, dusty uneven roads in Tennessee but nothing crazy. But I’d like to imagine that any truck worth it’s salt should be able to be in off road type environments without shutting systems down.
That pretty much sums it up. Hoping to get some input from those way more knowledgeable than myself on this to see if I’m missing something, should be inspecting something etc. As of now the lights are off and have stayed off. Still haven’t tested 4wd or abs yet but I’m putting money on them being ok as they were ok prior to big bump that initially caused light activation. Thanks ahead of time to anyone who can help.
