I just switched the bumper on my 2013 Chevy Silverado and I got the service Park assist message going. I drove it without the bumper for a while so that was on because the whole harness was unplugged. Everything’s put back together now and appears to be in good working condition, but I can’t figure out how to reset that message? The system is not working because when it’s in that state it’s disabled. I would like to get it working again if possible.
I’ve tried removing the negative terminal on the battery for 15 minutes.
Pulling the fuse, pulling the negative terminal. Letting it sit for 15 minutes starting the truck back up. Placing the fuse back into place.
I can’t seem to find anywhere that someone’s been able to do the successfully without a scan tool are going to the dealer. I’d like to avoid going to the dealer. I don’t wanna spend a couple hundred dollars to turn the system back on.
