Ok I see interesting, well unplugging the switch would likely cause a error code, since that same switch is related to 4wd.I’ll try unplugging the TCCM this week and see if the message returns.
As for my stereo I should have clarified what happened. I had to unplug the 4wd buttons, emergency flasher, and traction control button to remove the center trim panel and gain access to the stereo.
I wired up the stereo and was testing everything while the 4wd buttons, emergency flasher, and traction control button was unplugged. The SERV 4wd message displayed but went off after I plugged everything back in. I suspect the message came from unplugging the 4wd buttons because I can’t imagine the flashers or traction control button caused the warning. 🤷🏻♂️
