So yesterday on a little road trip I noticed when I turned my car on I got this warning message “communication module activation failed”. I didn’t pay it any mind and thought that I was in a crappy service area with no bars so it might be telling me that I might be limited on data related stuff. Welp, it started happening every time I started my car after that. I did a bit of googling and saw the “fix” was to disconnect the negative terminal for about 30 minutes and that should resolve the issue. Well after a 1/2 second of popping the hood and realizing the battery is in the back I disconnected the battery. I’ll post an update to let everyone know if this helps in the GRC, all the other posts were about RAVs, Venzas and Siennas.
