Truck has been engaging tow/haul mode by itself. I'll hit the button and the tow/haul will disengage, about 10 seconds later the tow/haul mode will engage again, by itself. Seems to do it less when truck is at operating temps, plus it has been warmer here the last couple days (in the 50's) and the truck has only done it once. Last week when it was colder, the truck went into tow/haul mode at least twice driving to and from work. I assumed I had a bad tow/haul botton or a frayed wire in the steering column. A buddy of mine suggested I let a friend scan the OBDII (I am not throwing any codes). Truck got scanned today and it came up "No communication with Transfer Case"!!!??? 4x4 was last used two weeks ago with no problems. I do have lockout hubs, but that should have nothing to do with it. Any ideas??? Are both issued related??
