I've noticed that the car has started to give me all the dummy messages, particlarly "CHECK 4WD" when I turn the ignition on without the engine running. If I then hold the brake pedal and start the engine, the message remains. If I turn the ignition off, and then start normally with the brake pedal depressed and start the engine it goes all normally and "CHECK OK" and I never get any errors when driving. I also noticed when this happens the AFS light is flashing as well - well, basically every warning on the dash is lit.

So, what's up with that ... I know it's normal for all the dash lights to light when the ignition is on and engine is off but I never noticed CHECK 4WD in this state previously. I haven't really noticed if it happens every time but it seems to happen quite a bit when I just turn the ignition back on to do something like close the moonroof if I forgot it. It's also odd that it doesn't clear when starting the car without first turning ignition off after that.

I assume that nothing is actually broken because it all behaves normally when starting the car regularly and the car does not complain at all when driving around. Any ideas?

I am having the same issue..for some reason when I drove off from the gas station yesterday and got to the gym (2 mile distance) my car got a "Check 4wd" light. I have never seen this before. My car is a 2006 GS300 AWD and Im on the stock GS430 wheels...Should I be worried about anything?
