TOD Malfunction ?

[AndyC]

Wow I was returning from Portmouth, NH today and had the TOD mess up too but it would go in and out of Check. I pulled over several times to check it but had no idea on what it could be. I never thought of the snow/ice buildup in the rims. I was stumped as I got closer to home and the system seemed fine. I washed all the snow and salt/sand off and put it back in the garage. It was a late night and I beat. Now I check the site and what are the first 3 post TOD problems -- go figure. I did lock it into 4 low and it worked fine so I'm happy to hope/figure it was just the ice/slush in the rims.
Hopefully that was it I'll fine out tomorrow.

Driving throught the blizzard in Boston, my TOD goes to all lights blazing and then the TOD check light appears.
When I slow to a stop, the lights descend, but the check light keeps flashing and then as I acclerate I engage all wheels again.
Come to a stop, turn off the engine, restart and no TOD warning light.
