TPWS

After changing to my winter wheels and tires, I have been unable to get the light off and the TPWS to register correctly. I have had the sensors checked and the technician said I just have to drive the vehicle to WAKE the sensors up. I have driven about 150 miles with the light on and the screen indicating the computer was registering the sensors.Tire pressure is correct but I think the computer is stuck in the registering mode. I can stop and turn the vehicle off for hours and overnight but when I start it and drive the next time the light flashes 3 long flashes and then goes solid and the screen indicates it is registering the sensors again. Is there some way to reboot the computer short of removing the battery cable. This is the 2nd year I have used these wheels and sensors and I did not have this problem before.
