no, your VX was working properly before
TOD works like this in 4Hi (normal driving)
at rest only rear tires should be illuminated
up to 5mph only rear tires illuminated
at 5mph 1st bar of front tires should illuminate, indicating 15% power to front wheels, 85% to the rear, this is normal driving conditions
if the rear wheels slip mildly or you give 100% throttle, 2nd light should illuminate indicating 35% power to the front wheels 65% to the rear
if the rear wheels are on ice or something, all three front bars should illuminate indicating 50% power to the front and 50% to the rear
cruising at highway speeds on dry pavement you should always have 15% power to the front
