Why did this happen?

I only have a basic knowledge of how the wheel sensors work, but enough that I suspected that they should be able to detect wheel direction as well. I spent a few minutes searching and found that there are a couple companies that make directional wheel sensors for automobile manufacturers. They are essentially a normal wheel sensor, but the magnets on the inside of the sensor are staggered with their north and south poles reversed. Then, the outside of the sensor has two magnets, and simple electronics calculate the wheel direction based on what pole is encountered first and by what magnet as it circles the hub.

I called AM General to inquire what model of wheel sensor they use in the H2 and if it is capable of detecting wheel direction. They are supposed to call me back today or tomorrow.
