How do I use the instrument cluster test modes to reset the miles light indicating the odometer was replaced? (I have the dash with 21 or 22 built in test functions). I know this is possible, I just can't find documentation on how to do it. I think it is test 17 or 18, but I don't know what I do when I get to that test.

There are two computers in the car that store the odometer reading, if one is less than the other it will indicate a fault, and it is possible to copy the higher mileage one into the lower mileage one (so just the higher mileage one remains) and the light will go off. I have been able to get it to do this, but only on a temporary basis. The light comes back on when I unplug the battery. Is this how it is supposed to work so someone couldn't cover up that they replace the odometer?
