Disclaimer: It is perfectly legal to program an odometer to represent the correct mileage for the car.

The car is a 2006 Nissan Sentra 1.8S. The instrument cluster is faulty and flips overdrive on and off at random. I ruled out the rest (switch, TCM). Thus, the cheapest option is to swap in another cluster, but that means that my mileage will be wrong. The replacement cluster I picked up on Ebay has 24K miles. Mine has 181K. Slight difference there.

Solution Summary:

Use an EZP2013 IC programmer to read the memory from your old cluster and write that to the new one. Clearly this assumes that you are still in possession of your old cluster and that its EEPROM is intact.

Now I am not that into heat, but the idea of a sheet of ice on the windshield with no recourse just doesn't sound like fun.

Since I had to figure out what the issue was step-by-step, I figured I'd write the process down for posterity (read: me, next time). So here it is...
