On my 1992 cadillac eldorado,where is the memory for the odometer stored?

Is it on a computer module or is it actually in the cluster? Please let me know , If you know the answer.On my 1992 cadillac eldorado,where is the memory for the odometer stored?LUSTER, Digital - There are two different designs. In ‘87 Digital was the only available unit, ‘88 - ‘93 digital was std %26amp; analog optional. Digital ‘87 to ‘89 is the same part #, ‘90 to ‘93 will not work on the older models. The PROM in the BCM retains the total original mileage for a car. The digital cluster will display what the BCM computer tells it to display from memory.



CLUSTER, Analog - There are three “different” designs.. 1987's did not come from the factory with an analog cluster. 1988' and 89's used the same analog cluster, which will fit 1987's just fine. 1990 through 1992 used the same analog cluster, which is different from the ‘88/’89 unit. Lastly, 1993 analog clusters are unique to 1993 Allante's, and they are different from all earlier models. The analog cluster has a mechanical odometer, which advances with the car's forward motion, and has no way of going back other than mechanical tampering. The analog ignores the PROM in the BCM which continues to retains the total original mileage for a car in memory. There are different part numbers for the different clusters. That's the easiest way to tell. But beyond that, the '93 analog is easy to ID since the tach range is higher than for the earlier models. The way to tell the earlier two models apart is through the warning lights section. The 1988/89 does not have traction control or air bag warning light like the 1990/92 analog.



CLUSTER, compatibility - The analog and digital clusters for 1993 fit 1993 ONLY. The analog and digital clusters for 1990 through 1992 fit ‘90-‘92 ONLY. 1987 digital cluster will fit 1987 through 1989. ‘88/’89 digital clusters will fit ‘87 through ‘89. The ‘88/’89 analog clusters will fit ‘87 through ‘89. Nothing is backward or forward compatible outside of these groupings.
