Odometer/Computer Question

[etc]

Does the onboard computer keep track of how many miles are on the truck? My odometer died a few years ago(I gotta tear the dash apart to see if it's just loose since it comes on every now and then for a few miles), So my oil changes have been every three months. I'd like to know how many miles I've put on it.


Anyone know where the comptuer keeps track or not?

I'm pretty sure that only the odometer tracks mileage....i don't think that our trucks, at least earlier model-year, have the capability to change the analog reading from the speedo/cable to a digital reading that the ecu would read & retain...
