No way to tell without taking it apart.
The odometer on a 96 Ford Explorer is tied into the speedometer. If the speedometer is working then there is a gear problem inside of the speedometer causing the odometer to not work.
Sounds like the speedometer cable broke.
The logical problem - would be a broken speedo cable. The speedo & odometer are both run from the same cable.
If the speedometer doesn't work either, then the cable broke or came loose. Otherwise, the gears in the odometer broke.
Check the fuse in the fuse box; Also check to see if your speedometer cable snapped, this will cause the odometer to stop working as well If your speedometer is still working and just the odometer has stopped, the most likely problem is a little plastic drive gear in the instrument cluster. This is the most common problem with many makes of cars. If you are handy you can buy a replacement gear on Ebay for a few dollars and replace it yourself. Otherwise take the vehicle to an instrument repair shop. This problem usually occurs if you reset your odometer while travelling, it breaks a tooth off the little gear.

If the speedometer continues to work - probably a broken gear etc. in speedometer head and probably will have to be replaced. If speedometer does not work -- probably a broken speedometer cable

There are a few reasons that could cause the speedometer to stop working on your Toyota Camry. If the mileage is still working then the speedometer cable end is damaged. If both the odometer and speedometer do not work then the cable is most likely broken.
check speedometer cable for possible disconnection; it comes out of firewall and goes to transmission
