Default Odometer Question

I guess my odometer has not been working for about 30,000 miles. When I fix that, will the mileage correct itself of will it stay at where it is at? Should I just get the correct mileage from the computer and change the mileage on the odometer myself? This is a 94, so I believe I can get the mileage with out using a scan tool, am I correct?

Thanks for the help.

The odometer reading will just advance from where it was when it broke, it doesn't reset itself. You can pull the mileage from port A-7 and correct the mileage after you replace the gears. I chucked up a pencil into a battery drill to correct mine.

I did the same thing recently. My odometer broke in December and estimated that I went about 6k miles (I drive a lot) so I did what Ozark Lee did and used the pencil in a drill technique to roll it. Took about 20 minutes to roll 6k, I can't imagine how long 30k will take though

On a related topic, how do I pull the correct mileage from A7? I assume there is a sequence to use on the button?? Would like to know how far off I really am.

Flywire to port A-7. Press the button 5 times briefly but firmly. The LED should light solid.

Enter 1-1-1 with the button and the LED will respond with the first 3 digits of the stored mileage.

Repeat and enter code 1-1-2 and the LED will read out the last three digits of the stored mileage.

If any of the numbers is a zero it will read out as 10 rapid flashes.

I think on 96 and 97 you have to get the mileage thru the OBD2 port. Some OBD2 computers can give u the mileage, otherwise the stealership can pull it!

If you are careful you can remove the motor assembly from the odometer gears and spring open and adjust the mileage.
