How to Get the Actual Mileage on a 93-95 850 Volvo
From the following website:

As long as you have the DTC boxes up under the hood ('93-'95).
1. Switch ignition on
2. Connect the fly wire to socket - A7
3. Push button 5 times
4. When LED comes on and stays on, enter code 1-1-1 as follows:
- press the button once when LED is still on
- wait for LED to go out and come on again
- press the button once when LED is still on
- wait for LED to go out and come on again
- press the button once when LED is still on
- read off response, which will be the last three digits of the odometer miles
5. Repeat steps #3-4, but enter code 1-1-2 (that is, press the button twice on the last step); read off the response, which will be the first three digits of the odometer miles. If you have less than 100,000 miles, the first digit will read as 10 blinks.

Try to change your cadence (either speed up or slow down the amount of time you hold the button down and how long you wait between button pushes). After the 5th press the led should come on solid which tell you it is ready to receive a command.
I use about 1 second between each button push with a duty cycle of about 50%.

This is going to be a stupid question but my 850s odometer was broken when I got it (go figure) and to get it through inspection I had to get a used working odometer (makes no sense the real milage is in the computer) but does having a different odometer in my car effect the computers readout? I say this with the thought the there is some chance that the mechanical odometer might linked with the computer.

That's a good question? I would think the speedo head electronically feeds the computer wbether or not the odo is broken. I would also think the communication is only one way ( to the computer). So if that is true then it would make no diff. The "new" speedo head will only add to the computer mileage. Does anybody out there know for sure?
