Update: I had to clear a code on the A2 socket before reading again. The ECU now reads 168,808 miles and I have 168,817 on the odometer, that's close enough! :)

Is there any way to get the actual mileage from an OBD-II ECU? I have a '96 850 base model, and the odometer's stuck at 51,723. I just got stuck with a 'not actual' branded title, and now that I know that it's a broken odometer gear, I'd like to get my local Volvo repair shop to get it fixed!

I wouldn't mind repairing other stuff, but this sounds a little too complicated to do the odometer repair!

Welcome to MVS,

The flywire came with the car and the DTC boxes are located just behind the windshield washer fluid filler.

This is specific to port A-2 but it is all the same for the other ports. Once you remove the cover you will see the numbers.

More info on getting the mileage for an 850 (mine '94). 2 small covered connector boxes between the washer fluid port and the hood latch. Remove cover to the left box (A), I used a flathead screwdriver from the top, between the boxes, to loosen the clip for the cover. The Flywire is attached to the connector and its metal tip is held in the cover. Pull tip out of the cover and insert into A2 to read codes, A7 for mileage. I plugged wire in, then turned ignition on (to position II), read codes, cleared them, turned ignition off, plugged in to A7, ignition on, read mileage as described.
DO IT, it is VERY easy and so helpful! Odometer broke at 133004 3 years ago and I finally found the energy to fix it, 185,216!. P.N. 13800 from IPD is a little plastic gear ($30) to replace in the back of the instrument pod - also easy, IPD includes DVD with great instructions.

Should the fly wire, have a solid end on it? Mine is a frayed wire, it should still work, right? This is on a 95 850 turbo wagon.

Most of the flywires have the frayed insulation but so long as the wire is still hooked up to the plug it should work. Be gentle with it.

I may have something on that in the next few days.

On 1995 and earlier, you can read the ECU mileage from the diagnostic port as follows:

1. Select module A terminal 7
2. Switch ignition on
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.
