extracting mileage from ECU 850 1993

posted by  someone claiming to be poolman1 on  Wed Feb 23 07:24 CST 2005 [RELATED]

I just successfully replaced my broken odometer gear with IPD's kit. It was really easy to do! One of you guys already told me that you can extract the real mileage of the car from the ECU through the DTC socket A7. I was able to get the mileage but I checked it after driving the car for a few miles and it spit out the exact same mileage as it did the first time. I know it should be a few miles higher. Does the ECU record the mileage in real-time or does it update the miles on a regular cycle? Thanks for all of your extremely valuable knowledge!!

    As quoted by NateB on this board a while back:


    You certainly can pull the mileage off a 1995 Volvo thru the ecu- Here ya go :

    Here is how to read your mileage if you have the black computer boxes, worked for my 95 Volvo 850 Turbo:
    1. Switch ignition on
    2. Select module A terminal 7
    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.
