Instrument cluster had been reworked. Then various warnings appeared in the information screen. The security warning light can on, air bag warning went on & off. Thought it might be a loose connection so unplugged and replugged but the odometer reset to zero. Is there anyway to reset to the correct reading?
SOURCE: ABS WARNING LIGHT ON VOLVO V70 1997
ABS light comes on with ignition then should go off when you start the car.
If abs sensor does not turn off after disconnecting the battery, then
there is a real problem, a faulty sensor or ABS malfunctioning.
When the ABS led comes on immediately after you start the car and stays on usually is one of the relays.
The main one is called surge arrester relay, if it is faulty usually there have been an
overvoltage.
There should be two more, usually located behind the black plastic cover of the ABS.
Testing and changing the faulty relay can fix the problem.
If light turns off on startup, and comes back on when you reach some
speed, usually you need to check the wheel sensors. You test them
unplugging the sensor located behind the wheel and testing it for
continuity with a multimeter.
Use Haynes manual to find locations and specs of relays.
Contact a qualified mechanic if you cannot fix it yourself, problems with ABS may compromise safety of the vehicle.

I remove two panel underneath the steering column. The first panel is removed using a 10 mm socket. The second panel is removed using a torx socket (can't remember the size). Removing these two panels gives you room to get to the clip on speedomter. Looking at the speedometer, you should see two rectangular holes on each side of the speedometer cover. I use a awl to push in the clip (you could use a screwdriver). Looking underneath the dash, you should be able to see the clip you are pushing on with the awl. I take my 2nd awl and put it behind the clip. I get the left side to release. One the speedometer cover releases, you can see the speedometer. You will see the 4 torx screws (t20) and two smaller clips holding the speedometer. All that is left is the wiring. (I take a sharpie pen and mark one of my wire locations on the speedometer. I am not sure what it does. It is a single wire.)

After swaping my radio I had this same problem. The dealership told me that I must of unpluged the little rectulanger plug on the back of the temputure controls, and I did. After they reset it I never had that problem again. That lesson cost me $25.00
