Thanks Lee, very helpful!

This series of codes seems to repeat no matter what I replace?

Thanks again. It's been throwing codes PO422, P1550, P1618, P0722

Really love the car but these electrical issues are driving me nuts.

Thanks for the tip, sounds like the ABS Module may be the culprit??

My 2000 Cross Country V70 AWD throws me 5 warning lights, (brake, check engine, track, flashing arrow), I've replaced the 02 sensor and the speed sensor, but still get the lights and no speedometer or odometer. Any guesses for me??
