On our '98 XC70 with 96K miles the ABS and TRACS light came on and stayed on until the car was shut off. Since then (a couple of days and 50 or so miles later) neither light has come back on.

1) is this an "early warning" of some major repair like replacement of the ABS module?

2)Will the OBD codes give any idication of what the lights meant?

3) should I be concerned driving it as is?

Thanks!
Jack
