What do these lights mean?
 

Hello,
I have an everyday driver 2000 V70 with 178k miles. Recently, two service lights came on (see pic), then went away after I turned the car off and back on. It has done this again several more times since then, sometimes going off when the car turns off. Any ideas what these lights in combination mean? Just had rear brakes replaced 1 month ago.

You'll need to see the dealer to see what code was set. The dynamic stability control shares control of the brakes with the antilock braking system, so any component having control of the brakes would affect both systems and turn on the two lights.

unfortunately - its usually the abs control unit that fails
