Grounding issue "Circuit low" = ground wire problem or another system on the same circuit using too much current.
Check all wiring issues and then correct the issue to have the code go away :)

This means that the secondary O2 sensor detects that the catalytic converter
isn't working as efficiently as it should.
This engine code can be triggered by any one of the following:
1.) The catalyst in the catalytic converter is cracked, clogged, or otherwise damaged.
2.) The secondary O2 sensor is malfunctioning.
3.) There is an exhaust leak.
4.) The computer unit is faulty.

I'm not sure about your model, but some Volvos come with a little screwdriver hole adjacent to the headlight switch that you can turn to shut the DRL off. I believe the slot needs to be horizontal to be in the off position.
