Daytime running lights
As of yesterday, my DRLs stopped working. They are turned on using the options in the DIC. They come on if I turn them on using the stalk. they come on when I lock/unlock the car. The fuse #2 under the hood is good. Now, I pulled three codes...all current: B0502, B0507 AND B2482. Those are the R/L DRL circuit relays and the backup lamp relay circuit. Would all three relays go at once? Any ideas? Thanks!

Those are the codes you would get if you pulled the A2 fuse. Seems strange that you have no DRLs at all and I would have suspected the fuse being the problem. A relay failure would be more likely to affect left or right but not both.
It may be worth changing the fuse on spec but its a mystery. I'd check the bulbs as the next step.

yes, I'd replace the fuse first and then inspect the bulbs. BTW, there is no DRL option setting in the DIC to control whether they are on or off. The only way to disable them is to pull the fuse...on second thought...you may want to check your emergency brake switch. You can turn off the DRL's by pulling the emergency brake handle at least one click. Maybe the switch is out of adjustment.
