[QUOTE="WestCoastDan, post: 455155, member: 23120"] FYI, on my ‘15 I recently messed w/ the JScan settings to customize the DRL settings while trying to get my aftermarket fog lights to work using the factory switch. This managed to eliminate both corner brake lights. The center light still functioned normally. While troubleshooting, I learned that there is no fuse for the corner brake lights. Their function is controlled within the ECU for some strange reason. Not sure if this also applies to your model year, but knowing what I know now, I would check for any codes if you can and clear them. I’d also undo any possible changes you may have made while customizing other settings w/JScan or similar tools. [/QUOTE]
