I had these lights come on. Not sure yet if regen is affected as I was in a rush to get to work in the morning. Browsing through here, it seems like I should short CG/TC pins on the OBD II and read the codes. I do not have the manual to match up the codes, however. Can some gentle soul point me to a link or give me a PDF to refer? I did have the front brakes done last month so will be checking there as well.
