I have a 09 dts and got code P0690 changed relay worked fine for one day and check engine light is back on. The car runs and drives fine has on 83,338 miles volts check out to 14.6 what possibly could be the problem never hesitated to start. It’s the premium version with a lot of options including lane keep assist, blind spot monitoring, navigation etc. My scan tool say 0 dtc but that code P0690 is in there and will not erase. Sometimes when I start it the light goes out like it supposed to. Lost!!!!
Mine is the same way my next option is to get some cleaner and clean everything around it and all the connections
