My 2009 LS460 RWD BASE’s trac control light is on and the VSC system check (have vehicle checked by dealer) keeps popping up. I am not sure what the issue is but I’m reading stuff about the gas cap (which I ordered vehicle specific), battery disconnect and reconnect (which I’ll do tomorrow), and some sensors as well. I would definitely appreciate help on this and what I should do whether it’s to take it to some mechanic to do a scan or what.

 

Better to scan and post the codes .

 

Check your coolant level too...that's what caused those lights to pop on in my car. As ALK said, you really need to read the codes to see what's going on.

 

spare tire pressure too low, maybe fix that first and see
