I don't know their logic with it.
I got a "Service Vehicle" message on the dash, plugged my obdi scanner in, and nothing came up.
Brought it to my buddies shop, he plugged his scanner in (don't remember what he has) and it showed a code for the oil pressure sensor and my thermostat.
But the CEL did not light up, and yes, the fuse was good as are the bulbs.

...
I'm just a guy that enjoys my Ions.
Try Google, first. Then ask.

REWARD EXCELLENCE!
