I feel every computer has a different tolerance for trouble codes... I got the SES the other day, all i was told a hose was disconnected, I figure a vacuum hose, but hears the kicker i was told by my mechanic, that according to the comp, i was doing 84 mph?!! I have not hit those speeds in awhile. I think the comp in my car has a delayed reaction to things...
Supposively there is a light to tell you a light is out, it doesn't seem to matter people since there are a lot of rides with lights out, especially the taillights on the G/a's.( i know i have one out myself right now) I've never gotten a svs light for a light...
