Can you do a systems check in a 2004 ls 430. My car has red triangle lite up w/ exclamation mark in middle. It doesn't tell me what is wrong. Is there some kind of test the car does on its own that will tell you what is wrong?

For me this is usually a tire pressure sensor issue. Even though my tires hold pressure well, I have to reset the TPMs every so often when the red triangle appears. But Tee is right, the lower left display panel tells you the exact source of the problem.

Maintenance is some preset junk that comes up every 5K miles or so. It's not linked to anything in particular, just a "dummy light" to say time to lighten your wallet at the dealer.
The tire pressure is a specific light that comes on, so it won't be the tires for that light.
