Toyota Repair: Toyota Camry, toyota camry 1998, toyota camry

Question
We just purchased a Toyota Camry (1998) with 118,000 miles. I it seems to run really well, but we are concerned with the check engine light being on, the trac control light being on and all of a sudden the air bag light is on all the time also. It has a smooth ride but when we go on roads that aren't very good it sounds like there is something rattling in the back end. We though maybe something was loose where the spare tire was but that wasn't it. Would you know anything about these problems? Thanks

Answer
The check engine light is on because there is a problem with an input signal to the onboard computer, the trac light will turn on anytime the check engine light does so the first thing to do is to have a diagnostic scantool connected to the computer to find out what the diagnostic trouble codes are, I would recommend the toyota dealer do this, the air bag light is not related to the check engine light, there should be a seperate trouble code for that.
