I think some lights just stay lit longer than others. Probably longer diagnostic tests or something. I know my airbag/security/and a few other lights stay on longer.

Default PCM Burps....

Has this ever happened to anyone?

You turn on your car, start it up, everything fine. You look down at your gages and realize that some of the cluster lights are still lit.... for example airbag, or service engine, or any other. You turn off the car, start it up again, and everything is fine.

This seems to happen to my POS every once in a while, but is simply fixed by turning it off, and on again.

I have checked all of the grounds behind the cylinder heads, and have gone over most of the wiring (that which I could follow). The only thing I can come up with is that the PCM just burped out some bad data?

Anyone else have this problem, or anyone know what causes it. Is it a sign of things to come for my PCM?

They actually will stay lit for the entire time that the key is left in the on position, until the car is shut down again.
