I was recently detailing the inside of the car, and I noticed that every minute the dash lights would flash, and the message center would say "system check". I figured since the doors were open, the car was doing some type of diagnostic.

Fast forward to tonight, and I noticed the dash lights flash as I walked by. The car is in park, windows up.
I stood outside the car, and timed the lights flashing. Every 60 seconds, the car does a "system check".

Has it always done this, and I just never noticed?

Any input on the "system check"?

Thanks,

 

Are the keys in the ignition in the second position? I don't think it's supposed to do that. Mine doesn't. That actually worries me because I think it might deplete your battery.

 

It is only supposed to do that when you first turn on the ignition. It sounds like it is a wiring fault, an ignition switch fault or an instrument cluster problem.

I agree this will cause an abnormal battery drain when the car is off. if you drive the car daily though, it might be small enough to ignore.

 

Key NOT in the car.
