This morning on the way to work my Check Guages light came on for a shot time (2-3 seconds). When I got to work I used the key on/off trick to check codes and there were none. Do you guys have any ideas what is causing this condition?

 

This is a problem or should I say a minor annoyance with the early 03s. Mine does it occasionally. There was a TSB but it requires the radio to be unhooked if you have the high-end Infinity system. For this reason I decided to just live with it. It doesn't do it often enough to bother me. It did do it yesterday. That was the first time I have noticed it in months.

 

Same here. I just ignore it.

Mine does it too. It's just an annoyance that I learned to live with.

 

Is it associated with a chime? If it is the same as mine, it is a loose connection on one of the tail light bulbs. I tightened up the bulb connectors and it goes away.

 

I think that I've found my answer. TSB 08-004-03 is for an Electro Mechanical Instrument Cluster flash. It states that it is a reflash to the MIC software.
I was wondering if this is a reflash of the ECM also. Anyone got any clues?

 

I've seen mine do it too and it seems to be a catch of the eye thing cause its just a second. Mine has not done it for a long time though
