Default What do these codes mean?

I took my vette to the local dealer to fix my a/c and had them look at the codes that were stored in the pcm. They were: B1026, B1061, P1431, B2723, B0521, U1064, & U1096. Does anyone know what they mean?
:confused:

the U codes are class 2 communication codes.
Ignore them if they are not current.
The P1431 is a sign that you may have a fuel level sensor problem.
Does your fuel gage ever unexplainably go to E?
The B2723 indicates you may have had a glitch in your PassKey® system.
Do you ever have problems starting your car?
(won't crank).
All in all, if your car starts, your gas gage works and you don't see any warning lights those codes are incidental and should be ignored.
If you had come to me for service I would note them on the Repair order, check for any symptoms and recheck for the same codes if you brought your car back and I had the scan tool connected.
If the codes come back over and over there could be some sort of problem.

both of these codes are for your air bag system.
B1061 is a LAMP Circuit Failure for the Air Bag Warning light.
B1026 is Driver Deployment Loop Open message. It could be caused by a bad connection in the driver's side air bag connections in the steering wheel.

Anybody done anything with your steering wheel lately?

Well, my fuel gauge goes to empty almost everytime I drive the car for a long time. My airbag light is stuck on. My car didn't start a few times but I think that was due to the alarm system re-arming itself but I could be wrong. My tach stopped working a few times but I figured it was the white face gauges curling when they heated up. I guess most of these codes aren't to serious so now I feel much better. Thanks alot for the info guys!
