C5 Numerous Engine & Trouble Lights Illuminate During Driving
While driving the C5, without any prompting, numerous engine trouble lights come on including the reduced engine power indicator and the radio/CD player and Air Conditioning go off. To correct the situation, all I have to do is turn off the igintion and restart the engine and everything returns to normal. This continues repeatedly and I sure would like to know what the possible cause and corrective action might be. Any suggestions?

Thanks! I ran the diagnostics and 1 code appeared that wasn't historical (H). The code that appeared was: 40BCM - B2721C : PASS-Key Detection Circuit. Not sure where to go from there.

Well several possibilities. Exam your Key, the key pellet maybe dirty or loose. Clean the key pellet with some rubbing alcohol. If loose need to get a new key made. You may have problems with contacts in the lock cylinder where it reads the Pellet. And finally you could have a bad connection at the Ignition switch and/or BCM.
I would hope for the basic of a dirty key pellet.
There is a post on the forum about testing your key pellet for proper resistance and determining if it is the right value for your car. There is also a post about ordering the right Pellet or something to that nature. IMHO to much of a hassle. If you have a friend at dealership just have them make a new one.
1016 was a result of the 2721 May have a bad switch, but you must assure all your connections and grounds are good
