The running voltage is within spec. Clear the code and see if it comes back.
Bill,
Cleared it a couple times, but it comes back about 20 seconds after starting engine.

When I had that same problem it was the worn-out brushes in the alternator. When they start to get bad they are somewhat intermittent. I'd take the alternator off, take it down to Autozone, have it tested, tested OK, put it back on, and it would stop charging. I finally changed out the alternator and all was well. YMMV.
This model often had a problem where the regulator portion of the BCM would go bad. It can be tested by connecting the field circuit directly to the battery.
Daniel Stern, a former poster to this NG had outlined a procedure to perform this test. Perhaps it is on allpar.com?
