I just did a google search and found this. Not sure if it helps or not, but at least it's something. And to reset it, just bring to your local checker auto/napa/whatever and have them reset it.

The P2609 codes says that you have an abnormal voltage drop to the intake grid heater. That's usually caused by a bad battery (even one cell in one battery can do it). Do a load test on each battery. If they're OK you've got a bad grid heater. The only way to clear it is to drop by your dealer. John
