Ok, my CEL came on today after idling for about 10-15 mins. After I got home from my errand's I did the key on 3x thing and nothing is showing up, am I missing somthing to check for the code's? I did a search even and it doesn't say to hold the odometer reset or anything. just in case i am doing it wrong here is what I have done. key on,off (where I can pull the key out but not),on,off,on- and all i get is the odometer, and If I wait a few second's the light will blink, I think it was 10 times it blinked. I'm going to bring it in to the dealer tomorrow but would still like to know what the codes are before bringing it in. Thanks for any help if i'm doing it wrong.

 

Got it to work. I don't think I was tuning it on or off fast enough at first. code was P2609. Now to find what it means...

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.
