Help with P2509 Code
 

Hi guys my truck has been running GREAT until this morning .I was out of town last night and returned this morning to start my truck and low and behold no start just click , click .... So I was WTF you have to be kidding me right?? So I check for any switches that I might have left on and nothing everything was cool I had plenty of power for the interior lights and dash lights.So I checked for loose cables etc and all is good , so I jumped it and she fired right up! Then I hear "DING" and I did the ole key trick and bang "P2509" on the odom and the engine light is on ???? My truck is only 1 yr old and 14,200 miles on it. What else can I check for ?????

Thanks for the help in advance , all is appreciated!!!!!!!!:U:

P2509-POWER DOWN DATA LOST ERROR

Should clean all terminals and ground points, then coat em with some terminal protector. As far as the CEL, should go out the next 100 miles or 3 engine starts.

Other conditions just in case it should happen again.
