I drove my 2003 about 140 miles and sometimes the car was shutting off and the coming back on withing 2-3 secomds ....WTF ....... This would happen every 20 mins or so and it scares the s%&T out of me when it does ? I never have any problems starting the car ? Doesnt make sense I would have thought that these types of error codes P1615 would NOT allow you to start the car NOT happen while your driving ? Anyone have any ideas ?

P1615 is the "DIFFERENCE OF KEY" error.

Maybe not be the same problem, but there are a couple threads on the subject:

It could be a faulty or failing BCM, NATS antenna, key, ECU or any number of other parts. Did you try another one of your keys?

 

Ooooo. Just noticed your sig: "flood car". No wonder you're having flaky electronics problems.

 

The BCm, and ECU were replaced. The key I was using is the original so I will try the other key I had made up and see if there's any difference .....Will let you know ......
