On my way to work it was raining pretty hard and I didn't see the flood and drove right into it. I got to work and even was able to get home with no problem. A couple of hours later I had gone to my car to go somewhere, and it wouldn't start. It had no lights, no power, no nothing. When I looked under the hood didn't notice anything wrong except my fan was on.
Do you
have the same problem?

It sounds like there is a problem with the vehicle electrical control module or the battery has gone out, I would remove the battery and have it tested at the auto parts store first. Here is the location of the VESCM so you can see if the electrical connector got wet. Also try to leave the hood open in a dry area to help remove the moisture from the engine compartment.

Vehicle Electrical System Control Module -J519-, Replacing
The work procedure "Vehicle Electrical System Control Module, Replacing" contains the following scope of work:

If a new Vehicle Electrical System Control Module -J519- is installed, it must be coded online.
The factory mode in the Vehicle Electrical System Control Module -J519- is deactivated.
All of the remote keys are programmed again.
The procedure to "replace the vehicle electrical system control module" can only be performed with the Vehicle Diagnostic Tester in the "guided fault finding" function.

Procedure

Replace the Vehicle Electrical System Control Module -J519- using the Vehicle Diagnostic Tester in Guided Fault Finding, Replace vehicle electrical system control. Check out the images (below). Please let us know what you find. We are interested to see what it is.
