Lights on while car is off

This morning my keyless entry was not working (tried extra key still nothing), when I got closer I found out there are few light on the dashboard while the car is turned off. Battery, oil, DSC, cruise control, and automatic transmission/sequential manual gearbox and as well as the brake light on the back of my car are on.
The car drives fine and all the lights go away once I start the car. but come back when I turn it off..


So far, I have got the battery checked, its fine and pulled codes only code thats new is P0442 Emmission control system leak, that is my bad fuel cap most likely.
P0171 and P0174 been there for my low fuel pump fail..

Never trust the average battery test.
How old is your battery?

I drove around for a while, if the battery was bad the battery light would go on...

Incorrect. The idiot light does not detect a weak or erratic battery.

I understand, just I've read about so many getting a load test and eventually it was the battery after it tested OK.

That is false. Not a little false, completely false.

The Battery Light tells you nothing about the battery, because it is really a Charging System Failure light. The light means that the charging system is on the fritz, it does not mean that the battery is dead.

The battery can be deader than a doornail, and the light might not be on, and the battery can be brand spanking new and the light will not go off.

That light tells you absolutely nothing about the battery EXCEPT that if the light is on, you can be sure that the battery will be dead in a few miles -- the number of miles depends on how many electrical loads you have running at the time.

I just noticed your temperature needle is on the red. Is that just not working?

Yeah, then the temperature gauge is whacked too.
Should never rest in this position.

This could be an expensive problem to troubleshoot. Now I'm starting to think you may have a problem with the gauge cluster.
I'd still like to see a different battery subbed in there for comparison. Too bad you don't have a friend.

That is what I think as well, but not sure so just bouncing ideas to make sure. I also heard about the short in the tail lights that causes cluster issues.

Completely logically then to repair the short in the tail lights to see if it's a fix.
As that is by far the easiest thing to repair first as long as we're guessing.

That's odd -- the only time my temperature gauge went to the red was when my cluster didn't have a connection to the DME

Fuse is not blown unless the line is broken inside the fuse. Its very noticeable.

Only other thing I can remember that has to do with the cluster was about two to three years ago I was driving on the freeway on a hot summer day, with the A/C, cruise, and lights on. My cluster gave out for like 10 seconds (went blank all the needles went dead nothing) then came back on and nothing else..
