06 Sonata ESC, ABS, will not come out of drive, and brakes are light.
 

Driving down the road and the ESC, ABS lights came on. I pulled into a store to check it out and try to put the care in park and I could not, it would only go into neutral. I got a screw driver and hit the lock release on the shifter and got it in park. Finally got to turn off the engine. When I started back up I had no lights on. So when we got back in town I brought it to Auto Zone to get it hooked up to a code reader. When they hooked it up nothing happened. I brought it over to ORIELLY to get it hooked up and it says there is no ECU hooked up. Possible ECU?
Before all this every time we started the car it would reset all the electronics like disconnecting the battery.

thanks to all who could help me

Check the brake light switch on the brake pedal. Very common problem that could cause those issues.

Did you find out the problem? Fixed?

To me, it sounds like the ignition switch
But, one should always go through the steps to test to find the real problem

Good luck and please give an update on your situation
