    The skid control ECU is responsible for reporting all of the logged DTC. It seems unlikely that in fact all of those sensors are bad.

    When you expose the ECU maybe you can inspect the wiring harness connectors to ensure there is no damage. If liquid had been spilled on the dashboard, or the car had been in a flood at some point in its prior history, that would cause significant electrical issues.

    That sounds good.

    Is there anything that can be removed that would make this all come up. Car was perfect no codes at all. Then when I got it back from leaving it at a shop this all came up... Unless the DTC were stored and just needed a few miles to show up?

    I can't even reset the lights they stay on even after I unplug the batter 12 volt and let it sit for 10 min...

    This is a key piece of information, don't you think? What work was performed at this shop?

    When the skid control ECU and SRS ECU log DTC, those codes will not be lost by disconnecting the 12V battery. It is necessary to use a jumper on the OBD-II socket, use Mini VCI, or a generic OBD-II code reader to reset the DTC.
