Took seats out and disconnected airbag and seatbelt sensor from the seat put everything back together and surprised to see my two dash panels sensors are still on.

The seats have a couple sensors. By you removing the seat and disconnecting, you caused an airbag code. This is most likely the occupant classification detection. (the sensor that detects someone is in the seat) (and position of the seat)
This will need to be re calibrated into the airbag ecu. This is only done with the Toyota scan tool.
You need a trip to the dealer sorry to say. Should take about an hour. Your seat belt applies also.
