2016 prius c check hybrid system problem. not going into ready

Hi? i am new here, i noticed the coolant was not moving in the reservoir, i had two flash of the over temp on the dash but doesn't stay on. i bought the inverter pump, i drove the car into the garage to change the inverter pump and coolant as well. i disconnected the battery, i removed the inverter completely out to get access to the pump. i removed and replace the pump, connect all the wiring and hoses. add coolant, i tried to start the car, everything turns on but it will not go into ready. the message pop up check hybrid system, pull over, . the dash light icons stays on. i used obd to check, it says no code. prior to doing the replacement of the pump, there was no obd code. please help.

i tried removing the white wire in the fuse box still no start. i need guidance on what to do next.

thank you very much for your wisdom and ideas

 

Yes i removed the orange plug and when i was done working on the inverter, i plugged it back. all plugs were put back and screw down. all bolts removed were install and no bolt left out or left over.

 

hi , what scanner do you recommend to used?

 

thank you. i did. orange clip is pushed up and connect with the other socket on the side of it.

 

thank you very much

 

car still not starting after removing inverter and replacing the pump. i am still not able to get codes from the vehicle.

there is a terminal at the back of the inverer while i was threading the nut back on to that terminal there was an electrical spark. i forget to disconnect the 12volt battery when i worked on the car. could the spark destroyed the inverter or or fuse. i believe that wire to the inverter is the dc/dc inverter wire.

 

everything include radio turns on. can move into gear and out of gears. but it will not say ready. when i walk next to the car with key in hand and driver door i hear sounds in the hood but will not go into ready and will not move . all else will work just fine. the inverter pump i replaced is not getting power because all the new coolant i added is not suck it like wise the radiator coolant is not being sucked in.
yes motor generator not turning on
