"Check Hybrid System" message shows up on dash display. Went to parts store and the troubleshoot codes are P0171, P0A93 and C1241. The Fluid in the inverter coolant tank was low so I filled it up and the light went off. I drove it 70 miles and light is back on. Coolant level was low again so I filled it back up but the light saying Check Hybrid System stays on. What could be wrong?
