1.
Disconnect the connectors of inverter cooling radiator fan, inverter
cooling pump, inverter, and HV ECU2.
2.
Using the electrical tester, measure the resistance between the
terminals of inverter cooling radiator fan connector and inverter
start relay connector (relay block side).
3.
Using the electrical tester, measure the resistance between the
2nd terminal of inverter cooling radiator fan connector and the
ground.
