    Start with P3140. There is an orange, safety interlock in the battery. Make sure it is in the down and locked position. This closes a microswitch that passes a signal from the inverter, through the switch, and to the HV ECU.

    P3009 and P3004 indicate the ground-fault detection circuit has gone off. It could be a bad cable but I would not rule out a failed module that has a resistance leak to the battery case.

    Was the weather unusually humid just before this happened? If you have a failing module, the leaked KOH can on a humid day trigger similar faults.
