2006 issues after inverter replacement

Waiting on delivery of Techstream app and OBD2 reader (Ebay special)


Replaced inverter pump after failure – first problem. Car then started – still showing P0080 and a miss in cyl 2 so replaced all plugs. Took care of the miss.

Now showing the P0080 and P3020 (Block 10 problem). So I purchased Torque Pro and paired with VeePak OBD2 reader and got the attached readout. – does not show a problem in Block 10.

Block 1 sits at 17 volt the rest vary as the SOC can go from 30 to 55 percent and then drop back to 30. – this is in park.

Putting the car in Drive flashes the warning


Caution

Shift to the P position when parked.

The batteries will not charge

if the Shift position is in N Neutral.


At a quandry where to look. The HV was rebuilt (about a year before), vehicle has 240,000 miles but is in good condition and I want to keep it road worthy. Not my only vehicle and in this current day I have plenty of time to tinker.
