Anyone able to help with performing diagnostics on SP90D?
Local SC are no help as it's a salvage car.

Have OBD2 adapter cable connected and using TM-spy on IOS but need proper diagnostics carried out to find problem.

Car will not drive/charge
Error messages:
Car needs service - Unable to start car
Power reduced - Vehicles systems shutting down
Unable to drive - Voltage supply too low

12v drains as nothing coming from DC converter, front or rear HVJB. Opened rear HVJB and checked fuses, all ok.
Pyro-fuse ok.
HV battery still holding charge at 107 miles and has held this for over a month.

I haven’t removed battery. I think contractors within battery are ok. Is there anything else in battery to check?
