Hybrid 5 system fault, low battery - How to reset
I have a hybrid5 F10 N55 with hybrid system fault. In the beginning there was an interlock loop open circuit fault. I found the car had hit something and dislodged an interlock loop underside on the starter/alternator electronics box. Repaired it and that error cleared.

Now I have hybrid fault low battery. I can run engine but no accelerator and gear does not shift. System reports high voltage switch disconnect. I suspect because of the previous interlock fault.

I cant find an abl to switch back the hv switch so it can recharge the hybrid battery. Beginning to suspect that ABL is available only on ista online?

Any other means to charge the hybrid battery? Possibility of remote assistance with this?

RE: Hybrid 5 system fault, low battery - How to reset
I got this car to back on the road after replacing gearbox. I noticed old gearbox adaptations were all reading zero so probably a dead alternator.

However the acceleration in higher gears is rather weak. I still have hybrid fault and flat battery so I guess hybrid system is gone for now. How is it supposed to run without hybrid? On cold start accelerator pedal is dead for a short while. No dme faults that I can relate.
