C1259 hv system regeneration malfuction and c1310 malfunction in hv system codes showing after i replaced 2 cells on the hv battery. Screen shows the hv battery does charge while driving, gets full green bars, however it discharges quickly and the electric part of the engine never kicks in, the car only drives with the gas engine. At a loss here. Help??
Are you 100% sure you correctly inserted the orange service plug. It is a 3 step process 1) Insert orange plug into battery pack 2) rotate handle upwards 3) slide orange handle straight down until you hear it click in place Step three is the one most often missed. Go in back right now and go through 3 steps. Not 1 step. Not 2 steps. 3 steps! edit: Also, double check that all computer harnesses are fully engaged.
I would get a scanner where you can see live data to discover the problem. Especially HV ECU info. You saved money on buying a battery. Put some of that money towards a better scanner. Your going to need/want it for future repairs you will be doing to the pack. Feel free to call me and chat.
Is there one youd recommend? I ive seen another recommended on here, i think its called The mini scan vac?
