reprogramming, mdi2 and SPS-2 questions
About the middle of Michigan. Soo not sure what to make of this. Last night I disconnected the 12v and put it on the charger. In the morning the 12v was charged and the HV battery read 265v.

I do most of my friends and family's car repairs but have no formal training. My uncle has a 2011 Yukon hybrid that's gone stupid on the hybrid side. He took it to the dealership who diagnosed with a bad Drive motor inverter. As a new one was like 6k we opted to get a used off ebay and the...- lesmiserah
