The hybrid battery in my 2007 Prius had two bad cells after replacing the bad cells with a new cells and balancing the battery as a whole and replacing the battery back into the car the car ran for approximately 20 miles and then all of our error lights came back on and the hybrid battery was no longer giving power. The following is a list of all of the Error codes that we are dealing with.
Hv system regeneration malfunction
Malf engine control unit
Malf in HV system
Batt block 13 weak
Has anyone had similar problems or have any advice please help we're desperate to get this car back on the road.
We also replaced the 12 V battery & cleaned out fan after reconnecting the 12 V battery, all of the Warning tree lights go out. Then after driving normally for about four miles, the hv fan goes on, about a mile later I hear a solenoid click and the car gets sluggish with no power from the traction battery. If I pull over turn off the car turn it back on Warning tree lights still on and car drive normally for one-mile with fan running.
