Hybrid tends to stall/shut off coming out of Auto Stop mode on occasion. Looking for feedback as to the possible root cause? Auto code pulled is P0AC4 which refers to the PCM/ECU. If I remove the Hybrid disconnect and 12v battery will I have issues with power components when batteries are reconnected?
So, after all was said and done with fixing everything on the internal combustion engine and the connections, etc., I have determined that whenever you get the dreaded P0AC4 code, it almost always requires a new hybrid battery pack. What did your dealer say? Any updates?
If you are in the Eastern US, there is a fairly new company out there called GreenBeanHybrid. They'll put a remanufactured battery installed at your home for $2,349. It comes with a pro-rated 5-year warranty (after 36 months, it's relatively worthless). It may be an option. I've found allegedly new batteries for around $2800, plus shipping, plus core. Shouldn't be hard to replace yourself, but these Green Bean guys will do all that - remove the old, install the new, reset the codes, reprogram if necessary, in your own lot.
