Eric, Thanks for taking the time to walk me through the process of inspecting the hybrid battery ECU. I'll try to head over early tomorrow. I'd like to pull out completely to inspect. Can you confirm that I won't need to reprogram the hybrid battery ECU?
benjita, I don't think eric is currently showing as online. The ecu mounted in the HV battery case is plug and play. It requires no programming if swapped/removed/reinstalled/etc.
Took a day off to recover but wanted to update the group. Eric kindly took some time to chat with me via phone and we decided it would be a good idea for me to inspect the battery ECU. I drove down early in the morning and was able to access it in short order. Attached is a photo of one of plugs that shows a slight tinge of corrosion. Checked-in with Eric,who said it looked good, so I sanded the corrosion off and reinstalled. I decided to just have the dealer install a new battery. I could have bought one from them for $1995 and installed myself but they don't have them in stock, so I'd have to come back down another day. I figure I'd give them the business since they didn't charge for the diagnosis and offered me a free loaner. The work should be done by Friday and the "waiver" the had me sign just said that I agreed that changing out the battery may not solve the problem. I feel safe taking that bet after all the support from the group. Thanks everyone!
Yea, the price seemed reasonable for me too considering how significant the battery is. The car has been great and I'd like to keep it for another 4-5 years so it seemed like a worthwhile "investment" in the car. The dealer's original estimate of $4.5k had me thinking about ditching the car though. You guys saved me from having to buy a new car! The loaner is a Camry
I would have thought they would have put you in a Prime to get the new car juices flowing. But you’ve got your Prius sorted and avoided a new car. Good luck and keep us posted .
