Thank you for choosing JustAnswer and allowing me to help you resolve your Toyota questions!
Do you have the code numbers that the dealer used to base the diagnosis from?
The hybrid systems are all about the same. Minor differences but to diagnose you have to start with all the codes. If you have a VIN or specific model number I can cross reference the inverter to other models.
The inverter number is G9200-28011 unfortunately it does not cross to anything that is used here in the USA but the systems operate basically the same. The Estima is not used here in the USA but is comparable to the highlander system due to the engine size and using the 2AZ engine. Let me know if you can get the code info.
89890-28020 would also need replacing as when the vehicle has batteries removed, the ecu would not be able to be revived after installation of the replacement inverter, have you heard this issue with hybrids?
I have been fixing hybrids since they came out in the late 90s early 2000 and have never heard of this. Again I don't have any code numbers to base or verify what they're telling you but this definitely is a stretch on replacing the computer. I would even be suspicious of the inverter but need the code numbers. The number for the inverter is probably the latest number my information is slightly old because world market cars and information is harder to come by here in the US. For the other vehicle if you have the vehicle identification number I can check to see if it comes up with anything.Skyvisions
