For the Gen II Prius, Relay P5 is under the dash on the extreme left side, so it is not easy to get at. Relays are very reliable, so it would be...
Prius_Aki, where are you located? Please put that in your profile. There might be an independent shop willing to install a used skid ECU.
The battery ECU rarely fails. Toyota replaces it as it is inside the battery case, and they are just swapping the entire pack as a whole. $1900...
This whole thing is ignorable. It really is a very minor engineering mistake, and the only way to resolve it would be to reprogram the AC ECU....
Make sure that the radiator fans are blowing the proper direction. If the repair place reversed the fans, the air blows out, rather than in.
On the Prius, P1150 points to the flow control valve at the coolant heat storage tank. It has nothing to do with the A/F sensor. It is not...
Yes, according to Toyota: ESQ - Nickel Metal Hydride (NiMH) Keeps us posted. I think the idea of adding some electrolyte has merit. Is that rice...
Also try the various air flow positions as well: defrost, foot well, etc. Make sure the flow is directed as expected. You again should hear the...

How was the battery rebalanced after the module swap?
