Thanks for the followup. .
Yes, the HV battery ecu is inside the battery case behind the rear seat. Here it is with some of the covers removed. It's toward the left...
If I suspect that there's a head gasket problem, I use a pressure tester on the radiator (to 15psi) and leave it pressurized overnight. The next...
You can use search either in the forum or google. (If you're keeping your Prius, you might consider hanging onto DrPrius just to keep tabs on the...
Hello, and welcome to Priuschat! You have several codes that point to other thing(s) going on. C1310 is set in the ABS ecu when it sees that the...
So, each ignition coil is controlled by the ECM on individual IGT circuits. If the coil primary circuit switches correctly, it sends a...
The wiring diagram shows the horn(s) are fed by a single black wire. .
As mentioned, MG1 has a software speed limiter. Under normal conditions, the hybrid control will start the ICE at around 40mph to keep MG1 below...
The service info mentions using a capable scantool to perform torque sensor zero point initialization then zero point adjustment. I might want to...
Nope. The driver's window motor has hall effect position sensors built into it that report back to the control IC in the master switch. None of...
My first thought is that you received a set of counterfeit spark plugs. Where did you buy them? .
If you can raise & support the car "safely", then drain the transmission. Measure how much came out. Assuming that the amount is close to the...
If you are not very DIY, I would pass on this. There's a bunch of Prius specific things on these cars, and several can be quite pricey ($$) to...
Which if you want any help with, we need data. Per post 41, exactly which warnings did you see, and what temperatures at that time. What codes in...
I would also clean the engine throttle body bore (the area where the blade is - when the throttle is closed). It might be useful to look at the...
Lots of good suggestions. I ended up going with the Ecopia EP422+, mostly because when I looked up LRR tires, many brands do not make 15" versions...
Unplugging the HV disconnect plug (fuse) then attempting to go ready should set a code (with INF) in the hybrid control ecu. Engine codes in the...
<shrug> then keep using the app all the time. The battery ecu has a number of codes to cover problems with the temperature sensors, the fan...
Great, please do this and show everyone. If you have a better solution, then people will go for it. Whatever app and device you have, will it...
Can you post a picture of the warning light you get, as well as whatever trouble codes you pull from the HV battery ecu. Again, my experience on...
