Separate names with a comma.
It sure sounds like some of those codes could have been caused by a forcible stop and damage to the front end. And the ECUs in question are...
Missing the fact that the coolant reservoir was empty sounds like a bad mistake. Sure, everyone makes them, but shouldn't lie to cover them up....
Just disconnecting the negative lead is pretty easy, though. You need a 10mm wrench. Lift the battery cover and look where the black wire bolts...
Ditto about recirc--use that mode sparingly. If the heat turns off, can you get it back on again by increasing the setting? Are you using...
I use this website to look up part numbers. Plug in your VIN. Yes, you should have a multimeter. They practically give them away at Harbor...
What is the condition of the spark plugs and coils? Can you check the fuel pump with Techstream?
It looks like it's part number 83320-47080 and they go for about $80 or 90. Whether replacing this part would fix the problem is another issue....
It seems like every piece damaged costs $1000 to fix these days, and you have at least two pieces damaged, so yes, it sounds like it's in line.
The problem appears to be limited to long steep low-speed grades, say those exceeding 10% and over 2000' drop. It's not just the Prius that...
You can fix that with a new fob and the Mini VCI, a cable that plugs into a laptop and gives you full dealership software options, including key...
Keep an eye on rear brake adjustment (North America only, I hear). If you never use your parking brake, they might be out of adjustment.
Changing the inverter/transaxle coolant is a little involved and it's critical to get it right. Get detailed instructions and be sure you...
I have driven my Gen 2 180,000 miles in the Colorado Rockies and this is my experience as well. I check the brakes at every tire rotation and...
How old is that battery? If it's over four years, get a new one.
Have you replaced the PCV valve lately?
Just a guess here, but maybe the codes are Prius-specific ABS codes and you need Techstream software to read and clear them. I'd try a Mini VCI...
After I've replaced tie rod ends, or done any front end work myself, I always take the car to an alignment shop for final adjustment. I've always...
Agree with the above--sounds like a rubber bushing failing, from age/exposure not wear. Any good alignment shop could find and repair this, no...
This would not answer the OP, but maybe the new question. Do all the rest of the steering wheel buttons work? If not, it may be the spiral...
Yeah, the PCV change is a "Hail Mary." It's easy enough to do--as I remember you have to dismount the relay block.
