Dr Prius for Prius C

I'm not used to using an app to pick cars, but the data suggests that there isn't a problem with that battery right now.

Toyota builds the c battery to last 8-12 years. That one ought to drive great with those scores, but you'd want to establish your battery replacement plan right away so it doesn't catch you unprepared.

Good luck!

 

Looks like quite a few, yes. But none have associated "P" codes registered. Usually when something is serious enough to really matter, the computer stores a "P" code that really just means "hey get in here and read these others." Usually it will also illuminate the check-engine lamp.

I haven't monitored our car with a tool sensitive to "U" codes, so I couldn't tell you if the ones you found are the normal pattern of "log file litter," or something accidentally left over (not cleared) during a previous repair or if it is evidence of a new problem.

Have you test-driven this car? it would be essentially inoperable if the ECU couldn't communicate with major subsystems as a current or persistent condition. Not the sort of thing you'd miss on a spin around the block.

 

I can't account for what you heard, but if you aren't used to hybrids everything about them sounds strange.

 

One way of monitoring dtc codes is after documenting and searching out their meaning (search terms I use are " toyota dtc 'error code #' ) .
If either the free version of DrPrius or Car Scanner allows you to clean dtc codes, you can do that, than monitor to see if and when any of the cleared codes come back. If none do there are reasons why that are beyond the scope of this post. But if dtc codes do reappear, posting the descriptions for what you have done and what you are seeing now should give everyone reading this thread a heads up about your questions.

 

I hesitated to comment on the DrPrius screenshots mainly because I'm not familiar with the C s normal voltage range and not being sure if 165 volts is normal or high, which could explain a lot more about the screenshots you posted. But if 165 volts is within the C s normal voltage range than all the screenshots look good, extremely good. But they are all at nearly identical SOC of 52% SOC. And a much better way to gauge how good the battery is is by getting screen shots that show data when the C charge bars are at their highest and lowest, to be able to check the battery health.

 

If your 2015 is like our 2018 the USB port is part of the stereo, electrically speaking, and gets its power (and fuse protection) there. The USB socket just has a little pigtail wire off the back that plugs into the back of the stereo.

If it doesn't work.... Congratulations!

Now you have a great excuse to install a modern head unit. The Prius c is one of those rare cars that can fit an enormous variety of aftermarket systems, and it's easy to do.

Ours was 4 days out of the showroom when I installed a nice Sony that can do CarPlay and Android Auto. Haven't looked back.

 

One other thing about the DrPrius screenshots I didn't comment on are the 3 battery temp readings. Those temps of high 80 low 90's are normal during summer up north. So if you took those shots recently I say that those temps are quite high unless the car had been driven for at least an hour or two and you had the heater on.. There are always lots of variables, some more obvious and others a lot less..

 

Good excuse to check/clean the battery cooling fan under the left rear seat.

There are youtubes covering how to thoroughly clean it with a screwdriver and a vacuum cleaner.

 

This was a great post to read. Thanks for everyone's input.

I'm researching the Prius c because I may be buying one in the next few days. Can ya tell me a little more about Dr Prius and/or Car Scanner? What's the best to run to check the hybrid battery's health?

I'm looking at a 2014 Prius c Four w/ 58k miles. Super nice condition. Paint finish looks new. It's had just one owner who kept it very clean inside & out. Regular 5k mile maintenance w/records. No accidents. Steering is still super tight & responsive.

I test drove it for about 40 minutes. 20 mins on the interstate got 48 mpg. 20 mins on city streets & county roads got 54 mpg. I know it's 10 yrs old but it seriously looks excellent, drives great & was driven <6k mi per year.

Ya think it would be a reliable daily for a few years? I had a 2012 Prius Plug-in from 175k til 306k & a 2017 Three Touring from 48k til 130k when it was totaled in Feb. Nothing but regular maintenance, brakes, tires & one wheel bearing on the combined 213k miles so I'm sold on the Prius’ reliability. All the car review sites give the Prius c nearly as good reliability scores,

Thanks for any help!

 

Thanks for this heads up! That's the first thing I noticed in the 2014 Prius c Four I'm looking at. No Apple Car Play or Backup camera. But, ya say it's easy to find replacements?

 

I'm saying it has a space in the dash that can accept a generic double-DIN aftermarket deck with ease and grace. It's really hard to do in some modern cars and impossible in others. But the Prius c is about as easy as it gets for that type of replacement.

That is not the same as a plug-n-play finished unit designed to precisely fit the car. Those are a relatively new phenomenon, and they don't exist for every possible target application. I can't speak for them in the Prius context.

 

Perfect. that's what I thought ya said. thanks.
