      ChapmanF you can probably identify this issue! I have a 2011 Prius and on January 20th of this year, this loud hum noise started http://link.www.ridesharedriver.blog/Prius_hum_noise. That is from a mic on the "Shotgun seat" While I am driving on Interstate 275 in Tampa, FL. The noise is very loud in the car. When I get over to the left or make a left turn the noise goes away.



      Thanks,

      I am having ABS 33-34, (!) 36, VSC 43 just like it..
      Thus I am stealing the feed from the front sensors to feed the rear sensor..
      1. Are front sensor unique? ie different than the rear.. ie is the start up test failing because my front check signal is different that the rear check signal.

      Yeah...no way I'm playing with hot High Voltage. Hence my "interesting" comment.... Thanks.

      You're the PriusChat poster with the greatest technical training. Things you've written have been quite helpful to me in recently years on Gen IIs and Gen III's. Do you know of any a coherent discussion of trickle charging a Prius traction battery using a 300mA/250VDC power supply in the form of a Meanwell LED driver module? Can it be done without removing the traction battery from the vehicle?

        I doubt I've the most technical background; the list is surely longer, but check out Elektroingenieur, fuzzy1, mr_guy_mann, Mr. F, and several others. We don't really know who anybody is or where they work, but those accounts often make well-informed posts.

        As for a 300 mA LED power supply, I think if you search the forums you probably will find threads discussing that or very similar approaches.

      Mr.Chapman, I can't thank you enough for pointing out that water drains down through the back side of those low drain openings that I covered with wire and then down further. Your warning about not blocking that outer drain was very much appreciated, and in fact the foam blocked the drain

      Greetings ChapmanF, I just wanted your input on the possibility of using a EG4 solar inverter advertised to have a 120 to 500 vdc input capacity on 2nd or 3rd gen for home backup power.
      They sell a 6000 watt split phase for 1300 dollars, and a 3000 single phase for only 750, only weighs 18 lbs.
      My question or doubt is whether it would handle the voltage fluctuacion when the ice kicks in. What do you think?

        I'm not familiar with those units. They could be of interest. I left a longer comment on the forum post you made about them.

      My 2002 Prius needs the steering torque calibrated. My scan tool is supposed to do it, but fails. Are there pins on the OBD port I can touch together the magic number of times in the right number of seconds to set it?

        I believe so; see pages DI-457 to DI-459 (in 2001 book, maybe slightly different page numbers in 2002 edition). Have you started a thread about this? Maybe do that, include what trouble codes you have. That way the thread helps other people, they don't have to read my profile messages.

      Is the master brake cylinder, brake actuator, abs pump assembly, the same part with different names ? Thanks

      Thank again for the info and pic, Q- what does the coolant do inside the cat ??
      1. ChapmanF
        ChapmanF
        Nothing. It doesn't go inside the cat. It goes in the exhaust heat recovery exchanger, behind both cats.

      I think I need them. It's getting around 34 mpg at this point which is significantly less than before. Also, do you have contact info for Rich?

      Thanks ChapmanF. I did the drag test, and though it was kind of hard to do on our busy roads, I think I was able to do it right. The only wheel/brake I noticed that had more heat than the others was the rear passenger side. It was by no means on fire, but did have more heat than the other 3 wheels. Any idea what I should check further? I have never done anything to the rear brakes...

      Do you still have the video of you replacing or removing the center console of your 2001 prius? I am looking to replace my MFD display on my 2001. Thanks!

      Door open indicator does not illuminate if any door is open. All door switches check okay. Does ECU-B control the warning indicator. Also dome light does not illuminate when doors open. Dome will work in ON position. I have schematics for 1st Gen vehicles and it appears to show the dome light (in door position) and the door warning indicator control goes through the body computer. Any suggestions appreciated.

      Apparently deleting the spam in my conversations has made it impossible to send messages so I thought this was the way. I will make a copy and get it on the board soon Thanks

      Thanks for all your posts regarding the Gen III ABS/hazard/directionals issue. I just cut the infamous "sky blue wire at terminal 10" and all is well enough. It's people like you that make PriusChat the amazingly helpful forum it is. Thank you.
