Electrical component not recognised by Toyota Service

did you buy the car new? maybe a previous owner added it.

where in the world are you? they don't test the battery over here.

 

so either they haven't been testing it, or some moron just noticed.

 

Can’t it be both?

 

Looks like something lockpick would sell.

Go to coastaltech.com they sell mods for a Prius. One is an ev button the other is a mod to power up the cig lighter plug up front all the time the other is an auto door lock.

Is the power outlet plug hot even with car off?

Do the doors all lock above 15 miles an hour? I like that one. Should have installed that one lol.

If not I have no idea. It’s in that area so they could tap power off the fuse box right there at the kick panel.
Pull the power wire off that’s piggy backing a fuse after taking a pic of where it went and then see what doesn’t work.

Good luck.

 

Ed , Coastal Technologies - Web Designers, Ecommerce, Marketing Consulting, Online Marketer | Upper Montclair NJ, is now a webpage design service....
However, I did a search, try here, MYGIG

I would have to agree, try to trace where the added wires go, have a copy of the electrical schematic to ID landing points and wire color codes, or yeah, pull the +12, see what stops working!

 

TOYOTA LOCKPICKS

 

It is certainly some after market addition, not a factory item. The construction style doesn't match up with anything a car maker would put in there this century.

I'm seeing an exposed old-fashioned TO-220 IC with a common good-sized heatsink, typically of a linear voltage regulator. (First guess: it reduces the 12V power input down to 5V for the other components.) Another IC, probably a standard old-fashioned DIP package, is on the circuit board hidden and somewhat protected under the gray heatshrink plastic.

 

I thought maybe an amp for a high powered stereo system, just a guess.

Much too small for that. A couple watts at most.

 

NSA, Maybe CIA? The government is watching you man

 

Their stuff is vastly more compact, protected, and hidden than this 1970-80's era stuff.

 

I agree like a LM reg only reason a reg would be in there is if they need 5 volts somewhere.
I have never seen any lockpick mod with an outboard 5 volt reg all there chips are 12 volts.
I would pull its B+ connection at the kick panel fuse block and see what you lose. Easy to find that lead it’s probably piggy backed on top of a fuse in that block. Looks like a butch job it was just pushed up under the valence panel. Should only 3 wires to it b+ and a ground and a power lead to wherever it’s going. What’s really weird is the dealer detected it with techstream.

Interesting stuff though.

 

Were does it say that?

What is weird though, is that they claim they can't do the HHC because of it. I wonder what stops them doing it?

 

How did the dealer find it then? Did it fall out from being stuffed up in the dash the op never mentioned it just says they refused to test the system because of it.
The more I look at it may be a small audio amp output IC like in a car stereo.
Maybe the OP can get th3 part number off that IC that will tell us what it is.
His pictures don’t show how many wires come out of it.

 

Get the part number off it I can tell you in 10 seconds what it is. It’s the white letters on the black transistor.
And your right it sure isn’t connected to the hybrid system.
