Auto-folding mirrors and turn indicators part numbers

Shoot, the problem is with the second set of pinouts.

TLDR: Use everything in the second set of pinouts except the O9/N9 stuff at the end. Use the first set of pinouts for those connectors.

Full story:
I'm guessing I got the second set from the US wiring diagram. My annual subscription ended yesterday, so I can't double-check. Sorry, but it's been about a year since I did everything and I made notes back then for the moment, not for posterity. I think O9/N9 are the names for the 11-pin connectors that need to be replaced if you have the Panoramic View Monitor option.

Long story longer, Toyota uses the 11-pin when the market has PVM or folding mirrors w/ turn signal, but not both. USA/Canada has PVM but not folding/turn, and Mexico has folding/turn but not PVM. Japan and Europe have both, so they get the 16-pin connector(O11/N12).

So the US wiring diagrams(which include all North American cars) have both the US and Mexico ways to wire the 11-pin. I must have used that for some stupid reason when I made up the second list.

When I put together the more recent list for you(the one you put first), I used my notes from 1.5 years ago when I still had access to the Europe wiring diagram with the 16-pin connector(which is the same as the Japan).


This should be the corrected version:

K21 - 10 - Mirror Forward - lavender/pink - supposed to go to a junction connector then off to each door
- Drivers Door - pink <|> OK2 connector in driver footwell/pin 2 <|> green <|> O11 connector near mirror/pin 11
- Pass Door - gray <|> NK1 connector in pass footwell/pin 2 <|> red <|> N12 connector near mirror/pin 11
K21 - 24 - Mirror Reverse - lavender/violet- supposed to go to a junction connector then off to each door
- Drivers Door - sky blue <|> OK2 connector in driver footwell/pin 13 <|> violet <|> O11 connector near mirror/pin 3
- Pass Door - black <|> NK1 connector in pass footwell/pin 13 <|> violet <|> N12 connector near mirror/pin 3
K21 - 25 - Ground - white/black - connect to a ground(can either splice to previous ground or to K21 - pin 13)
K21 - 38 - LH Turn - violet - splice into wire - yellow <|> OK2 connector in driver footwell/pin17 <|> black <|> O11 connector near mirror/pin 16
K21 - 39 - RH Turn - pink - splice into wire - sky blue <|> NK1 connector in pass footwell/pin17 <|> black <|> N12 connector near mirror/pin 16


Sorry about that.

 

K16-28 should be K16-27. Just a typo on that one.

K16-26: MR(brown)
K16-27: MF(violet)


And, sorry, but it's pins 7 and 8 that are grounds, not 7 and 9.
Here's the pinout for the switch:
O13 (switch)

Code:

1    ILL-    Black  
2    VL      Red
3    HR      Blue
4    HL      Lt Blue
5    VR      Black
6    B       Red
7    E       White/Black
8    E       White/Black (new)
9    MF      Lt Blue     (new)
10   MR      Lt Blue     (new)
11   M+      Black
12   ILL+    Red

 

Huh. I must have used my original mirror glass when I did my swap because I never noticed a difference. I still have all the duplicate parts, so I'm going to have to see if there's a difference with the spares I've got.

When you say the colors were different, did you mean they were different from the one I labeled 'Door Side Old' or the one I labeled 'Door Side New'?

Just to be clear, you are doing this to a US spec Prius HEV Limited with the Advanced Tech package, correct?

 

The errors should go away after you plug back in whatever you unplugged. Maybe a power cycle or two and a short drive will be needed. I don't think I needed to actually clear codes even after driving around for a month with no dash.

It's always good practice to disconnect your battery before doing any work. Prevents codes from being thrown at all. (A practice I occasionally forget to do. <sheepish face>)


I'm going to suggest a $95 month-long subscription to TechInfo(if you don't already have one) so you can access the wiring diagrams yourself. I really don't mind helping, but the official wiring diagrams are so much easier to understand if you're a paid user of the site. You can see each entire subsystem at once, move around it, and zoom in wherever needed. You can then select a connector or module and pull up its pinout with just a click. And then another click or two to find its location in the car. Once you learn how Toyota does things, it makes a job like this so, so much easier.

 

Tips for using TIS for something like this:

(I'm assuming Windows/Chrome. I can't guarantee everything will work exactly the same on a Mac/Safari regarding new browser windows opening and stuff like that.)

After you select Prius and 2024 in the pulldown boxes, you press Search. Then select the tab EWD (electronic wiring diagrams).
After the EWD page opens, click anything on the list - it doesn't matter which. That should pop open a new browser window with the EWD.
For the folding mirror function, go to Exterior - Remote Controlled Mirror
For the turn signals, go to Exterior - Turn Signal Indicators (or something like that - I'm doing this from memory)

For the folding mirrors, the parts involved are Main Body ECU, Power Distribution Box Assembly, Mulitplex Master Control Switch, and the left and right mirrors. You can either use the breakout list on the left side of the screen to find them, or just pan across the diagram.

For the turn signals, the parts are the Main Body ECU and/or the PDBA, and the turn signal lights in the mirrors.

If you click on a component or a connector, it will start flashing. If you then go to the bottom right corner of the screen you'll see a pinkish-orange button. Click that and you'll get detailed info on whatever was flashing. You can do more than one part at once, but I like to just do one at a time so I don't mix things up.

On that screen, you'll get info on the pinouts. You can select one pin at a time to see the wire color(s). You'll also see a list of every system that has wires running through the connector. If you select a pin and then click the 'Select Terminals' checkmark and click the button next to it (I forget what it's labeled - maybe search?), then you will see the system(s) involved with that particular pin.

There is also a link called 'Location of Part' or something like that. If you click that, you will get a schematic of the vehicle showing exactly where that part or connector is on the car.


Finally, you'll probably want to spend about $5.50 on an hour's access to Toyota-Tech.eu after you've become familiar with the US TechInfo and the wiring diagram system. The European site can help you with the O11/N12 connector pinouts. After you've paid the 5 euros, you go to Repair, then Electric Wiring Diagrams. Then you select Prius Plug-In, the gen5, then search. Once you open the EWD, it functions exactly like the US TechInfo one. Same menu system, same interface. Just focus in on O11/N12 since that's about all that you won't be able to get on the US site.
