Hi all,
I have a 2008 highlander sport with a rosen nav. unit, and the backup camera is connected to the MID above the rosen unit.
I just had the a/c evaporator unit replaced and the tech said he couldn't get the MID unit to work, always blowing a fuse when grounding to radio. When I got the car I checked it out and found that there were TWO of the same E11 connectors in the dash and he had connected the wrong one to the MID (one with only 8 leads in the 16 pin E11 connector), the other connector was just unconnected to anything hanging in the bottom of the dash. When I plugged in the correct (14 leads in the 16 Pin E11 connector) all the functions of the MID worked (door sensors, temp, clock, gas milage) even the backup camera mode, except no picture. I checked the voltage at the camera and it is only getting 4.8 volts.
My questions are:
)What is the other 8 lead E11 connector for? Perhaps the other type of mid that is clock only with push buttons for adjustment?

)Is it possible that the a/c tech when using the wrong connector either blew the camera or damaged something in the MID to not put out 6 volts?

)Will the camera work with only 5 volts (4.8)? And can the camera work with 12 volts without damaging it?

I did hook up a separate video feed to the video leads at the camera location and was able to get video on the MID (when in reverse) and also got another (used) backup cam but got no picture leading me to think that it's not enough voltage to run the cam.
It's a confounding situation that I know must have a solution but I'm not finding it yet.

Any help or thoughts would be greatly appreciated.
Thanks

Take a look at this post for E11 connector identification. AFAIK, you need ~6V to work, I had tried to use the PAC RP4.2-TY11 controller to power up the factory camera, however, its voltage output was only 5.1V, thus there was no image. I don't think you'd want to feed 12V to it, may be check both the 10A ECU-B and 7.5A GAUGE NO. 2 fuses.

Thanks for your reply. I will check out that other post. I did check actually all the fuses, and all are good. I'm wondering if the other plug which was plugged in had damaged the MID power out to the camera making is give less than the 6 volts it needs. I'd rather not replace the MID as everything else works on it. I did take a look at the other post you mentioned. I may just tap off of the reverse light and add a 12 volt to 6 volt regulator converter. When I use another video source (a camcorder) and tap into video leads at of harness at the back up camera, I do get video on the MID. Another auto Rubik's cube.

It does seem like the MFD was semi-damaged when the wrong plug was connected to it. If you're brave enough to open it up and see if any components along pin 12 (CA+, camera power) or pin 4 (CGND, camera power ground) may have some burned mark, it may be replaceable. Otherwise, there are other MFD on eBay (83910-0E050) that you can try.

I did do a visual of the inside of the MFD and didn't see any apparent damage. Then I checked the camera power output and only got about 4 volts, so short of reflowing the circuit board, I ordered a used MFD unit and will give that a try. I'll post the outcome.
Thanks for the help

I ended up getting a used MFD unit and problem solved. The wrong connector must have shorted or done something to the output voltage of the mdf to the camera. At least it's solve now.
Thanks againg for the help.
