Replace mfd 86110-47230 with 86110-47081?

@ChapmanF probably has the answer. Many posts about the need to match part numbers in PC. Also even if the new one is not compatible hold on to it and trade it for one that is.

 

Member ITBland did a lot of work figuring out things like and posted in this thread, among others:

Will 86110-47230 work instead of 86110-47081 in 2005 Base Model | Post #2

 

@TMR-JWAP has harnesses for the two styles so he can bench test that they at least power up, so could likely direct you to which pins to apply power so you could at least test that.

 

NOTE: The 47081 is a downgrade! It has lower resolution and does not support rear camera.
No bluetooth etc ...

The connector is the same but not pin-pin compatible, there are about 6 wires that have to be moved.
Look up MFD upgrade, there is a list/diagram in the posts.

Best to find another 47230...big can of worms...

I upgraded from a 47081 to a 47210.
Also upgraded the right/left side instrument cluster.
Had to remove and dump the ODO eeprom.
Texas Hybrid converted the data. Then I flashed the eeprom and reinstalled it.
Also upgraded the capacitors that tend to fail in the cluster display while it was apart.

 

Photos of my test plugs. As you can probably see on the white tag attached to the 47230 model, I accidentally plugged in the 47081 test plug and the 47230 popped and smoked. I plugged it in and then connected the clamps to a 12v battery, and poof, lol. I have not yet mistakenly plugged in the other way (230 plug into a 081 socket, so I'm not sure if it will also pop and smoke). I've included photos that show the test plug along with the oem harness on each model. You can see the wire colors are the same between models but locations of the wires are different. More than one wire gets power, so all the wires that need + are clipped together and all the ones that need - are clipped together. Don't know why the photos rotated, but also don't know how to correct it. Sry about any future neck aches, lol..


47081---green, black, gray, yellow (+) and brown, white with black stripe are (-)

47230---green, black, yellow, gray are (+) and brown, white are (-)

 

Keep in mind, that the plug I use to power up each MFD is 100% physically able to plug into the other model, but as far as I know, if no power is applied, there should be no problem. The middle plug/socket on each model is 100% NOT able to plug into the other model. There is a huge size difference in those plugs.

So, if the customer had the car turned off to pull the dash apart, they probably realized they screwed up when they tried to plug in the middle one. At that point, they likely gave up and backed out of the swap job. If so, it's likely power was never applied to it.

 

I do not know as fact, whether any pins have power on them when car is off.

 

Very likely in the same condition as when you shipped it. When they go poof, they really go poof and nothing works.

 

I wish I could give you some advice, but I have practically zero experience with the Gen 3s, other than building some HV batteries. all my exp is the Gen 2 and some Gen 1.

 

It all depends on what failed, most likely if you don't have the dreaded screen fog, its not hard at all to replace the boards inside the unit, I have 3, one nav, one no nav, and one JBL nav.. all share basically the same power boards and LCD exciter.. I got lucky and found a couple "dead" units at local yards and scrapped for parts and bezels.. I was able to fix 2/3 with just swapping the power board, unfortunately my main board for the 30 was unable to pretend to have a chance.. the 81 is definitely different and is not a match in a couple ways..
