Ford Repair Questions? Ask a Mechanic for Answers ASAP
Can you comment on whether this can be done with changing the switch and adding the aforementioned wires?
I have connected both side mirrors by attaching pins 16 and 7 together,
The question I have is to which two wires do I pigtail on to the switch?
I am still not able to get this to work- there is a short when I connect the wires that I described earlier. Do you have a recommendation about which wires to connect to on the switch. I see that pins 16 and 7 fold and unfold on the power fold mirrors.
So I connected both ways and as soon as I hit the switch the fuse trips.
If I understand correctly the switch is able to apply power to both fold and unfold, pin 4 on the switch is labeled as such. From every thing I have read it says that pin 6 is the other wire to connect to. I feel like I am missing something Why is the fuse tripping?
Hello and thanks for your question.
Did the vehicle originally come with memory seats and mirrors?
The mirrors need to be wired exactly as the schematics show. The switches are not wired to the motors, they are wired to the drivers seat module (DSM). The DSM controls the motors by applying power and ground to the motors on different wires.
After receiving the signal from the switch, the DSM applies power and ground to the fold motors. It then reverses polarity to the motors to fold them in the opposite direction, making it impossible to hardwire the fold motors to the switch. The switches and switch wiring circuits are not designed to carry the kind of current necessary to operate the motors, they are just low current signal wires. That being said, the mirrors need to be wired exactly as the schematic shows and the wires for powerfold functions should already be present in the harness even if the vehicle did not come equipped with powerfold. The problem you have is the DSM is not configured for powerfold and this feature is not configurable with a scan tool. The module would need to be programmed with as-built data from the same model and year that came equipped with powerfold. I know of no other way to get them to work and have been down this road several times with customers wanting to do the same thing as you.
You need a VIN number for a 2011 F150 that has all the options as yours, including powerfold. Then the dealer needs to download as built data from the Ford website for that VIN. Then the as built data needs to be programmed to the DSM on your vehicle. This will turn on the powerfold capability of the DSM and the mirrors and switches just plug in to the existing harnesses.
So I think that I should just add another switch to the dash to accomplish this. I found a momentary rocker switch which should work. Where do you think I could get the appropriate power in the vicinity of the left side of the dash board?
Also before I do this, do you think the dealer would do what you suggested?
He is wrong. The FMCdealer PTS website is where he needs to go. Enter the VIN and click on the as - built tab in the oasis dropdown. Ask to speak to a tech and bypass the advisor, most of them are not technically savvy - thats why their service advisors. Click on screen shot below, this is proof it can be done as long as you have a VIN.
I finally got the dealer to try to load a different VIN in to the dsm- They said that when they did that all of the lights on the dash lit up. Is there anything I can tell them to try?
Kenny- They are still having trouble with loading this config in to the dsm--Would you be willing to to talk to Tim (one of the techs) at my dealer?
Ok- I understand-
So they wanted to confirm that this should be loaded in to the dsm rather than the bcm.
And if so, I should ask them to only load the data for the dsm?
So I just got off the phone with the service tech- and he now tells me that my truck does not have a dsm. Is that possible? He says that I only have 2 of the 3 modules under the seat.
My VIN is 1FTFW1E67BFA29801
He shouldn't even need to look under the seat, it will show up on the IDS network test.
Here is the bill of material for your VIN with the DSM shown.
Attachments are only available to registered users.
Here is the as built data from the DSM right from your VIN number
When they ran the test everything passed. But it was not listed in the "as built" tab.
When we compared what you printed for dsm specifaications and what they downloaded from the example vin there is one line that is different which I think needs to be loaded, we just cant get to that screen.
Was the DSM listed in the modules that passed?
Have the tech perform a PMI on the DSM. When asked to turn the key on leave it off and click the tick. It might ask him several times and eventually he should get a message that says the module is blank. Once that message appears the following screens should allow him to enter as built manually. This is forcing as built. The tech should really know this stuff.....no offense but these questions are showing a lack of experience
They tried this a couple of times and it does not come up as "blank" He says that it goes to a screen that says successfully loaded.
I am going to go there again tomorrow and go through the motions with them. If we can not get it to go- Do you have any recommendations for dealers in central New Jersey? Are you close by?
Thanks again for all of the advice so far.
So I went one last time and did the procedure with the tech, like you suggested and it did reprogram automatically with the key in the off position. Again- I was only observing- but that is what it looked like. It did not give the possibility to force the as built data.
Now before I go to the next dealer I was wondering if you could confirm the line in the dsm that needs changing-
The example vin has the following code difference (in line 1) in the DSM-
Mine is 744-01-01 F840 85
Example 744-01-01 FC40 89
All of the other lines are the same.
Do you think that will be the one that will control the mirrors?
I will start calling other dealerships and asking for the programming tech.
It worked! I went to another dealer and they were able to get it programmed. The mirrors are now folding in and out.
Thanks for all of your help on this.
