4th Gen Expy FORScan Modifications

[East-TN]

I just took delivery of my 2018 Expedition Limited MAX this morning and by noon, I was already playing around with FORScan. Here is what I have found works so far.

Everything listed below has been confirmed working. If you find something you think is of interest that you have confirmed working, please feel free to add it here so we can build a google doc of all the available modifications.

Here is what I've come up with so far:

BdyCM    726-41-02    xxx0 xxxx xxxx    Disable No Key Present Double Honk

BdyCM    726-27-01    xxxx xxx0 xxxx    Enable Fogs On w/ LED headlamps

BdyCM    726-48-02    x0xx xxxx xxxx    Disable Auto Start Stop

APIM     7D0-01-01    xxxx xxxx xExx    Enable On-Screen H/C Seat Buttons

APIM     7D0-01-01    9xxx xxxx xxxx    Disable Sirius As Audio Source

APIM     7D0-02-01    5753 xxxx xxxx    Data Entry While Vehicle Moving

At this time, whenever I try to write anything to the IPC or DDM/PDM, I receive a "Service procedure has been interrupted." error so I will be sending log files to the FORScan people to see if they can resolve the issue.

@rcompart...did you change 4 bits for the Navigation in Motion line on the APIM (7D0-02-01)...or did you change the line to the following:

7D0-02-01 x7xx xxxx xxxx

Any other 2018 FORScan changes you've uncovered? It looks like the 2018 Expy is almost line-for-line the same as the 2015-2018 F150 codes...is this what you are finding?

Thanks.

6 or a 7 in the ? bit allows 3 flashes...see below for the entire code:

Turn Signals - Lane Change Flashes SCCM 724-01-01 xxxx x?xx xx

Change ? to: 0-3 1 Flash, 4-5 2 Flashes, 6-7 3 Flashes, 8-9 4 Flashes, A-B 5 Flashes, C-D 6 Flashes, E-F 7 Flashes

Yes, that part is obvious. However if you read through the forscan thread, you will find the difference between the two values is how the turn signal turns itself off after a turn. one value will continue to blink until cancelled with the stick. And from the user who reported that, and the spreadsheet values, generally that is controlled bu the 1 bit. In their case (F150) the 1 bit had to be off. In my case, that one bit is ON. hence difference.
So i chose just to increment the value without changing the 1 bit.

Also note with the 2018, writes to the IPC module fail. This is a known issue, with no resolution yet. (per forscan developers)

I'm not sure I follow...which 1 bit are you referring to?

 

[rcompart]

Only changed the 2nd hex value. You lose the speed limit sign but get a circle with a red outline in its place. Still in MPH though so nothing really lost.

The 2017 F150 and the 2918 Expy are pretty similar and what can be changed is much like that in the F150. You are correct about the IPC and DDM/PDM in that they are something different and cannot be modified at this time. I got a beta back in December but it still didn’t rectify the issues with the modules I was unable to write to.

If that's the case I bet it's doing more than allowing navigation entry while driving… sounds like you're setting it a European locale, as that's what speed limit signs look like over there.

I'm not sure I follow...which 1 bit are you referring to?

the single hex digit is 4 binary bits.
xxxx
8421

the "1" bit is simply the right most bit, followed by the 2 4 and 8 bits. all bits on = 15 (F), all bits off = 0 (0)

my initial value was 7 (0111), and i went to 9 (1001), leaving the last bit in the on position.

Edited: 7 to 9 (not 5 to 7 oops)

Yup, and there are 10 kinds of people. LOL

Great explanation. But what was the comment about the two different effects of ‘6 or 7’ for the value you had? I haven’t heard the different setting may prevent the turn signal from turning off...can you elaborate what you mean? Thanks

Thanks. I PM'd the poster to see if he resolved his issue...I had not heard of that condition before...thanks for mentioning it.

it was talked about somewhere earlier in the thread too, i dont recall exactly where, and it's a lot to search through. He resolved by changing the value between 9 and 8. I guess that "turn signal always on until you turn it off" is a feature somewhere in the world, although i can't imagine why.

I've updated this spreadsheet with some 2018 info:

Added PowerPoint Timeout - allows you to control when your 12v Power Point will turn off
Added Stereo Extended Play (Drive-In Movie Mode)
Sync 3 Startup Screen Animations

Added Auto Relock - Got this from the F150 sheet, can anyone try this feature (relocks your doors if you press unlock on your Fob, but don't open any door within 45 seconds)

Added Bluetooth Pairing Name Choices

Let me know if there are any errors or if you can confirm any line(s).

Thanks.

Now with the keys always in my pocket or clipped to my belt, I am scared that I will walk away from the vehicle unintentionally forgetting to turn it off.

I have a Hybrid Honda that does not alert if you exit the vehicle while left on. It is most often in EV mode when I pull into the attached garage and completely silent as I walk away. I could see how the gas engine would come on a few minutes later in the closed garage potentially filing the house with CO. It's so easy for us to be distracted with other things now, while the double honk may annoy some and I agree it's annoying, but probably something the lawyers see as a potential lawsuit if Ford didn't sell the car with it working.

BMWs don't do this, in fact I can even lock the car from the outside with key in pocket and leave running GREAT feature for running in to store on freezing cold jersey shore winter day (i know not very GREEN), MB gongs incessantly inside the car if the key is removed and car left running unless the car door is open then OK, only way wife and kids can still watch movies when I go to store with them and forget to leave her key in car.

Different lawyers I guess.

I just purchased cabling and downloaded software for FORscan for my 2018 Expy. Is there a way to default auto start/stop to off with the ability to turn on from the dash board button. So when you turn it on the auto start/stop is lit “OFF” as the default and it I choose to enable it I can simply hit the button to turn it on. Next ignition cycle it defaults back to “OFF”. There are times when it would come in handy but where I live I really don’t need that as a constant on.

I had the same question when i started looking into it. The only way to do what you want is to hard wire a switch into the back of the auto stop switch (other forums cover how to short the switch with a little wire.. basically you install a second switch on that wire, which allows you to turn on and off your always off switch. (hope that made sense)

with Forscan, your only option is basically nuke the feature all together. As was explained to me, the value you are toggling is one of many checks that the auto start stop looks at. as the check fails, the engine doesn't stop.

I to would like the option to selectively enable the auto stop (like sitting in drive through lines, etc..), but given the choices, i choose to idle.

That is too bad. I guess switched off it is. Hopefully someone smarter than me can figure it out. I wonder why Ford didn’t give an option to control that feature a little more. I can set up mood,lights but not control engine functions.

This video of a guy with a Raptor shows how he disabled auto start/stop by removing disconnecting a cable from under the dash. Seems to work and I am going to try it and report any other issues.


What he unhooks maybe just the auto start/stop ignition control wires between the button and the starter module or something to that effect. I’m going to try it and see what I think. If it works it might be a satisfactory work around to easily disable and reenable at will without reprogramming or taking the dash apart.

EDIT- I tried it out and it does effectively disable the auto start/stop function. A side effect is that the blinkers have a more rapid blinking and audible alert, like twice as fast, but the external lights remain at normal speed. No other functions seem to have been affected. Don’t know for sure is Hill Assist or Traction Control is effected. Maybe someone with more expertise can chime in.

I plugged the wires back in and did a full vehicle restart. Normal operation auto start/stop returned. It did take a couple of full stops for it to start working but it worked. I had it unplugged for,about 30 miles then plugged it back in. Unplugged it again for a mile or two and plugged it back in with the resumption of the AS/S. “AS/S”. Hehehehehe
