Adding Co-Pilot Assist 2.0 with Forscan?

[superfordman]

So did some more playing around this evening, changed some settings to better match what Jesse sent me and mainly disabled a few things I had enabled in trying to make IACC work and...

I can get IACC to work, but only for about 90 seconds after I turn my truck on and get going. I can seriously almost time it down to the second, I should just for kicks, but after that time it errors out, saying TSR not available on the IPC, then it pretty much won't work at all for the rest of that key cycle. IACC works great and like it should up until that point, this evening it took me from 35, to 45, 45 again, then up to 65, then errored out shortly after. So I definitely have something weird going on. I wanted to try everything under the sun until I subscribed to connected nav again, not that I have any issues doing so, just wanted to try and cover every base before I tried that (almost) last resort at this point.

Going to get subscriped again for it right now then play around with it tomorrow and update on what I find, fingers crossed!

On another note though, ACC and lane centering have been working frickin flawlessly since I got them working last week! Love both of them and can't see myself getting a vehicle without either moving forward. Using the good ole ankle weight trick, this thing keep it between the mayo and mustard no problem pretty much everywhere I go.

I don't think connected nav is the issue. I don't have it and I got it working today and didn't have any errors on TSR (once I figured out that I was missing a setting causing the whole thing to kick off). Only drove it about 20 minutes though, so we'll see if it's truly working over the next week. The radar does seem to have a very narrow beam in front of the car and the acceleration/deceleration ACC commands is pretty aggressive. I'm glad I got it working though. Some lessons learned:

On a Powerboost that pedestrian speaker bracket is very in the way when removing the bumper and super sucks to move out of the way. I eventually removed the bolt holding the bracket to the top of the frame, pulled out the push pin up there, and ended up cutting the push pin on the side of the bracket nearest the intercooler. I replaced that pin with a bolt so it's easier to remove if needed in the future (like when I decide I need forward sensors, front BLIS, active park assist, etc...)

When I plugged the CCM in and tried to see it in Forscan nothing showed up. I needed to change the following in the IPMA to have it give power and/or relay the CAN bus to/from the CCM:

IPMA

706-02-02

When I first tested it ACC would enable then immediately disable. IPMA and IPC had DTCs for invalid config which led me to take another look through the as builts from my reference trucks where I identified an IPC change I missed.

Also, the CCM calibration happens above 31mph so keep that in mind when you go to calibrate it.

Awesome work!

Yes, I found that out today unfortunately that connected nav has nothing to do with it, as my truck acted no different today with it enabled, 120 seconds, almost to the dot after start up, TSR throws an error and doesn't work. So once I have some time I need to go back through everything and make sure I don't have something messed up someplace. I did discover that cold booting the APIM on the fly brings back on for another 120 second round again, so it must being something in there I have possibly.

You're right on with that IPMA change, I think I already had it enabled when I got my new one working so no issues there getting it to show up.

SUCCESS!!! I finally got TRS fully functional after @Jesse-Infotainment gave me a tip which then lead me to look at another value just down the line from it, and the combination of the two seemed to do the trick! Did some testing this afternoon and my TRS/IACC is fully functional like it should be! Here are the two I changed today which, the second of which I never changed until today after doing some more comparisons with equipped trucks.

The next and final test will be to copy my advanced IPMA config to my original basic IPMA to see if everything still works just the same. If so, then anyone with basic lane keep assist can add ACC, lane centering, and IACC with just a simple CCM pretty much. I have a buddy with a 300A in which we are going to try to add everything to so will see how that goes as well. I have a pretty good handle on everything now, so once I can verify all the values that need changed for certain, I'll try to start a new thread with everything in detail.

Superfordman, obviously your skills are above that of the average f150 owner. That being said, is this something that could realistically be done by a normal owner at home? or should we give up hope if our truck didn't come with 360 assist?

Also, how did you add the missing buttons to the steering wheel

Thanks in advance

 

[superfordman]

Ha thanks, just like to mess with things more than the average person I guess and I can't leave sh*t alone, @Jesse-Infotainment and @JaHoova are right there with me.

Realistically this is a very easy add, I'd give it a maybe 3/5 on a difficulty scale, with 80% of the work being done in Forscan, so if you are fluent and good with it, or have a buddy that is, you'd be set. You just need to add the front radar sensor and then then depending on your trim level, a harness to connect it. A LOT of changes, tinkering, and calibrations need done in Forscan to enable everything, but if you take the time to work through it works just like it did if the truck was built with it.

Currently I haven't even added the steering wheel buttons. The ACC distance is currently set to 3/4 bars on my truck, which this can be modified in Forscan as well, and I haven't had a desire to change it yet. Mainly due to where I drive its just right. I do have the correct switch to put in there if I get bored some day, which I might, but works all the same without it as well.

Thanks for replying!

I struggled to install amber LEDs in my grill haha, so I'm sure I lack the requisite skill but I really want to get ACC and lane centering.

Are the forscan changes different per trim? or worse unique per vehicle?

Per vehicle.

I guess that's curtains for me then lol

Unless one of you happen to live in FL and want to make a few bucks helping a guy out.

We help each other out daily on here. Remotely. We all pitch in. We can look and tell you what you would need to change. It’s not like that at all.
I can even remote in and do things if had to . I do it all the time for guys on here.

That's really awesome that you're willing to help others out.
I give you a lot of credit as this level of kindness is unfortunately becoming more rare nowadays.

What should I do to get started? I have a '22 XLT high. Do I just need the CCM and a forscan adapter?

Thanks again for everything!

Yeah the CCM part number you would need is complete with the bracket and all

If you buy the mongoose you can use it for the Forscan also

You probably will also want a new wiring harness for the bumper unless you want to go the Jesse route and make your own. Since you have the XLT 302A the CCM wiring is probably present to the front bumper connector already making the wiring harness the simplest option. This thread has a good discussion of what part numbers apply but always cross check those yourself/with your parts department as those aren’t refundable. There is a useful tool in the links on the big ECU thread called as built explorer that lets you compare as-builts from different vins. That and the massive Forscan Google doc is how I found the stuff to enable ACC. One of these days I need to write up my changes. The key if you’ve never looked at this before is that while the specific bit locations in Forscan to change should be mostly the same across trucks the values will be specific to to your vehicle based on engine,packages,wheelbase, etc. it’s really fascinating once you get into it and becomes a little addictive.

I could really see how chasing the results on forscan could be rewarding in and of itself. Back in the day I would root and rom my android phone and getting that deep into the system beyond what the typical user was ever supposed to do was kinda mind blowing. Of course, losing a $1,000 phone is nothing compared to messing up my sole means of transportation lol.

I'll try to get my hands on the part, which if I followed this thread correctly should #9E731, right? Honestly the forscan stuff at the moment seems more intimidating than installing the physical installation, but there are other things I want to change via forscan too like the time before the usb ports go off after the ignition is turned off - so I guess it really makes sense to try and learn forscan.

Quick question - on a CRV I had it would constantly bug you to put your hands on the wheel (really move the wheel) every 6 seconds. Is there anyway to eliminate that or greatly increase the time in forscan?

 

[JaHoova]

It's like 12-13 seconds for me. And I don't know of a way to change that. As for part numbers the suffix is super important. One of the 9E731s is just the radar and another is the whole assembly with the bracket. Doesn't include the screws you need for the bracket though... Best bet is to find a truck with the feature you're trying to add in the same or similar trim level and a friendly parts department. Then compare what is on your truck to the one you are trying to match. That's how I found my numbers- I looked at a few trucks with ACC and compared part numbers. Then with that reference truck VIN you have something to compare on the as-built explorer for the Forscan mod.
