Terrain management upgrade?

[dmeyer302]

Yes... I've done a lot of comparing...

This is what I have come up (Not VERIFIED).

It looks like

Instrument Cluster:
720-10-01 1004 1000 is Trail Control in combination with.. (1000 1000 is non Trail Control)


ABS:
760-02-01 0505 0A03 is FX4 equipped (0105 0A03 is without)
760-02-02 x4xx 4 is SuperCab, 5 is SuperCrew
760-02-02 xxx3 3 is FX4 equipped, 2 is without
760-03-01 xxx7 still working on this one... But it seems that EVEN is no TC and ODD has TC Number Range from 4 to 7
IE: 4 No TC, 5 has TC, 6 No TC, 7 has TC (Loaded). Some group 302a have even and some have odd.

I did this comparing all of the same year vehicles (2020) (which is what I have). Other years may vary.

You’re doing the Lord’s work.

I have already installed the TC button in hopes that someone would figure this out. If you get above 90% confidence I would take one for the team and try this out.

Since I am only looking at data from about 20 2020's

I would try:

720-10-01 You should see 1000 1000 0038 Change to 1004 1000 005C (XLT and LARIAT ONLY)
That should enable the cluster.

760-03-01 will have a EVEN number in it. Make it 1 higher and should be an ODD # (so a 0004 becomes 0005) 0006 becomes 0007 etc (Checksums are 0005 70 and 0007 72)
This should enable the TC.

However I believe you also need the FX4 package which would be
760-02-01 and should have 0105 0A03 027F in it. which would be changed to 0505 0A03 0284

760-02-02 is your body style (Crew vs Cab) but the last number seems to change with the TC/FX4 option. So a 402 would be a SuperCab and a 502 would be a SuperCrew that would change to a 403 or 503 depending on the Cab.

If you want to give that a go.

NOTE: This is a guess purely based on looking up VIN's on CARS.COM and decoding them. But I am attempting to do the same thing. If your numbers don't match, please don't proceed. I only did 2020 models and the model year and the data may have changed with the model year.

I’m told by reliable sources that this feature is in the tcm and not available if not equipped. About 2 years ago we all went through a bunch of asbuilt files and several users made changes to their trucks. Nobody was successful.

check out saeb.net for more info.

Thanks. It will be next week before I can get the OBD adapter from my dad. I’ll report back.

I tried it tonight... Definitely CLOSE

It complains about the BRAKES and ADVANCETRAC errors. So there must be some missing hardware, additional settings that also needs to be changed.

Ummm if you mean the trail control no one has been able to figre it out

It would be nice to compare notes with others on this. I noticed on the F-150 there is a missing wire that must be ran. Does anyone have access to a wiring diagram for a 2020 ranger?

I've not given up on this. I am going through 5 vehicles of the same year as mine to compare the differences via AsBuild Hacker (After editing the XML for the Ranger).

Wondering if some of the other options can be added as well (IE: rain sensing wipers).

Not wanting to duplicate what others have done..

There seems to be 2 features that I am trying to install. I have the button for the Trail Control I believe works with the HDC feature.

According to the manual (above) this is the sequence. The GWM Model (716) is exactly the same between trucks. So no changes there. So has anyone put all of the 760 (ABS) and 720 (IPC) blocks from a KNOWN AS-BUILT truck with these features in them?

Nobody I’ve seen has done this. That said don’t overwrite the vin which is usually in the first few blocks.

hill decent control is replace by trail control on fx4 trucks.

I have NOT tried replacing all of the IPC blocks, But in the 760 ABS Module there are just 7 blocks that differ: (Mine in the Left), TC on the Right (2020 Lariat, SuperCab)

In the IPC there are 10 Blocks that differ... But this vehicle also has additional options
(Mine on the Left vs TC equipped on the Right)

Again haven't tried them all, but these are the screens that I get.

Yes sorry should have mentioned that, I have identified the VIN in the 760 ABS module which ends @ 760-02-01 (checksum)

(RED = VIN in ASCII (HEX))

Instrument Cluster:
720-10-01 1004 1000 is Trail Control in combination with.. (1000 1000 is non Trail Control)

ABS:
760-02-01 0505 0A03 is FX4 equipped (0105 0A03 is without)
760-02-02 x4xx 4 is SuperCab, 5 is SuperCrew
760-02-02 xxx3 3 is FX4 equipped, 2 is without
760-03-01 xxx7 still working on this one... But it seems that EVEN is no TC and ODD has TC Number Range from 4 to 7
IE: 4 No TC, 5 has TC, 6 No TC, 7 has TC (Loaded). Some group 302a have even and some have odd.

Sounds like a solid theory. I was told that the part number would be same, but the flash would be different. Who knows though, it seems like you just change them and then cycle through the last one with odd numbers until something works.

main reason I gave up is my truck is an fx4 and my dads is not, but I didn’t want to be testing stuff on his truck that I couldn’t guarantee wouldn’t brick something.

I would have preferred a FX4 equipped truck, but I bought mine in 2020 end of year and got a Lariat for the XLT price. It was a lost leader. Now cracking this code is just a game. Do I need it? No, Will I ever use it? No (I wanted the extended cab to have the longer 6' bed, and knew I wanted the LED headlights and Leather. The rest I didn't really care). It's not my daily driver either.

Can confirm this

 

[Illking]

hi, without reading all 40 pages of this thread just wanted to lazily ask first. Can a XL w/101a gain terrain management & trail control by ordering this switch and using forscan?

Terrain management and Trail Control are two separate things but tied to same system. I think you’re referring to Terrain Management or TM that is part of the Hi-Lo 4x switch. If so the answer is yes to your question.
