Added MTS/Crawl Control switch to Platinum CrewMax

How certain are you the position switch is can bus? Those diagrams are amazing! thank you. I wish they had better descriptor on the wires. Im not sure why im still invested in this now that they found me a truck with OR haha I just know its gotta be possible

 

Mirrors are tied to can bus so likely this is too.

 

Bummer that this was not as easy as replacing the 4wd module and switch. Did you happen to test if the multi terrain monitor is activated with the new module or do you still just have the normal panoramic view monitor? Would also like to figure out where this functionality resides. we're there any changes to your drive modes with the installation of the new 4wd computer? Thank you all for continuing to try to figure this out.

 

The MTS is working. At list it shows a different screen in the dash board and the option for sand, rock and the rest.
DAC and Crawl not working.
I stopped by another dealer tonight and they had one with Off Road package.
I can see two wires that are coming out from the main harness right on top of rear passenger wheel. One is going to a small box that looks like a vacuum pump or something like that and the other one is going directly to the differential.
It was pretty dark and could not see that well. Will stop by again, to take a better look. .
I don't mind following if I knew that is only parts that you can buy and install but,, I just don'thave a good feeling about it.

 

You're doing the Lord's work - keep it up!

 

Well, no luck, for now. Been spending all day under the treuck taking harness apart. No plug or pins to continue farther from the main harness above passenger rear wheel to the differential. For now, I am taking my losses and ending with a nice looking control switch. The other way MAYBE, to run a separate harness from the 4 WD computer to differential and locking diff switch. Hopefully someone can make this work someday.

 

Is there a way to find the right harness with the vin number ?

 

Will the MTM works?

 

We are all hoping!! But unfortunately it hasn't worked out so easily.

 

I am at a dead end with the harness that my truck have.

 

Is this true? Would you share how it is possible?

 

Curious about swapping out the switch in my Limited.
Do any of you that have done this have pictures of how this shows up on the 'standard' dash when you use the Multi-Terrain Select?
And, now that the snow is here, if you have noticed any change in traction/performance in the new modes?

 

I installed the switch that have the DAC and multi terrain.
I can say that when I put it on deep snow the ECU doesn’t cut the gas as quickly as before. I spin the tires A lot more

 

Hey what’s going on Tundra dudes, got a 2023 tundra platinum 4x4 any update on this topic? Really interested in installing this, I purchased the switch will be installing this weekend, wondering if anyone here has figured out if CRAWL control works?

 

It doesn’t

 

Definitely watching this and hoping for future updates, along with a link to the original part. Just took delivery of my ‘23 Limited without any TRD options or locking diff.
Would love the MTS function if it actually works though!

 

2 mins on google and found this, as the original eBay link was not working for me.

https://parts.lakelandtoyota.com/p/...SSEMBLY--Combination/17127948/849700C010.html

appears to be the correct part, but can the OP or anyone else confirm?

 

I know this is tundra forum but im trying to do same on my tacoma trd sport, purchase modules, harness and ECU and as soon i installed the ECU code error shows rear locker diff “open” i don’t have rear locker but the ECU has this problem , i guess my next step y to purchase only the actuator and see what happens

 

I remember when I bought the ATRAC switch for our 2007 FJ Cruiser that did not come with it. Plugged it in and magically had ATRAC. It did have locker.

Was hoping to find a 2023 Limited with TRD Off Road and all items we wanted but you know how that went. Good work people!

 

Thanks to this thread, I spent on another mod I don't really need lol.

 

Would anyone who has purchased the MTS switch be interested in parting ways with their non-MTS drive mode selector? I have an SR trim truck that does not come with a drive mode switch. Theres a little storage pocket in its place but I pulled it today and confirmed that it does have a harness that the switch would plug into so I’m interested in plugging one in to see what happens.

Any update on the install?

 

Lol. I just found this thread last week...and the drive module just arrived!

The '23 Tundra is my first truck, and I may have gotten a bit carried with mods. Garage is filling up quickly!

 

@virgilus11 It's been a few months since your last post. How is that switch holding up?

 

Plz report back if this works on the SR

 

It did not work, it plugs in and illuminates but the buttons/dial don’t actually do anything.

 

Damn. Thanks for trying tho. We all appreciate it!

 

Forgive me if you covered this somewhere else or have given up. Just found this thread and have been looking into continuing this journey. Pulled plastics on my 22 platinum to get to the plugs on 4wd control ecu and have a look. Was able to get pictures of the plugs and the pins for the most part. Did not see anything labeled A7 as mentioned. Anyone have pictures or diagram of pinouts for this? Also with mention of only 2 pins for actuator, what about signal from locker verifying engagement? My thinking is much along the lines of adding pins if needed and either "fooling" the locker signal or actually finding an oem locker for less than the cost of an appendage. Mts switch is ordered. Waiting to get better info on wiring before purchasing the trd 4wd control ecu. I'd go as far as making a temporary jumper to plug into someones trd locker , with factory platinum 4wd control and if needed the trd 4wd control to see what changes. If we can figure this out I may be willing to cough up the money for the locker.

 

Why not just go aftermarket so you can activate locker in 2wd or 4hi instead of only 4lo?
