Added MTS/Crawl Control switch to Platinum CrewMax

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?

 

I hear you. And will go this route if nothing else. Mostly just being stubborn and would like an oem option. Huge fan of not splicing or cutting as little as possible when building a vehicle. Especially with what the truck cost. And if we can get to that point, surely we can add a 4hi bypass to the circuit.

 

so i'm a little confused...is there any benefit to swapping out JUST the MTS/Crawl control switch on a NON-offroad model?
To clarify, the truck only has the drive mode and tow/haul selector.

 

New to forum, my 2023 Limited non Off Road package, installed MTS/Crawl switch and nothing happened. Might need the MTS module like my gx460 when adding this. From my research, the MTS switch will work on higher trim models with the hybrid motor to get MTS.

 

So I have a 23 Tundra Platinum and decided to try the switch out. Installed easy and everything lights up even shows the MTS modes on the Digital dash. I have not confirmed if it actually changes anything in the drivetrain though. It will definitely not have the crawl control since the platinum doesn't have the factory rear locker. Ill try to up date once I get out and try it in 4wd.

 

Did you have to take the center console apart to install the switch or just pry the switch out with the pry tool like some members had done?

 

It was super easy and you dont have to remove any of the center console. I just used a trim tool to pop the module out. The wires on mine were super short so it was a little tight to unplug it and plug the new one back in but overall maybe 5min job.

 

Sorry for the late reply. As I mentioned earlier, the multi terrain looks like is working but not the Crawl or DAC

 

On a standard sr5 sx does the addition of the MTS controller prompt a visual of the sand, snow, mud, modes on the dash?

 

Yes

 

84970-0C010. Put this in my 23 tundra sr. It lights up when the interior lights are on but doesn’t seem to do anything else. Just wondering if any of you have any advice on what to do next.

 

Will this mess with any of my factory options. I have avs, and want to make sure if I switch the switch, my comfort, sport+, etc will work fine

 

I have the platinum trim with the AVS and all the driving modes still work. Comfort, sport +, custom, eco etc.

For the question on the SR trim, I believe a prior post indicated that the switch did not activate the MTS. Make sure you try putting the truck into 4H or 4L first then try hitting the MTS button.

 

Yeah I’m not getting anything to come up whether in 4wh or L. It lights up with the rest of the ambient lighting but that is all. When I ordered the part it even said it was compatible with the SR trim. Not sure if I’m missing another component or it needs programmed.

 

After changing this out I got a cel any ideas why/how to clear it?

 

Would love to know how this turns out. Have an SR myself. Wonder if it’s software locked or there’s mechanical components that aren’t installed

 

I ordered the next control switch down trim wise. I believe it only has mode and tow/haul. The parts dept said I could hook it up in the parking lot and if it didn’t work I could box it up and return in. I’ll keep you posted!

 

what do you currently have in your truck?

 

Stock it comes with a change dish where the control switch is. But when you pull it out the wiring plug is attached to it.

 

so you've got an SR I assume?

 

Yes, 23 SR.

 

Keep us updated

 

Will keep you posted. Will be a couple weeks till I get it picked up.

 

I ordered the 84970-0C010 MTS /DAC Crawl switch last week. It arrived today and was a 5-minute install. Only the Drive Mode and Tow Haul light up. All switches illuminate when I turn the lights on. I have a 2022 SR5 4X4 non-TRD.

 

Put it in 4x4 then try mts.

 

Same question

 

I put it in 4h & 4l, nothing.
