I am working on trying to add MTS/Turn-Assist (OTA) to my 2010 LX. I've swapped the skid-control ECU/master cylinder, switch panel, and combination meter (gauge). No error codes/DTC, zero-point calibration all done. I had to repin the skid-control ECU, and run 2 new wires to the switch panel.
I now how 5 speed crawl. When I'm in 4LO and hit crawl, the menu appears, and I can scroll through it. I can do the active data test in techtstream and the CRAWL icon will appear. The problem I have is that neither MTS nor OTA appear. When I switch to 4LO the MTS menu doesn't appear, and when I'm in crawl, the OTA doesn't activate when you hit the button. The icons can be triggered on the dash through techstream, and I know the switch works (bench test).
What I am confused about is that the skid-control communicates the MTS and Turn-Assist to the combination meter/gauge cluster through CAN, just like with CRAWL. I am trying to get smart about CAN, but why would it work perfectly for CRAWL and not MTS/OTA?
I did measure the voltage on the OTA pin. With IG on it should read between 11-14V, and mine reads between 9.9-10.2V. TIS says low voltage means replace the skid-control ECU/master cylinder. I'm worried that the one I got off a wrecked 2013 is in fact shot.
On the off chance that the 4wd ECU plays a roll in MTS, I swapped in a 2013 ($190 and I was already half way across this crap river). No change.
Just wanted to see if anyone had any thoughts of what I should be checking. I just can't believe that the 2 new functions I am adding would be the only things not to work if the skid ECU is communicating via CAN and the other outputs on CAN are working.
So... help??? At least I got to deep clean my console...
