Pin 13 Doesnt pass TIS, cant program new TPMS
My data link connector came with some kind of supplimental wiring or something. I have already emailed Lexus and they told me to kick rocks. the dealership was pretty much the same. My car when I got it had some wire patched into the OBD2 connector and was working fine, but I was having issues with the power so after I fixed that no I have RG fail and I cant program my new tpms sensors using TIS TPMS utlity. All of my wires match the factory colors but Pin 11, 12, and 13. the factory colors are Green, Black, and violet. Mine are Missing, Grey, and Yellow. I do however have two pins coming from the dash not connected to anything but I cant recall where they go and what they are for. one has 2.5-3v and the other is 12v which I used to provide power to the OBD2 or pin 16 since in 16 didnt have power so I bypassed it.
Can anyone provide any assitance here, have a low tire warning is a huge distraction. I have a multimeter and can sort of read wiring diagrams but the delaer wants 210 just to look at it and so far every time I take my car ot anyone else but myself it ends up as a huge debacle
