Hi all, currently working on a t300 throwinga 12-23 code. Replaced right handle, worked good for a day. Now it's up to it's shenanigans again. Press the aux button, auxiliaries function on their own, without touching the right handle, for a few seconds then turn off. Any ideas?
Did you have to repin the connections or was it plug and play? If handle is new and all wiring is good it would have to be the auxiliary controller.
Just because it's new doesn't mean it's working correctly. The code is for the paddle switch out of neutral. If you have a local dealer they can put it on the computer and see the position of the switch and probably diagnose your issue instead of throwing time and money at it
My co worker repinned the plug when he installed the new handle. It worked good for a day, now it's doing the same thing again. As you said, I threw the towel in and had the customer take it to the dealer.
