Glad it worked Ralph. Sorry for the unclear instructions.
I have a gt48xlsi with the same problem. what worked for was this. sit on seat, push 1,2,3 (3 times), then push 1, then push 1 and 3 together and hold for approx. 3 seconds. this tuned the to flashing green and evidently reset the switch. I was then able to change to code. This came from my dealer who got it from his factory rep. Evidently this is a brand new service bulletin for 2015 model tractors that wasn't even posted yet for my dealer to see. Good Luck.
try this (worked for me with a gt48xlsi) sit on seat, push 123 (3 times), then push 1, then push 1 and 3 together and hold for approx. 3 seconds. this should turn the light blinking green and the switch is reset to factory settings. you should then be able to change the code as you wish doing the standard procedure.
The procedure that worked for me is this. sit on seat, push 123 (3 times) then push 1, then push 1 and 3 together and hold for approx. 3 seconds. this gets the light blinking green and evidently resets the switch to factory settings and you can then follow the standard procedure to change code. Evidently there is a brand new service bulletin on this that my dealer couldn't even look up. It is for 2015 model tractors. His factory rep had to tell him this procedure. good luck with this
Ted, I had same problem. I have a GTxlsi with a smart switch. Evedently there is a brand new service bulliten for the 2015 models. to fix this I did the following. sit on seat, push ssi button (the big one) then press 123 (3 times), then push 1, the push and hol the 1 and 3 together and hold for appox 3 seconds. it will then start blinking green. This evidently resets to factory settings and you can do the standard procedure tto change code from there. (woked for me). Good luck
