I have looked every where for help with trying to activate the SST on my 2017 F150 and I keep ending up here. I changed my ride from a column shift to a floor shift with the H/S switch and the +- switch. I changed the 4’’ speedometer that has PRND321 to a 8’’ with PRNDM21. I wired everything up. The H/S works and the gear select works. The power for the SST is live. I have used FORScan and followed Haulinbass02 steps on how to do this as he did it with his 2013. I used the news version and I also tried the same version he used but only 2 things come up for me and one of them is not the SST like it did for him. Now his is a 12th gen truck and mine is a 13th gen and I’m thinking that may be my problem. it could be the elm327 with toggle switch that my be the problem but not sure about it. Will be very grateful for any help with this and thank you in advance.

 

Welcome..

I would say that it is almost certainly a programming mistake because those are not at all the same trucks.

have you checked or asked in the FORSCAN thread?

 

No not yet. I’ll try that next. Thank you
