    Hello, first time poster so forgive me if I'm in the wrong spot. I have a 2020 freightliner cascadia with the dd13 engine and a dt12 automatic transmission. We've installed a PTO on the transmission but can not get it to turn on via the in cab switch. This truck was equipped from the factory with the PTO prep kit. We have a computer from Diesel scanners and have played around with the programming, and pto does spin with enabling it from one of the computer settings, but not the switch. I guess the question is does anyone in this forum know how to enable the cab switch? Any help would be greatly appreciated, thank you!

    With DDL go into the PTO menu and enable the switch.

    I did do that , along with searching all the parameters, i believe they are all set to enable pto along with interlocks disabled. It will turn on with the laptop, but not the switch. The switch ramps up the rpm by 100 when turned on, but no indicator light, the light does come on when ignition is first turned on then goes out. The light will also turn on with the laptop so i feel its ok.

    Maybe try using DDL instead of some generic program.

    The motor should idle up when the switch is on. Maybe check those parameters.
