    Trying to change tpms threshold on a 18 Ram 2500 with a MS908S. All is up to date including the VCI. When I attempt to reconfigure the RF hub and enter the PIN the tool says it can't communicate with the RF hub. I can however see live data from the RF hub. Just this function doesn't seem to work. Is this a software issue? Has anyone had this issue and got a resolution?

    Sorry, you must be missing the security handshake, you need OEM tools like witech for
    chrysler to sync it to the bcm.
