ANSWER: On some newer Mack models the option to program the ESP control unit configuration is not available. If this is the case, you will need to “finish work”; remove this vehicle from the “recently selected” list; go to the top left of the screen and “work offline”. Now reconnect to the vehicle, but only in the offline mode. When asked for a model, select an older model like the CXU. You will need to connect to central systems after the operation has been selected.
