Hello ,my name is Joe

The preferred method of deactivating the ICON ™ system is to turn off the cruise control switch. To restart the engine, after deactivating the ICON ™ system, cycle the keyswitch from ON to OFF, then manually restart the engine.

After the ICON ™ system has been activated in either engine mode (including keyless engine mode) or cab comfort mode, the ICON ™ system will be deactivated if any of the following occurs:

Interlock switch open (neutral, parking, hood)
Vehicle speed greater than 0 mph
A Fault becomes active in the ICON ™ system
(Aftermarket systems only) accelerator is depressed with keyswitch on or off (keyless engine mode) before first shutdown
Cruise control switch turned off

Ok ,

A permanent disable will require removal of the Icon wire harness - depending on the application and the version of the system.

The following parameters must also be manually reprogrammed in the ECM using the Cummins Insite software:
  1. Idle shutdown
  2. Idle shutdown override enable
  3. Idle shutdown in PTO enable
  4. Ambient air temperature idle shutdown override
  5. Automatic mode antitheft devices
