\This bulletin applies to 2013-2015 RAM 1500 trucks equipped with Active Grille Shutters (AGS). 

If the fascia is removed for any reason during service, the MIL may illuminate and DTC U11E9 may be stored or active (lost communication with AGS is set if the vehicle is started while the AGS electrical harness connector is disconnected). 

Confirm that the AGS electrical harness connector is properly connected, and clear any DTCs that may have been set. Perform a test drive and then use a scan tool to check for any set or pending DTCs.
