Ok to remove active shutters??

I thought people who removed these left the top and bottom one on so AGS would not set a CEL. After many readings, this is my belief. Thoughts? Thanks in advance.

If you want to totally remove them,hunt up Jason Dauria for one of his delete kits. You can find him on either Tuned Rams or High Performance Rams on facebook.that's who Corneilieous is referring to

Not true. AGS open when a temperature is reach and closes when the temperature is below a certain degree.
AGS do not remain open.
Mine opens at 220 and closes soon after. The temperature drops to 190 or so only because the the cooler radiator water enters the block and it’s takes a very short time for the thermostat to close.

Found the following under the U11E9 DTC:

Theory of Operation

The Active Grill Shutter (AGS) system is controlled by the Powertrain Control Module (PCM) over a dedicated network Local Interconnect Network (LIN) bus. The Active Grill Shutters perform an initialization each time the vehicle is started. The initialization can be used as a quick way to validate the operation of the AGS. An AGS validation can be performed by starting the engine and observing the grill shutters. The shutters will cycle to the fully open position and then to the fully closed positions to initialize and learn the hard stops on the grill shutter frame for each key cycle. The grill shutter vanes can be commanded to the open or closed positions using the system test found under PCM in the scan tool.

If the AGS smart module detects the grill shutters are jammed, it will attempt to free them by cycling the shutters from the open to close positions 3 times. If this condition is detected when the ambient air temperature is greater than 40°F, the MIL will illuminate and a Diagnostic Trouble Code (DTC) will set. If the ambient air temperature is below 40°F, and a jammed condition is detected, the smart module will assume the shutters are frozen and will not illuminate the MIL or set a DTC.

Monitored and Set Conditions

When Monitored: This diagnostic routine runs continuously when the following conditions are met:

With the engine running and battery voltage between 11.0 and 16.0 volts.

Ambient Air Temperature or Engine Coolant Temperature above 19.4°F.

DTC Set Conditions:

The PCM does not receive a valid LIN BUS message from the Active Grill Shutter Assembly for 2.6 seconds.

Default Actions:

MIL is illuminated on the second consecutive trip that the diagnostic fails.

If the AGS detects a LIN bus error it will default to open position.

NOTE: The Active Air Dam uses the same LIN circuit for fault detection.
