The function diagram for the RSE includes the following:
• Electronic Control Module (ECM)
• Intake Air Temperature (IAT) sensor
• Engine Coolant Temperature (ECT) sensor
• Manifold Air Temperature (MAT) sensor
• Shutter solenoid
• Electronic System Controller (ESC)
• Drivetrain Datalink (CAN 1)
Function
The Radiator Shutter Enable (RSE) feature provides the correct logic to open or close the radiator shutters
(energize or de-energize a solenoid). Closing the shutters will keep the engine warm during cold weather operation. This provides faster warm up of the passenger cab and enables faster windshield defrosting.
