Active Grille Shutter

The grille shutter actuator positions the grille shutters based on commands from the PCM . The grille shutter moves 90 degrees from fully closed to fully open and, based on the position commanded by the PCM , is set in 1 of 16 positions (approximately 6 degrees between positions).

During normal operation, the grille shutter may be partially to fully open when the engine is off depending on the ambient temperature. After an engine starting event, a calibration of the grille shutter system occurs which typically takes 15-20 seconds. The grille shutter system performs the calibration sequence by detecting the end positions, open and closed. The calibration sequence can begin in either direction, open or closed, and continues until it is successful or a fault is sensed. A long pause may occur between the 2 portions (open/close) of the calibration sequence. If certain faults are present (shutter blocked or actuator error), a recalibration is initiated in an attempt to resolve the problem. If the problem is not resolved after a calibrated number of attempts (usually 3 or 4), a timer starts and sets a DTC when the timer reaches a predetermined limit.

The PCM communicates the desired position (open or closed) of the grille shutter based on various PCM inputs (vehicle speed, coolant temperature, ambient temperature, A/C system pressure, etc.). The PCM communicates to the grille shutter actuator via a LIN . The LIN supports bi-directional communication between the grille shutter actuator and PCM , allowing the grille shutter actuator to communicate position and fault information to the PCM .

The PCM sets grille shutter Diagnostic Trouble Codes (DTCs) when the fault information is communicated by the grille shutter actuator for a predetermined amount of time. Any failures of the LIN for over 10 seconds continuously results in the grille shutter actuator positioning the grille shutter fully open. There is no indication to the driver of the vehicle when a fault with the grille shutter system is present or a grille shutter DTC is set in the PCM .

Component Description

Grille Shutter Actuator

The grille shutter actuator is a smart motor which receives position requests from the PCM via the LIN . One of the grille shutter blinds connects to the grille shutter actuator using a retainer. The grille shutter actuator is serviced as an entire assembly, which includes the grille shutter, grille shutter actuator, retainer, housing and jumper harness.

Grille Shutter

The grille shutter is comprised of shutter blinds which are linked to each other. One of the individual shutter blinds is fixed to the grille shutter actuator. When the grille shutter actuator moves, it moves the attached shutter which causes the other linked shutters to move. The grille shutter is serviced as an entire assembly, which includes the grille shutter, grille shutter actuator, retainer, housing and jumper harness.
