What is a Sunroof Control Module?
Electronically powered sunroofs use several sensors and a motor to control the operation of a sunroof. The sunroof control module will direct the motor based on the inputs from these sensors, thus preventing damage to the sunroof motor and regulator while allowing for increased and more sophisticated functionality.
How do Sunroof Control Modules work?
When the driver presses the switch to open the sunroof or the wireless control module communicates with the sunroof control module via the body control module, the sunroof control module with read the position of the sunroof and activate the sunroof motor until the sunroof position sensor requests that the sunroof motor stop. Also, when the sunroof is told to open, close or lift completely with a one touch function, the sunroof control module will keep the relay for the sunroof control module active until the sunroof position sensor detects the sunroof has completed movement through the entire range of travel.
What are the symptoms of a bad Sunroof Control Module?
Since the sunroof control module controls all aspects of sunroof operation, the sunroof control module can mimic any fault that can be caused by any part of the sunroof control system. This may be failing to open, close or lift, open, close or lift without request, or preventing closing due to a sensed obstruction that is not there.
Can I drive with a bad Sunroof Control Module?
If the sunroof is in the closed position and is not leaking water into the vehicle during inclement weather, the fuse for the sunroof can be removed to prevent complications from the sunroof control module failing to operate. Also, some vehicles have a manual handle to crank the sunroof open and closed, so this would also prevent complications. In all other circumstances, the sunroof control module should be diagnosed and repaired immediately to protect from theft and water damage.
